IMGUI_APIvoidEndFrame();// ends the Dear ImGui frame. automatically called by Render(). If you don't need to render data (skipping rendering) you may call EndFrame() without Render()... but you'll have wasted CPU already! If you don't need to render, better to not create any windows and not call NewFrame() at all!
IMGUI_APIvoidShowDemoWindow(bool*p_open=NULL);// create Demo window. demonstrate most ImGui features. call this to learn about the library! try to make it always available in your application!
IMGUI_APIvoidShowIDStackToolWindow(bool*p_open=NULL);// create Stack Tool window. hover items with mouse to query information about the source of their unique ID.

IMPORTANT: If you are trying to check whether your mouse should be dispatched to Dear ImGui or to your underlying app, you should not use this function! Use the 'io.WantCaptureMouse' boolean for that! Refer to FAQ entry "How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?" for details.

Use -1 for both min and max of same axis to preserve current size (which itself is a constraint). Use callback to apply non-trivial programmatic constraints.
IMGUI_APIvoidSetNextWindowContentSize(constImVec2&size);// set next window content size (~ scrollable client area, which enforce the range of scrollbars). Not including window decorations (title bar, menu bar, etc.) nor WindowPadding. set an axis to 0.0f to leave it automatic. call before Begin()
IMGUI_APIvoidSetNextWindowBgAlpha(floatalpha);// set next window background color alpha. helper to easily override the Alpha component of ImGuiCol_WindowBg/ChildBg/PopupBg. you may also use ImGuiWindowFlags_NoBackground.
IMGUI_APIvoidSetWindowPos(constImVec2&pos,ImGuiCondcond=0);// (not recommended) set current window position - call within Begin()/End(). prefer using SetNextWindowPos(), as this may incur tearing and side-effects.
IMGUI_APIvoidSetWindowSize(constImVec2&size,ImGuiCondcond=0);// (not recommended) set current window size - call within Begin()/End(). set to ImVec2(0, 0) to force an auto-fit. prefer using SetNextWindowSize(), as this may incur tearing and minor side-effects.

// - Retrieve available space from a given point. GetContentRegionAvail() is frequently useful.
// - Those functions are bound to be redesigned (they are confusing, incomplete and the Min/Max return values are in local window coordinates which increases confusion)
IMGUI_APIImVec2GetContentRegionMax();// current content boundaries (typically window boundaries including scrolling, or current column boundaries), in windows coordinates
IMGUI_APIImVec2GetWindowContentRegionMax();// content boundaries max for the full window (roughly (0,0)+Size-Scroll) where Size can be overridden with SetNextWindowContentSize(), in window coordinates
IMGUI_APIvoidSetScrollHereX(floatcenter_x_ratio=0.5f);// adjust scrolling amount to make current cursor position visible. center_x_ratio=0.0: left, 0.5: center, 1.0: right. When using to make a "default/current item" visible, consider using SetItemDefaultFocus() instead.
IMGUI_APIvoidSetScrollHereY(floatcenter_y_ratio=0.5f);// adjust scrolling amount to make current cursor position visible. center_y_ratio=0.0: top, 0.5: center, 1.0: bottom. When using to make a "default/current item" visible, consider using SetItemDefaultFocus() instead.
IMGUI_APIvoidSetScrollFromPosX(floatlocal_x,floatcenter_x_ratio=0.5f);// adjust scrolling amount to make given position visible. Generally GetCursorStartPos() + offset to compute a valid position.

IMGUI_APIvoidPushTabStop(booltab_stop);// == tab stop enable. Allow focusing using TAB/Shift-TAB, enabled by default but you can disable it for certain widgets
IMGUI_APIvoidPushButtonRepeat(boolrepeat);// in 'repeat' mode, Button*() functions return repeated true in a typematic manner (using io.KeyRepeatDelay/io.KeyRepeatRate setting). Note that you can call IsItemActive() after any Button() to tell if the button is held in the current frame.
IMGUI_APIvoidPushItemWidth(floatitem_width);// push width of items for common large "item+label" widgets. >0.0f: width in pixels, <0.0f align xx pixels to the right of window (so -FLT_MIN always align width to the right side).
IMGUI_APIvoidSetNextItemWidth(floatitem_width);// set width of the _next_ common large "item+label" widget. >0.0f: width in pixels, <0.0f align xx pixels to the right of window (so -FLT_MIN always align width to the right side)
IMGUI_APIfloatCalcItemWidth();// width of item given pushed settings and current cursor position. NOT necessarily the width of last item unlike most 'Item' functions.
IMGUI_APIvoidPushTextWrapPos(floatwrap_local_pos_x=0.0f);// push word-wrapping position for Text*() commands. < 0.0f: no wrapping; 0.0f: wrap to end of window (or column); > 0.0f: wrap at 'wrap_pos_x' position in window local space
IMGUI_APIfloatGetFontSize();// get current font size (= height in pixels) of current font with current scale applied
IMGUI_APIImVec2GetFontTexUvWhitePixel();// get UV coordinate for a while pixel, useful to draw custom shapes via the ImDrawList API
IMGUI_APIImU32GetColorU32(ImGuiColidx,floatalpha_mul=1.0f);// retrieve given style color with style alpha applied and optional extra alpha multiplier, packed as a 32-bit value suitable for ImDrawList

IMGUI_APIconstImVec4&GetStyleColorVec4(ImGuiColidx);// retrieve style color as stored in ImGuiStyle structure. use to feed back into PushStyleColor(), otherwise use GetColorU32() to get style color with style alpha baked in.
// - GetCursorScreenPos() = GetCursorPos() + GetWindowPos(). GetWindowPos() is almost only ever useful to convert from window-local to absolute coordinates.
IMGUI_APIImVec2GetCursorScreenPos();// cursor position in absolute coordinates (prefer using this, also more useful to work with ImDrawList API).
IMGUI_APIvoidSetCursorScreenPos(constImVec2&pos);// cursor position in absolute coordinates
IMGUI_APIImVec2GetCursorPos();// [window-local] cursor position in window coordinates (relative to window position)
IMGUI_APIvoidSameLine(floatoffset_from_start_x=0.0f,floatspacing=-1.0f);// call between widgets or groups to layout them horizontally. X position given in window coordinates.
IMGUI_APIvoidDummy(constImVec2&size);// add a dummy item of given size. unlike InvisibleButton(), Dummy() won't take the mouse click or be navigable into.
IMGUI_APIvoidBeginGroup();// lock horizontal starting position
IMGUI_APIvoidEndGroup();// unlock horizontal starting position + capture the whole group bounding box into one "item" (so you can use IsItemHovered() or layout primitives such as SameLine() on whole group, etc.)
IMGUI_APIvoidAlignTextToFramePadding();// vertically align upcoming text baseline to FramePadding.y so that it will align properly to regularly framed items (call if you have text on a line before a framed item)
IMGUI_APIfloatGetTextLineHeight();// ~ FontSize
IMGUI_APIfloatGetTextLineHeightWithSpacing();// ~ FontSize + style.ItemSpacing.y (distance in pixels between 2 consecutive lines of text)
IMGUI_APIImGuiIDGetID(constchar*str_id);// calculate unique ID (hash of whole ID stack + given parameter). e.g. if you want to query into ImGuiStorage yourself
IMGUI_APIvoidTextUnformatted(constchar*text,constchar*text_end=NULL);// raw text without formatting. Roughly equivalent to Text("%s", text) but: A) doesn't require null terminated string if 'text_end' is specified, B) it's faster, no memory copy is done, no buffer size limits, recommended for long chunks of text.
IMGUI_APIvoidText(constchar*fmt,...)IM_FMTARGS(1);// formatted text
IMGUI_APIvoidTextWrapped(constchar*fmt,...)IM_FMTARGS(1);// shortcut for PushTextWrapPos(0.0f); Text(fmt, ...); PopTextWrapPos();. Note that this won't work on an auto-resizing window if there's no other widgets to extend the window width, yoy may need to set a size using SetNextWindowSize().
IMGUI_APIboolInvisibleButton(constchar*str_id,constImVec2&size,ImGuiButtonFlagsflags=0);// flexible button behavior without the visuals, frequently useful to build custom behaviors using the public api (along with IsItemActive, IsItemHovered, etc.)
IMGUI_APIvoidBullet();// draw a small circle + keep the cursor on the same line. advance cursor x position by GetTreeNodeToLabelSpacing(), same distance that TreeNode() uses
// - The old Combo() api are helpers over BeginCombo()/EndCombo() which are kept available for convenience purpose. This is analogous to how ListBox are created.
IMGUI_APIboolCombo(constchar*label,int*current_item,constchar*items_separated_by_zeros,intpopup_max_height_in_items=-1);// Separate items with \0 within a string, end item-list with \0\0. e.g. "One\0Two\0Three\0"
// - CTRL+Click on any drag box to turn them into an input box. Manually input values aren't clamped by default and can go off-bounds. Use ImGuiSliderFlags_AlwaysClamp to always clamp.
// the array syntax is just a way to document the number of elements that are expected to be accessible. You can pass address of your first element out of a contiguous set, e.g. &myvector.x
// - Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.
// - Speed are per-pixel of mouse movement (v_speed=0.2f: mouse needs to move by 5 pixels to increase value by 1). For gamepad/keyboard navigation, minimum speed is Max(v_speed, minimum_step_at_given_precision).
// - Use v_min < v_max to clamp edits to given limits. Note that CTRL+Click manual input can override those limits if ImGuiSliderFlags_AlwaysClamp is not used.
// - Legacy: Pre-1.78 there are DragXXX() function signatures that take a final `float power=1.0f' argument instead of the `ImGuiSliderFlags flags=0' argument.
// If you get a warning converting a float to ImGuiSliderFlags, read https://github.com/ocornut/imgui/issues/3361
IMGUI_APIboolDragFloat(constchar*label,float*v,floatv_speed=1.0f,floatv_min=0.0f,floatv_max=0.0f,constchar*format="%.3f",ImGuiSliderFlagsflags=0);// If v_min >= v_max we have no bound

// - CTRL+Click on any slider to turn them into an input box. Manually input values aren't clamped by default and can go off-bounds. Use ImGuiSliderFlags_AlwaysClamp to always clamp.
// - Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.
// - Legacy: Pre-1.78 there are SliderXXX() function signatures that take a final `float power=1.0f' argument instead of the `ImGuiSliderFlags flags=0' argument.
IMGUI_APIboolSliderFloat(constchar*label,float*v,floatv_min,floatv_max,constchar*format="%.3f",ImGuiSliderFlagsflags=0);// adjust format to decorate the value with a prefix or a suffix for in-slider labels or unit display.
// Widgets: Color Editor/Picker (tip: the ColorEdit* functions have a little color square that can be left-clicked to open a picker, and right-clicked to open an option menu.)
// - Note that in C++ a 'float v[X]' function argument is the _same_ as 'float* v', the array syntax is just a way to document the number of elements that are expected to be accessible.
IMGUI_APIboolColorButton(constchar*desc_id,constImVec4&col,ImGuiColorEditFlagsflags=0,constImVec2&size=ImVec2(0,0));// display a color square/button, hover for details, return true when pressed.
IMGUI_APIvoidSetColorEditOptions(ImGuiColorEditFlagsflags);// initialize current options (generally on application startup) if you want to select a default format, picker type, etc. User will be able to change many settings, unless you pass the _NoOptions flag to your calls.
// - TreeNode functions return true when the node is open, in which case you need to also call TreePop() when you are finished displaying the tree node contents.
IMGUI_APIboolTreeNode(constchar*str_id,constchar*fmt,...)IM_FMTARGS(2);// helper variation to easily decorelate the id from the displayed string. Read the FAQ about why and how to use ID. to align arbitrary text at the same level as a TreeNode() you can use Bullet().
IMGUI_APIvoidTreePush(constchar*str_id);// ~ Indent()+PushID(). Already called by TreeNode() when returning true, but you can call TreePush/TreePop yourself if desired.
IMGUI_APIfloatGetTreeNodeToLabelSpacing();// horizontal distance preceding label when using TreeNode*() or Bullet() == (g.FontSize + style.FramePadding.x*2) for a regular unframed TreeNode
IMGUI_APIboolCollapsingHeader(constchar*label,ImGuiTreeNodeFlagsflags=0);// if returning 'true' the header is open. doesn't indent nor push on ID stack. user doesn't have to call TreePop().
IMGUI_APIboolCollapsingHeader(constchar*label,bool*p_visible,ImGuiTreeNodeFlagsflags=0);// when 'p_visible != NULL': if '*p_visible==true' display an additional small close button on upper right of the header which will set the bool to false when clicked, if '*p_visible==false' don't display the header.
// - Neighbors selectable extend their highlight bounds in order to leave no gap between them. This is so a series of selected Selectable appear contiguous.
IMGUI_APIboolSelectable(constchar*label,boolselected=false,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool selected" carry the selection state (read-only). Selectable() is clicked is returns true so you can modify your selection state. size.x==0.0: use remaining width, size.x>0.0: specify width. size.y==0.0: use label height, size.y>0.0: specify height
IMGUI_APIboolSelectable(constchar*label,bool*p_selected,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool* p_selected" point to the selection state (read-write), as a convenient helper.
// - This is essentially a thin wrapper to using BeginChild/EndChild with the ImGuiChildFlags_FrameStyle flag for stylistic changes + displaying a label.
// - You can submit contents and manage your selection state however you want it, by creating e.g. Selectable() or any other items.
// - The simplified/old ListBox() api are helpers over BeginListBox()/EndListBox() which are kept available for convenience purpose. This is analoguous to how Combos are created.
// - Choose frame width: size.x > 0.0f: custom / size.x < 0.0f or -FLT_MIN: right-align / size.x = 0.0f (default): use current ItemWidth
// - Choose frame height: size.y > 0.0f: custom / size.y < 0.0f or -FLT_MIN: bottom-align / size.y = 0.0f (default): arbitrary default height which can fit ~7 items
IMGUI_APIboolBeginListBox(constchar*label,constImVec2&size=ImVec2(0,0));// open a framed scrolling region
IMGUI_APIvoidEndListBox();// only call EndListBox() if BeginListBox() returned true!
// - Those are merely shortcut to calling Text() with a format string. Output single value in "name: value" format (tip: freely declare more in your code to handle your types. you can add functions to the ImGui namespace)
// - A tooltip window can contain items of any types.
// - SetTooltip() is more or less a shortcut for the 'if (BeginTooltip()) { Text(...); EndTooltip(); }' idiom (with a subtlety that it discard any previously submitted tooltip)
IMGUI_APIvoidSetTooltip(constchar*fmt,...)IM_FMTARGS(1);// set a text-only tooltip. Often used after a ImGui::IsItemHovered() check. Override any previous call to SetTooltip().
// - BeginItemTooltip() is a shortcut for the 'if (IsItemHovered(ImGuiHoveredFlags_ForTooltip) && BeginTooltip())' idiom.
// - SetItemTooltip() is a shortcut for the 'if (IsItemHovered(ImGuiHoveredFlags_ForTooltip)) { SetTooltip(...); }' idiom.
// - Where 'ImGuiHoveredFlags_ForTooltip' itself is a shortcut to use 'style.HoverFlagsForTooltipMouse' or 'style.HoverFlagsForTooltipNav' depending on active input type. For mouse it defaults to 'ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort'.
IMGUI_APIvoidSetItemTooltip(constchar*fmt,...)IM_FMTARGS(1);// set a text-only tooltip if preceding item was hovered. override any previous call to SetTooltip().
// - They block normal mouse hovering detection (and therefore most mouse interactions) behind them.
// - If not modal: they can be closed by clicking anywhere outside them, or by pressing ESCAPE.
// - Their visibility state (~bool) is held internally instead of being held by the programmer as we are used to with regular Begin*() calls.
// - The 3 properties above are related: we need to retain popup visibility state in the library because popups may be closed as any time.
// - You can bypass the hovering restriction by using ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered().
// - IMPORTANT: Popup identifiers are relative to the current ID stack, so OpenPopup and BeginPopup generally needs to be at the same level of the stack.
// This is sometimes leading to confusing mistakes. May rework this in the future.
// - BeginPopup(): query popup state, if open start appending into the window. Call EndPopup() afterwards if returned true. ImGuiWindowFlags are forwarded to the window.
IMGUI_APIboolBeginPopup(constchar*str_id,ImGuiWindowFlagsflags=0);// return true if the popup is open, and you can start outputting to it.
IMGUI_APIboolBeginPopupModal(constchar*name,bool*p_open=NULL,ImGuiWindowFlagsflags=0);// return true if the modal is open, and you can start outputting to it.
IMGUI_APIvoidEndPopup();// only call EndPopup() if BeginPopupXXX() returns true!
// - Use ImGuiPopupFlags_NoOpenOverExistingPopup to avoid opening a popup if there's already one at the same level. This is equivalent to e.g. testing for !IsAnyPopupOpen() prior to OpenPopup().
// - IMPORTANT: Notice that for OpenPopupOnItemClick() we exceptionally default flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter
IMGUI_APIvoidOpenPopupOnItemClick(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// helper to open popup when clicked on last item. Default to ImGuiPopupFlags_MouseButtonRight == 1. (note: actually triggers on the mouse _released_ event to be consistent with popup behaviors)
// - IMPORTANT: Notice that BeginPopupContextXXX takes ImGuiPopupFlags just like OpenPopup() and unlike BeginPopup(). For full consistency, we may add ImGuiWindowFlags to the BeginPopupContextXXX functions in the future.
// - IMPORTANT: Notice that we exceptionally default their flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter, so if you add other flags remember to re-add the ImGuiPopupFlags_MouseButtonRight.
IMGUI_APIboolBeginPopupContextItem(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked on last item. Use str_id==NULL to associate the popup to previous item. If you want to use that on a non-interactive item such as Text() you need to pass in an explicit ID here. read comments in .cpp!
IMGUI_APIboolBeginPopupContextWindow(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked on current window.
IMGUI_APIboolBeginPopupContextVoid(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked in void (where there are no windows).
IMGUI_APIboolTableNextColumn();// append into the next column (or first column of next row if currently in last column). Return true when column is visible.
IMGUI_APIboolTableSetColumnIndex(intcolumn_n);// append into the specified column. Return true when column is visible.
IMGUI_APIvoidTableHeadersRow();// submit a row with headers cells based on data provided to TableSetupColumn() + submit context menu
IMGUI_APIvoidTableAngledHeadersRow();// submit a row with angled headers for every column with the ImGuiTableColumnFlags_AngledHeader flag. MUST BE FIRST ROW.
IMGUI_APIImGuiTableSortSpecs*TableGetSortSpecs();// get latest sort specs for the table (NULL if not sorting). Lifetime: don't hold on this pointer over multiple frames or past any subsequent call to BeginTable().
IMGUI_APIconstchar*TableGetColumnName(intcolumn_n=-1);// return "" if column didn't have a name declared by TableSetupColumn(). Pass -1 to use current column.
IMGUI_APIImGuiTableColumnFlagsTableGetColumnFlags(intcolumn_n=-1);// return column flags so you can query their Enabled/Visible/Sorted/Hovered status flags. Pass -1 to use current column.
IMGUI_APIvoidTableSetColumnEnabled(intcolumn_n,boolv);// change user accessible enabled/disabled state of a column. Set to false to hide the column. User can use the context menu to change this themselves (right-click in headers, or right-click in columns body with ImGuiTableFlags_ContextMenuInBody)
IMGUI_APIvoidTableSetBgColor(ImGuiTableBgTargettarget,ImU32color,intcolumn_n=-1);// change the color of a cell, row, or column. See ImGuiTableBgTarget_ flags for details.
IMGUI_APIvoidNextColumn();// next column, defaults to current row or next row if the current row is finished
IMGUI_APIintGetColumnIndex();// get current column index
IMGUI_APIfloatGetColumnWidth(intcolumn_index=-1);// get column width (in pixels). pass -1 to use current column
IMGUI_APIvoidSetColumnWidth(intcolumn_index,floatwidth);// set column width (in pixels). pass -1 to use current column
IMGUI_APIfloatGetColumnOffset(intcolumn_index=-1);// get position of column line (in pixels, from the left side of the contents region). pass -1 to use current column, otherwise 0..GetColumnsCount() inclusive. column 0 is typically 0.0f
IMGUI_APIvoidSetColumnOffset(intcolumn_index,floatoffset_x);// set position of column line (in pixels, from the left side of the contents region). pass -1 to use current column
IMGUI_APIboolTabItemButton(constchar*label,ImGuiTabItemFlagsflags=0);// create a Tab behaving like a button. return true when clicked. cannot be selected in the tab bar.
IMGUI_APIvoidSetTabItemClosed(constchar*tab_or_docked_window_label);// notify TabBar or Docking system of a closed tab/window ahead (useful to reduce visual flicker on reorderable tab bars). For tab-bar: call after BeginTabBar() and before Tab submissions. Otherwise call with a window name.
// - On source items, call BeginDragDropSource(), if it returns true also call SetDragDropPayload() + EndDragDropSource().
// - On target candidates, call BeginDragDropTarget(), if it returns true also call AcceptDragDropPayload() + EndDragDropTarget().
// - If you stop calling BeginDragDropSource() the payload is preserved however it won't have a preview tooltip (we currently display a fallback "..." tooltip, see #1725)
// - An item can be both drag source and drop target.
IMGUI_APIboolBeginDragDropSource(ImGuiDragDropFlagsflags=0);// call after submitting an item which may be dragged. when this return true, you can call SetDragDropPayload() + EndDragDropSource()
IMGUI_APIboolSetDragDropPayload(constchar*type,constvoid*data,size_tsz,ImGuiCondcond=0);// type is a user defined string of maximum 32 characters. Strings starting with '_' are reserved for dear imgui internal types. Data is copied and held by imgui. Return true when payload has been accepted.
IMGUI_APIboolBeginDragDropTarget();// call after submitting an item that may receive a payload. If this returns true, you can call AcceptDragDropPayload() + EndDragDropTarget()
IMGUI_APIconstImGuiPayload*AcceptDragDropPayload(constchar*type,ImGuiDragDropFlagsflags=0);// accept contents of a given type. If ImGuiDragDropFlags_AcceptBeforeDelivery is set you can peek into the payload before the mouse button is released.
IMGUI_APIvoidEndDragDropTarget();// only call EndDragDropTarget() if BeginDragDropTarget() returns true!
IMGUI_APIconstImGuiPayload*GetDragDropPayload();// peek directly into the current payload from anywhere. returns NULL when drag and drop is finished or inactive. use ImGuiPayload::IsDataType() to test for the payload type.
// - Those can be nested but it cannot be used to enable an already disabled section (a single BeginDisabled(true) in the stack is enough to keep everything disabled)
// - BeginDisabled(false) essentially does nothing useful but is provided to facilitate use of boolean expressions. If you can avoid calling BeginDisabled(False)/EndDisabled() best to avoid it.
IMGUI_APIvoidSetKeyboardFocusHere(intoffset=0);// focus keyboard on the next widget. Use positive 'offset' to access sub components of a multiple component widget. Use -1 to access previous widget.
IMGUI_APIvoidSetNextItemAllowOverlap();// allow next item to be overlapped by a subsequent item. Useful with invisible buttons, selectable, treenode covering an area where subsequent items may need to be added. Note that both Selectable() and TreeNode() have dedicated flags doing this.
IMGUI_APIboolIsItemHovered(ImGuiHoveredFlagsflags=0);// is the last item hovered? (and usable, aka not blocked by a popup, etc.). See ImGuiHoveredFlags for more options.
IMGUI_APIboolIsItemActive();// is the last item active? (e.g. button being held, text field being edited. This will continuously return true while holding mouse button on an item. Items that don't interact will always return false)
IMGUI_APIboolIsItemClicked(ImGuiMouseButtonmouse_button=0);// is the last item hovered and mouse clicked on? (**) == IsMouseClicked(mouse_button) && IsItemHovered()Important. (**) this is NOT equivalent to the behavior of e.g. Button(). Read comments in function definition.
IMGUI_APIboolIsItemEdited();// did the last item modify its underlying value this frame? or was pressed? This is generally the same as the "bool" return value of many widgets.
IMGUI_APIboolIsItemDeactivated();// was the last item just made inactive (item was previously active). Useful for Undo/Redo patterns with widgets that require continuous editing.
IMGUI_APIboolIsItemDeactivatedAfterEdit();// was the last item just made inactive and made a value change when it was active? (e.g. Slider/Drag moved). Useful for Undo/Redo patterns with widgets that require continuous editing. Note that you may get false positives (some widgets such as Combo()/ListBox()/Selectable() will return true even when clicking an already selected item).
IMGUI_APIImDrawList*GetBackgroundDrawList();// this draw list will be the first rendered one. Useful to quickly draw shapes/text behind dear imgui contents.
IMGUI_APIImDrawList*GetForegroundDrawList();// this draw list will be the last rendered one. Useful to quickly draw shapes/text over dear imgui contents.
IMGUI_APIboolIsRectVisible(constImVec2&size);// test if rectangle (of given size, starting from cursor position) is visible / not clipped.
IMGUI_APIboolIsRectVisible(constImVec2&rect_min,constImVec2&rect_max);// test if rectangle (in screen space) is visible / not clipped. to perform coarse clipping on user's side.
IMGUI_APIvoidSetStateStorage(ImGuiStorage*storage);// replace current window storage with our own (if you want to manipulate it yourself, typically clear subsection of it)
// - the ImGuiKey enum contains all possible keyboard, mouse and gamepad inputs (e.g. ImGuiKey_A, ImGuiKey_MouseLeft, ImGuiKey_GamepadDpadUp...).
// - before v1.87, we used ImGuiKey to carry native/user indices as defined by each backends. About use of those legacy ImGuiKey values:
// - without IMGUI_DISABLE_OBSOLETE_KEYIO (legacy support): you can still use your legacy native/user indices (< 512) according to how your backend/engine stored them in io.KeysDown[], but need to cast them to ImGuiKey.
// - with IMGUI_DISABLE_OBSOLETE_KEYIO (this is the way forward): any use of ImGuiKey will assert with key < 512. GetKeyIndex() is pass-through and therefore deprecated (gone if IMGUI_DISABLE_OBSOLETE_KEYIO is defined).
IMGUI_APIboolIsKeyPressed(ImGuiKeykey,boolrepeat=true);// was key pressed (went from !Down to Down)? if repeat=true, uses io.KeyRepeatDelay / KeyRepeatRate
IMGUI_APIboolIsKeyReleased(ImGuiKeykey);// was key released (went from Down to !Down)?
IMGUI_APIboolIsKeyChordPressed(ImGuiKeyChordkey_chord);// was key chord (mods + key) pressed, e.g. you can pass 'ImGuiMod_Ctrl | ImGuiKey_S' as a key-chord. This doesn't do any routing or focus check, please consider using Shortcut() function instead.
IMGUI_APIintGetKeyPressedAmount(ImGuiKeykey,floatrepeat_delay,floatrate);// uses provided repeat rate/delay. return a count, most often 0 or 1 but might be >1 if RepeatRate is small enough that DeltaTime > RepeatRate
IMGUI_APIconstchar*GetKeyName(ImGuiKeykey);// [DEBUG] returns English name of the key. Those names a provided for debugging purpose and are not meant to be saved persistently not compared.
IMGUI_APIvoidSetNextFrameWantCaptureKeyboard(boolwant_capture_keyboard);// Override io.WantCaptureKeyboard flag next frame (said flag is left for your application to handle, typically when true it instructs your app to ignore inputs). e.g. force capture keyboard when your widget is being hovered. This is equivalent to setting "io.WantCaptureKeyboard = want_capture_keyboard"; after the next NewFrame() call.
// only ImGuiMod_XXX values are legal to combine with an ImGuiKey. You CANNOT combine two ImGuiKey values.
// - The general idea is that several callers may register interest in a shortcut, and only one owner gets it.
// Parent -> call Shortcut(Ctrl+S) // When Parent is focused, Parent gets the shortcut.
// Child1 -> call Shortcut(Ctrl+S) // When Child1 is focused, Child1 gets the shortcut (Child1 overrides Parent shortcuts)
// Child2 -> no call // When Child2 is focused, Parent gets the shortcut.
// The whole system is order independent, so if Child1 makes its calls before Parent, results will be identical.
// This is an important property as it facilitate working with foreign code or larger codebase.
// - To understand the difference:
// - IsKeyChordPressed() compares mods and call IsKeyPressed() -> function has no side-effect.
// - Shortcut() submits a route, routes are resolved, if it currently can be routed it calls IsKeyChordPressed() -> function has (desirable) side-effects as it can prevents another call from getting the route.
// - Visualize registered routes in 'Metrics/Debugger->Inputs'.
// - To refer to a mouse button, you may use named enums in your code e.g. ImGuiMouseButton_Left, ImGuiMouseButton_Right.
// - You can also use regular integer: it is forever guaranteed that 0=Left, 1=Right, 2=Middle.
// - Dragging operations are only reported after mouse has moved a certain distance away from the initial clicking position (see 'lock_threshold' and 'io.MouseDraggingThreshold')
IMGUI_APIboolIsMouseDown(ImGuiMouseButtonbutton);// is mouse button held?
IMGUI_APIboolIsMouseClicked(ImGuiMouseButtonbutton,boolrepeat=false);// did mouse button clicked? (went from !Down to Down). Same as GetMouseClickedCount() == 1.
IMGUI_APIboolIsMouseDoubleClicked(ImGuiMouseButtonbutton);// did mouse button double-clicked? Same as GetMouseClickedCount() == 2. (note that a double-click will also report IsMouseClicked() == true)
IMGUI_APIintGetMouseClickedCount(ImGuiMouseButtonbutton);// return the number of successive mouse-clicks at the time where a click happen (otherwise 0).
IMGUI_APIboolIsMouseHoveringRect(constImVec2&r_min,constImVec2&r_max,boolclip=true);// is mouse hovering given bounding rect (in screen space). clipped by current clipping settings, but disregarding of other consideration of focus/window ordering/popup-block.
IMGUI_APIboolIsAnyMouseDown();// [WILL OBSOLETE] is any mouse button held? This was designed for backends, but prefer having backend maintain a mask of held mouse buttons, because upcoming input queue system will make this invalid.
IMGUI_APIImVec2GetMousePosOnOpeningCurrentPopup();// retrieve mouse position at the time of opening popup we have BeginPopup() into (helper to avoid user backing that value themselves)
IMGUI_APIboolIsMouseDragging(ImGuiMouseButtonbutton,floatlock_threshold=-1.0f);// is mouse dragging? (uses io.MouseDraggingThreshold if lock_threshold < 0.0f)
IMGUI_APIImVec2GetMouseDragDelta(ImGuiMouseButtonbutton=0,floatlock_threshold=-1.0f);// return the delta from the initial clicking position while the mouse button is pressed or was just released. This is locked and return 0.0f until the mouse moves past a distance threshold at least once (uses io.MouseDraggingThreshold if lock_threshold < 0.0f)
IMGUI_APIImGuiMouseCursorGetMouseCursor();// get desired mouse cursor shape. Important: reset in ImGui::NewFrame(), this is updated during the frame. valid before Render(). If you use software rendering by setting io.MouseDrawCursor ImGui will render those for you
IMGUI_APIvoidSetMouseCursor(ImGuiMouseCursorcursor_type);// set desired mouse cursor shape
IMGUI_APIvoidSetNextFrameWantCaptureMouse(boolwant_capture_mouse);// Override io.WantCaptureMouse flag next frame (said flag is left for your application to handle, typical when true it instucts your app to ignore inputs). This is equivalent to setting "io.WantCaptureMouse = want_capture_mouse;" after the next NewFrame() call.
// - Important: default value "imgui.ini" is relative to current working dir! Most apps will want to lock this to an absolute path (e.g. same path as executables).
IMGUI_APIvoidLoadIniSettingsFromDisk(constchar*ini_filename);// call after CreateContext() and before the first call to NewFrame(). NewFrame() automatically calls LoadIniSettingsFromDisk(io.IniFilename).
IMGUI_APIvoidLoadIniSettingsFromMemory(constchar*ini_data,size_tini_size=0);// call after CreateContext() and before the first call to NewFrame() to provide .ini data from your own data source.
IMGUI_APIvoidSaveIniSettingsToDisk(constchar*ini_filename);// this is automatically called (if io.IniFilename is not empty) a few seconds after any modification that should be reflected in the .ini file (and also by DestroyContext).
IMGUI_APIconstchar*SaveIniSettingsToMemory(size_t*out_ini_size=NULL);// return a zero-terminated string with the .ini data which you can save by your own mean. call when io.WantSaveIniSettings is set, then save data by your own mean and clear io.WantSaveIniSettings.
IMGUI_APIboolDebugCheckVersionAndDataLayout(constchar*version_str,size_tsz_io,size_tsz_style,size_tsz_vec2,size_tsz_vec4,size_tsz_drawvert,size_tsz_drawidx);// This is called by IMGUI_CHECKVERSION() macro.
ImGuiWindowFlags_NoScrollWithMouse=1<<4,// Disable user vertically scrolling with mouse wheel. On child window, mouse wheel will be forwarded to the parent unless NoScrollbar is also set.
ImGuiWindowFlags_NoCollapse=1<<5,// Disable user collapsing window by double-clicking on it. Also referred to as Window Menu Button (e.g. within a docking node).
ImGuiWindowFlags_NoBackground=1<<7,// Disable drawing background color (WindowBg, etc.) and outside border. Similar as using SetNextWindowBgAlpha(0.0f).
ImGuiWindowFlags_HorizontalScrollbar=1<<11,// Allow horizontal scrollbar to appear (off by default). You may use SetNextWindowContentSize(ImVec2(width,0.0f)); prior to calling Begin() to specify width. Read code in imgui_demo in the "Horizontal Scrolling" section.
ImGuiWindowFlags_NoBringToFrontOnFocus=1<<13,// Disable bringing window to front when taking focus (e.g. clicking on it or programmatically giving it focus)
ImGuiWindowFlags_NoNavInputs=1<<16,// No gamepad/keyboard navigation within the window
ImGuiWindowFlags_NoNavFocus=1<<17,// No focusing toward this window with gamepad/keyboard navigation (e.g. skipped by CTRL+TAB)
ImGuiWindowFlags_UnsavedDocument=1<<18,// Display a dot next to the title. When used in a tab/docking context, tab is selected when clicking the X + closure is not assumed (will wait for user to stop submitting the tab). Otherwise closure is assumed when pressing the X, so if you keep submitting the tab may reappear at end of tab bar.
ImGuiWindowFlags_NavFlattened=1<<23,// [BETA] On child window: share focus scope, allow gamepad/keyboard navigation to cross over parent border to this child or between sibling child windows.
// - May be combined with SetNextWindowSizeConstraints() to set a min/max size for each axis (see "Demo->Child->Auto-resize with Constraints").
// - Size measurement for a given axis is only performed when the child window is within visible boundaries, or is just appearing.
// - This allows BeginChild() to return false when not within boundaries (e.g. when scrolling), which is more optimal. BUT it won't update its auto-size while clipped.
// While not perfect, it is a better default behavior as the always-on performance gain is more valuable than the occasional "resizing after becoming visible again" glitch.
// - You may also use ImGuiChildFlags_AlwaysAutoResize to force an update even when child window is not in view.
// HOWEVER PLEASE UNDERSTAND THAT DOING SO WILL PREVENT BeginChild() FROM EVER RETURNING FALSE, disabling benefits of coarse clipping.
ImGuiChildFlags_AlwaysUseWindowPadding=1<<1,// Pad with style.WindowPadding even if no border are drawn (no padding by default for non-bordered child windows because it makes more sense)
ImGuiChildFlags_AlwaysAutoResize=1<<6,// Combined with AutoResizeX/AutoResizeY. Always measure size even when child is hidden, always return true, always disable clipping optimization! NOT RECOMMENDED.
ImGuiChildFlags_FrameStyle=1<<7,// Style the child window like a framed item: use FrameBg, FrameRounding, FrameBorderSize, FramePadding instead of ChildBg, ChildRounding, ChildBorderSize, WindowPadding.
ImGuiInputTextFlags_EnterReturnsTrue=1<<5,// Return 'true' when Enter is pressed (as opposed to every time the value was modified). Consider looking at the IsItemDeactivatedAfterEdit() function.
ImGuiInputTextFlags_CallbackCompletion=1<<6,// Callback on pressing TAB (for completion handling)
ImGuiInputTextFlags_CallbackHistory=1<<7,// Callback on pressing Up/Down arrows (for history handling)
ImGuiInputTextFlags_CallbackAlways=1<<8,// Callback on each iteration. User code may query cursor position, modify text buffer.
ImGuiInputTextFlags_CallbackCharFilter=1<<9,// Callback on character inputs to replace or discard them. Modify 'EventChar' to replace or discard, or return 1 in callback to discard.
ImGuiInputTextFlags_CtrlEnterForNewLine=1<<11,// In multi-line mode, unfocus with Enter, add new line with Ctrl+Enter (default is opposite: unfocus with Ctrl+Enter, add line with Enter).
ImGuiInputTextFlags_NoUndoRedo=1<<16,// Disable undo/redo. Note that input text owns the text data while active, if you want to provide your own undo/redo stack you need e.g. to call ClearActiveID().
ImGuiInputTextFlags_CallbackResize=1<<18,// Callback on buffer capacity changes request (beyond 'buf_size' parameter value), allowing the string to grow. Notify when the string wants to be resized (for string types which hold a cache of their Size). You will be provided a new BufSize in the callback and NEED to honor it. (see misc/cpp/imgui_stdlib.h for an example of using this)
ImGuiInputTextFlags_CallbackEdit=1<<19,// Callback on any edit (note that InputText() already returns true on edit, the callback is useful mainly to manipulate the underlying buffer while focus is active)
ImGuiInputTextFlags_EscapeClearsAll=1<<20,// Escape key clears content if not empty, and deactivate otherwise (contrast to default behavior of Escape to revert)
ImGuiTreeNodeFlags_NoAutoOpenOnLog=1<<4,// Don't automatically and temporarily open node when Logging is active (by default logging will automatically open tree nodes)
ImGuiTreeNodeFlags_OpenOnArrow=1<<7,// Only open when clicking on the arrow part. If ImGuiTreeNodeFlags_OpenOnDoubleClick is also set, single-click arrow or double-click all box to open.
ImGuiTreeNodeFlags_FramePadding=1<<10,// Use FramePadding (even for an unframed text node) to vertically align text baseline to regular widget height. Equivalent to calling AlignTextToFramePadding().
ImGuiTreeNodeFlags_SpanAvailWidth=1<<11,// Extend hit box to the right-most edge, even if not framed. This is not the default in order to allow adding other items on the same line without using AllowOverlap mode.
ImGuiTreeNodeFlags_SpanFullWidth=1<<12,// Extend hit box to the left-most and right-most edges (cover the indent area).
ImGuiTreeNodeFlags_SpanTextWidth=1<<13,// Narrow hit box + narrow hovering highlight, will only cover the label text.
ImGuiTreeNodeFlags_SpanAllColumns=1<<14,// Frame will span all columns of its container table (text will still fit in current column)
ImGuiTreeNodeFlags_NavLeftJumpsBackHere=1<<15,// (WIP) Nav: left direction may move to this TreeNode() from any of its child (items submitted between TreeNode and TreePop)
//ImGuiTreeNodeFlags_NoScrollOnOpen = 1 << 16, // FIXME: TODO: Disable automatic scroll on TreePop() if node got just open and contents is not visible
ImGuiPopupFlags_MouseButtonLeft=0,// For BeginPopupContext*(): open on Left Mouse release. Guaranteed to always be == 0 (same as ImGuiMouseButton_Left)

ImGuiPopupFlags_MouseButtonMiddle=2,// For BeginPopupContext*(): open on Middle Mouse release. Guaranteed to always be == 2 (same as ImGuiMouseButton_Middle)
ImGuiPopupFlags_NoReopen=1<<5,// For OpenPopup*(), BeginPopupContext*(): don't reopen same popup if already open (won't reposition, won't reinitialize navigation)
//ImGuiPopupFlags_NoReopenAlwaysNavInit = 1 << 6, // For OpenPopup*(), BeginPopupContext*(): focus and initialize navigation even when not reopening.
ImGuiPopupFlags_NoOpenOverExistingPopup=1<<7,// For OpenPopup*(), BeginPopupContext*(): don't open if there's already a popup at the same level of the popup stack
ImGuiPopupFlags_NoOpenOverItems=1<<8,// For BeginPopupContextWindow(): don't return true when hovering items, only when hovering empty space
ImGuiPopupFlags_AnyPopupId=1<<10,// For IsPopupOpen(): ignore the ImGuiID parameter and test for any popup.
ImGuiPopupFlags_AnyPopupLevel=1<<11,// For IsPopupOpen(): search/test at any level of the popup stack (default test in the current level)
ImGuiComboFlags_PopupAlignLeft=1<<0,// Align the popup toward the left by default
ImGuiComboFlags_HeightSmall=1<<1,// Max ~4 items visible. Tip: If you want your combo popup to be a specific size you can use SetNextWindowSizeConstraints() prior to calling BeginCombo()
ImGuiComboFlags_HeightRegular=1<<2,// Max ~8 items visible (default)
ImGuiComboFlags_HeightLarge=1<<3,// Max ~20 items visible
ImGuiComboFlags_HeightLargest=1<<4,// As many fitting items as possible
ImGuiTabBarFlags_NoCloseWithMiddleMouseButton=1<<3,// Disable behavior of closing tabs (that are submitted with p_open != NULL) with middle mouse button. You may handle this behavior manually on user's side with if (IsItemHovered() && IsMouseClicked(2)) *p_open = false.
ImGuiTabItemFlags_NoCloseWithMiddleMouseButton=1<<2,// Disable behavior of closing tabs (that are submitted with p_open != NULL) with middle mouse button. You may handle this behavior manually on user's side with if (IsItemHovered() && IsMouseClicked(2)) *p_open = false.
ImGuiTabItemFlags_NoPushId=1<<3,// Don't call PushID()/PopID() on BeginTabItem()/EndTabItem()
ImGuiTabItemFlags_NoAssumedClosure=1<<8,// Tab is selected when trying to close + closure is not immediately assumed (will wait for user to stop submitting the tab). Otherwise closure is assumed when pressing the X, so if you keep submitting the tab may reappear at end of tab bar.
ImGuiFocusedFlags_ChildWindows=1<<0,// Return true if any children of the window is focused
ImGuiFocusedFlags_RootWindow=1<<1,// Test from root window (top most parent of the current hierarchy)
ImGuiFocusedFlags_AnyWindow=1<<2,// Return true if any window is focused. Important: If you are trying to tell how to dispatch your low-level inputs, do NOT use this. Use 'io.WantCaptureMouse' instead! Please read the FAQ!
ImGuiFocusedFlags_NoPopupHierarchy=1<<3,// Do not consider popup hierarchy (do not treat popup emitter as parent of popup) (when used with _ChildWindows or _RootWindow)
//ImGuiFocusedFlags_DockHierarchy = 1 << 4, // Consider docking hierarchy (treat dockspace host as parent of docked window) (when used with _ChildWindows or _RootWindow)
// Note: if you are trying to check whether your mouse should be dispatched to Dear ImGui or to your app, you should use 'io.WantCaptureMouse' instead! Please read the FAQ!
ImGuiHoveredFlags_None=0,// Return true if directly over the item/window, not obstructed by another window, not obstructed by an active popup or modal blocking inputs under them.
ImGuiHoveredFlags_NoPopupHierarchy=1<<3,// IsWindowHovered() only: Do not consider popup hierarchy (do not treat popup emitter as parent of popup) (when used with _ChildWindows or _RootWindow)
//ImGuiHoveredFlags_DockHierarchy = 1 << 4, // IsWindowHovered() only: Consider docking hierarchy (treat dockspace host as parent of docked window) (when used with _ChildWindows or _RootWindow)

ImGuiHoveredFlags_NoNavOverride=1<<11,// IsItemHovered() only: Disable using gamepad/keyboard navigation state when active, always query mouse
// - typically used in IsItemHovered() + SetTooltip() sequence.
// - this is a shortcut to pull flags from 'style.HoverFlagsForTooltipMouse' or 'style.HoverFlagsForTooltipNav' where you can reconfigure desired behavior.
// e.g. 'TooltipHoveredFlagsForMouse' defaults to 'ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort'.
// - for frequently actioned or hovered items providing a tooltip, you want may to use ImGuiHoveredFlags_ForTooltip (stationary + delay) so the tooltip doesn't show too often.
ImGuiHoveredFlags_Stationary=1<<13,// Require mouse to be stationary for style.HoverStationaryDelay (~0.15 sec) _at least one time_. After this, can move on same item/window. Using the stationary test tends to reduces the need for a long delay.
ImGuiHoveredFlags_DelayNone=1<<14,// IsItemHovered() only: Return true immediately (default). As this is the default you generally ignore this.
ImGuiHoveredFlags_DelayShort=1<<15,// IsItemHovered() only: Return true after style.HoverDelayShort elapsed (~0.15 sec) (shared between items) + requires mouse to be stationary for style.HoverStationaryDelay (once per item).
ImGuiHoveredFlags_DelayNormal=1<<16,// IsItemHovered() only: Return true after style.HoverDelayNormal elapsed (~0.40 sec) (shared between items) + requires mouse to be stationary for style.HoverStationaryDelay (once per item).
ImGuiHoveredFlags_NoSharedDelay=1<<17,// IsItemHovered() only: Disable shared delay system where moving from one item to the next keeps the previous timer for a short time (standard for tooltips with long delays)
ImGuiDragDropFlags_SourceNoPreviewTooltip=1<<0,// Disable preview tooltip. By default, a successful call to BeginDragDropSource opens a tooltip so you can display a preview or description of the source contents. This flag disables this behavior.
ImGuiDragDropFlags_SourceNoDisableHover=1<<1,// By default, when dragging we clear data so that IsItemHovered() will return false, to avoid subsequent user code submitting tooltips. This flag disables this behavior so you can still call IsItemHovered() on the source item.
ImGuiDragDropFlags_SourceNoHoldToOpenOthers=1<<2,// Disable the behavior that allows to open tree nodes and collapsing header by holding over them while dragging a source item.
ImGuiDragDropFlags_SourceAllowNullID=1<<3,// Allow items such as Text(), Image() that have no unique identifier to be used as drag source, by manufacturing a temporary identifier based on their window-relative position. This is extremely unusual within the dear imgui ecosystem and so we made it explicit.
ImGuiDragDropFlags_SourceExtern=1<<4,// External source (from outside of dear imgui), won't attempt to read current item/window info. Will always return true. Only one Extern source can be active simultaneously.
ImGuiDragDropFlags_SourceAutoExpirePayload=1<<5,// Automatically expire the payload if the source cease to be submitted (otherwise payloads are persisting while being dragged)
ImGuiDragDropFlags_AcceptBeforeDelivery=1<<10,// AcceptDragDropPayload() will returns true even before the mouse button is released. You can then call IsDelivery() to test if the payload needs to be delivered.
ImGuiDragDropFlags_AcceptNoDrawDefaultRect=1<<11,// Do not draw the default highlight rectangle when hovering over target.
ImGuiDragDropFlags_AcceptPeekOnly=ImGuiDragDropFlags_AcceptBeforeDelivery|ImGuiDragDropFlags_AcceptNoDrawDefaultRect,// For peeking ahead and inspecting the payload before delivery.
// The keyboard key enum values are named after the keys on a standard US keyboard, and on other keyboard types the keys reported may not match the keycaps.

ImGuiInputFlags_RouteFocused=1<<11,// Route to windows in the focus stack (DEFAULT). Deep-most focused window takes inputs. Active item takes inputs over deep-most focused window.
ImGuiInputFlags_RouteGlobal=1<<12,// Global route (unless a focused window or active item registered the route).
ImGuiInputFlags_RouteAlways=1<<13,// Do not register route, poll keys directly.
ImGuiInputFlags_RouteOverFocused=1<<14,// Option: global route: higher priority than focused route (unless active item in focused route).
ImGuiInputFlags_RouteOverActive=1<<15,// Option: global route: higher priority than active item. Unlikely you need to use that: will interfere with every active items, e.g. CTRL+A registered by InputText will be overridden by this. May not be fully honored as user/internal code is likely to always assume they can access keys when active.
ImGuiInputFlags_RouteUnlessBgFocused=1<<16,// Option: global route: will not be applied if underlying background/void is focused (== no Dear ImGui windows are focused). Useful for overlay applications.
ImGuiConfigFlags_NavEnableSetMousePos=1<<2,// Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward. Will update io.MousePos and set io.WantSetMousePos=true. If enabled you MUST honor io.WantSetMousePos requests in your backend, otherwise ImGui will react as if the mouse is jumping around back and forth.
ImGuiConfigFlags_NoMouse=1<<4,// Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information set by the backend.
ImGuiConfigFlags_NoMouseCursorChange=1<<5,// Instruct backend to not alter mouse cursor shape and visibility. Use if the backend cursor changes are interfering with yours and you don't want to use SetMouseCursor() to change mouse cursor. You may want to honor requests from imgui by reading GetMouseCursor() yourself instead.
// User storage (to allow your backend/engine to communicate to code that may be shared between multiple projects. Those flags are NOT used by core Dear ImGui)
ImGuiBackendFlags_HasGamepad=1<<0,// Backend Platform supports gamepad and currently has one connected.
ImGuiBackendFlags_HasMouseCursors=1<<1,// Backend Platform supports honoring GetMouseCursor() value to change the OS cursor shape.
ImGuiBackendFlags_HasSetMousePos=1<<2,// Backend Platform supports io.WantSetMousePos requests to reposition the OS mouse position (only used if ImGuiConfigFlags_NavEnableSetMousePos is set).
ImGuiBackendFlags_RendererHasVtxOffset=1<<3,// Backend Renderer supports ImDrawCmd::VtxOffset. This enables output of large meshes (64K+ vertices) while still using 16-bit indices.
// - When changing this enum, you need to update the associated internal table GStyleVarInfo[] accordingly. This is where we link enum values to members offset/type.
ImGuiColorEditFlags_NoSmallPreview=1<<4,// // ColorEdit, ColorPicker: disable color square preview next to the inputs. (e.g. to show only the inputs)

ImGuiColorEditFlags_Float=1<<24,// [DataType] // ColorEdit, ColorPicker, ColorButton: _display_ values formatted as 0.0f..1.0f floats instead of 0..255 integers. No round-trip of value via integers.
ImGuiSliderFlags_AlwaysClamp=1<<4,// Clamp value to min/max bounds when input manually with CTRL+Click. By default CTRL+Click allows going out of bounds.
ImGuiSliderFlags_Logarithmic=1<<5,// Make the widget logarithmic (linear otherwise). Consider using ImGuiSliderFlags_NoRoundToFormat with this if using a format-string with small amount of digits.
ImGuiSliderFlags_NoRoundToFormat=1<<6,// Disable rounding underlying value to match precision of the display format string (e.g. %.3f values are rounded to those 3 digits)
ImGuiSliderFlags_InvalidMask_=0x7000000F,// [Internal] We treat using those bits as being potentially a 'float power' argument from the previous API that has got miscast to this enum, and will trigger an assert if needed.

ImGuiMouseSource_Pen,// Input is coming from a pressure/magnetic pen (often used in conjunction with high-sampling rates).
// Important: Treat as a regular enum! Do NOT combine multiple values using binary operators! All the functions above treat 0 as a shortcut to ImGuiCond_Always.
// - Fixed Columns can be enlarged as needed. Table will show a horizontal scrollbar if needed.
// - When using auto-resizing (non-resizable) fixed columns, querying the content width to use item right-alignment e.g. SetNextItemWidth(-FLT_MIN) doesn't make sense, would create a feedback loop.
// - Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
// If you specify a value for 'inner_width' then effectively the scrolling space is known and Stretch or mixed Fixed/Stretch columns become meaningful again.

// - You generally do NOT need to care or use this ever. But we need to make it available in imgui.h because some of our public structures are relying on it.
// - We use std-like naming convention here, which is a little unusual for this codebase.
// - Important: clear() frees memory, resize(0) keep the allocated buffer. We use resize(0) a lot to intentionally recycle allocated buffers across frames and amortize our costs.
// - Important: our implementation does NOT call C++ constructors/destructors, we treat everything as raw data! This is intentional but be extra mindful of that,
// Do NOT use this class as a std::vector replacement in your own code! Many of the structures used by dear imgui can be safely initialized by a zero-memset.

floatWindowRounding;// Radius of window corners rounding. Set to 0.0f to have rectangular windows. Large values tend to lead to variety of artifacts and are not recommended.
floatWindowBorderSize;// Thickness of border around windows. Generally set to 0.0f or 1.0f. (Other values are not well tested and more CPU/GPU costly).
floatChildBorderSize;// Thickness of border around child windows. Generally set to 0.0f or 1.0f. (Other values are not well tested and more CPU/GPU costly).
floatPopupRounding;// Radius of popup window corners rounding. (Note that tooltip windows use WindowRounding)
floatPopupBorderSize;// Thickness of border around popup/tooltip windows. Generally set to 0.0f or 1.0f. (Other values are not well tested and more CPU/GPU costly).
ImVec2TouchExtraPadding;// Expand reactive bounding box for touch-based system where touch position is not accurate enough. Unfortunately we don't sort widgets so priority on overlap will always be given to the first widget. So don't grow this too much!
floatTabMinWidthForCloseButton;// Minimum width for close button to appear on an unselected tab when hovered. Set to 0.0f to always show when hovering, set to FLT_MAX to never show close button unless selected.
ImVec2SelectableTextAlign;// Alignment of selectable text. Defaults to (0.0f, 0.0f) (top-left aligned). It's generally important to keep this left-aligned if you want to lay multiple items on a same line.
floatSeparatorTextBorderSize;// Thickkness of border in SeparatorText()
ImVec2SeparatorTextAlign;// Alignment of text within the separator. Defaults to (0.0f, 0.5f) (left aligned, center).
ImVec2SeparatorTextPadding;// Horizontal offset of text from each edge of the separator + spacing on other axis. Generally small values. .y is recommended to be == FramePadding.y.
ImVec2DisplayWindowPadding;// Apply to regular windows: amount which we enforce to keep visible when moving near edges of your screen.
ImVec2DisplaySafeAreaPadding;// Apply to every windows, menus, popups, tooltips: amount where we avoid displaying contents. Adjust if you cannot see the edges of your screen (e.g. on a TV where scaling has not been configured).
floatMouseCursorScale;// Scale software rendered mouse cursor (when io.MouseDrawCursor is enabled). We apply per-monitor DPI scaling over this scale. May be removed later.
boolAntiAliasedLines;// Enable anti-aliased lines/borders. Disable if you are really tight on CPU/GPU. Latched at the beginning of the frame (copied to ImDrawList).
boolAntiAliasedLinesUseTex;// Enable anti-aliased lines/borders using textures where possible. Require backend to render with bilinear filtering (NOT point/nearest filtering). Latched at the beginning of the frame (copied to ImDrawList).
boolAntiAliasedFill;// Enable anti-aliased edges around filled shapes (rounded rectangles, circles, etc.). Disable if you are really tight on CPU/GPU. Latched at the beginning of the frame (copied to ImDrawList).
floatCurveTessellationTol;// Tessellation tolerance when using PathBezierCurveTo() without a specific number of segments. Decrease for highly tessellated curves (higher quality, more polygons), increase to reduce quality.
floatCircleTessellationMaxError;// Maximum error (in pixels) allowed when using AddCircle()/AddCircleFilled() or drawing rounded corner rectangles with no explicit segment count specified. Decrease for higher quality but more geometry.
ImGuiHoveredFlagsHoverFlagsForTooltipMouse;// Default flags when using IsItemHovered(ImGuiHoveredFlags_ForTooltip) or BeginItemTooltip()/SetItemTooltip() while using mouse.

IMGUI_APIvoidSetAppAcceptingEvents(boolaccepting_events);// Set master flag for accepting key/mouse/text events (default to true). Useful if you have native dialog boxes that are interrupting your application loop/refresh, and you want to disable events being queued while your app is frozen.
IMGUI_APIvoidClearEventsQueue();// Clear all incoming events.
IMGUI_APIvoidClearInputKeys();// Clear current keyboard/mouse/gamepad state + current frame text input buffer. Equivalent to releasing all keys/buttons.
boolWantCaptureMouse;// Set when Dear ImGui will use mouse inputs, in this case do not dispatch them to your main game/application (either way, always pass on mouse inputs to imgui). (e.g. unclicked mouse is hovering over an imgui window, widget is active, mouse was clicked over an imgui window, etc.).
boolWantCaptureKeyboard;// Set when Dear ImGui will use keyboard inputs, in this case do not dispatch them to your main game/application (either way, always pass keyboard inputs to imgui). (e.g. InputText active, or an imgui window is focused and navigation is enabled, etc.).
boolWantTextInput;// Mobile/console: when set, you may display an on-screen keyboard. This is set by Dear ImGui when it wants textual keyboard input to happen (e.g. when a InputText widget is active).
boolWantSetMousePos;// MousePos has been altered, backend should reposition mouse on next frame. Rarely used! Set only when ImGuiConfigFlags_NavEnableSetMousePos flag is enabled.
boolWantSaveIniSettings;// When manual .ini load/save is active (io.IniFilename == NULL), this will be set to notify your application that you can call SaveIniSettingsToMemory() and save yourself. Important: clear io.WantSaveIniSettings yourself after saving!
boolNavActive;// Keyboard/Gamepad navigation is currently allowed (will handle ImGuiKey_NavXXX events) = a window is focused and it doesn't use the ImGuiWindowFlags_NoNavInputs flag.
boolNavVisible;// Keyboard/Gamepad navigation is visible and allowed (will handle ImGuiKey_NavXXX events).
floatFramerate;// Estimate of application framerate (rolling average over 60 frames, based on io.DeltaTime), in frame per second. Solely for convenience. Slow applications may not want to use a moving average or may want to reset underlying buffers occasionally.
intMetricsRenderVertices;// Vertices output during last call to Render()
intMetricsRenderIndices;// Indices output during last call to Render() = number of triangles * 3
intMetricsRenderWindows;// Number of visible windows
intMetricsActiveWindows;// Number of active windows
ImVec2MouseDelta;// Mouse delta. Note that this is zero if either current or previous position are invalid (-FLT_MAX,-FLT_MAX), so a disappearing/reappearing mouse won't have a huge delta.
boolMouseDown[5];// Mouse buttons: 0=left, 1=right, 2=middle + extras (ImGuiMouseButton_COUNT == 5). Dear ImGui mostly uses left and right buttons. Other buttons allow us to track if the mouse is being used by your application + available to user as a convenience via IsMouse** API.
floatMouseWheel;// Mouse wheel Vertical: 1 unit scrolls about 5 lines text. >0 scrolls Up, <0 scrolls Down. Hold SHIFT to turn vertical scroll into horizontal scroll.
floatMouseWheelH;// Mouse wheel Horizontal. >0 scrolls Left, <0 scrolls Right. Most users don't have a mouse with a horizontal wheel, may not be filled by all backends.
ImGuiKeyChordKeyMods;// Key mods flags (any of ImGuiMod_Ctrl/ImGuiMod_Shift/ImGuiMod_Alt/ImGuiMod_Super flags, same as io.KeyCtrl/KeyShift/KeyAlt/KeySuper but merged into flags. Read-only, updated by NewFrame()
boolWantCaptureMouseUnlessPopupClose;// Alternative to WantCaptureMouse: (WantCaptureMouse == true && WantCaptureMouseUnlessPopupClose == false) when a click over void is expected to close a popup.
ImVec2MousePosPrev;// Previous mouse position (note that MouseDelta is not necessary == MousePos-MousePosPrev, in case either position is invalid)
ImVec2MouseClickedPos[5];// Position at time of clicking
doubleMouseClickedTime[5];// Time of last click (used to figure out double-click)
boolMouseClicked[5];// Mouse button went from !Down to Down (same as MouseClickedCount[x] != 0)
boolMouseDoubleClicked[5];// Has mouse button been double-clicked? (same as MouseClickedCount[x] == 2)
ImU16MouseClickedCount[5];// == 0 (not clicked), == 1 (same as MouseClicked[]), == 2 (double-clicked), == 3 (triple-clicked) etc. when going from !Down to Down
ImU16MouseClickedLastCount[5];// Count successive number of clicks. Stays valid after mouse release. Reset after another click is done.
boolMouseReleased[5];// Mouse button went from Down to !Down
boolMouseDownOwned[5];// Track if button was clicked inside a dear imgui window or over void blocked by a popup. We don't request mouse capture from the application if click started outside ImGui bounds.
boolMouseWheelRequestAxisSwap;// On a non-Mac system, holding SHIFT requests WheelY to perform the equivalent of a WheelX event. On a Mac system this is already enforced by the system.
// Legacy: before 1.87, we required backend to fill io.KeyMap[] (imgui->native map) during initialization and io.KeysDown[] (native indices) every frame.
// This is still temporarily supported as a legacy feature. However the new preferred scheme is for backend to call io.AddKeyEvent().

#ifndef IMGUI_DISABLE_OBSOLETE_KEYIO
intKeyMap[ImGuiKey_COUNT];// [LEGACY] Input: map of indices into the KeysDown[512] entries array which represent your "native" keyboard state. The first 512 are now unused and should be kept zero. Legacy backend will write into KeyMap[] using ImGuiKey_ indices which are always >512.
boolKeysDown[ImGuiKey_COUNT];// [LEGACY] Input: Keyboard keys that are pressed (ideally left in the "native" order your engine has access to keyboard keys, so you can use your own defines/enums for keys). This used to be [512] sized. It is now ImGuiKey_COUNT to allow legacy io.KeysDown[GetKeyIndex(...)] to work without an overflow.
floatNavInputs[ImGuiNavInput_COUNT];// [LEGACY] Since 1.88, NavInputs[] was removed. Backends from 1.60 to 1.86 won't build. Feed gamepad inputs via io.AddKeyEvent() and ImGuiKey_GamepadXXX enums.

// - ImGuiInputTextFlags_CallbackAlways: Callback on each iteration
// - ImGuiInputTextFlags_CallbackCompletion: Callback on pressing TAB
// - ImGuiInputTextFlags_CallbackHistory: Callback on pressing Up/Down arrows
// - ImGuiInputTextFlags_CallbackCharFilter: Callback on character inputs to replace or discard them. Modify 'EventChar' to replace or discard, or return 1 in callback to discard.
// - During Resize callback, Buf will be same as your input buffer.
// - However, during Completion/History/Always callback, Buf always points to our own internal data (it is not the same as your buffer)! Changes to it will be reflected into your own buffer shortly after the callback.
// - To modify the text buffer in a callback, prefer using the InsertChars() / DeleteChars() function. InsertChars() will take care of calling the resize callback if necessary.
// - If you know your edits are not going to resize the underlying buffer allocation, you may modify the contents of 'Buf[]' directly. You need to update 'BufTextLen' accordingly (0 <= BufTextLen < BufSize) and set 'BufDirty'' to true so InputText can update its internal state.
ImWcharEventChar;// Character input // Read-write // [CharFilter] Replace character with another one, or set to zero to drop. return 1 is equivalent to setting EventChar=0;

intBufSize;// Buffer size (in bytes) = capacity+1 // Read-only // [Resize,Completion,History,Always] Include zero-terminator storage. In C land == ARRAYSIZE(my_char_array), in C++ land: string.capacity()+1
boolBufDirty;// Set if you modify Buf/BufTextLen! // Write // [Completion,History,Always]
// Helper: Execute a block of code at maximum once a frame. Convenient if you want to quickly create a UI within deep-nested code that runs multiple times every frame.
// We use it to e.g. store collapse state for a tree (Int 0/1)
// This is optimized for efficient lookup (dichotomy into a contiguous buffer) and rare insertion (typically tied to user interactions aka max once a frame)
// - References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.
// - A typical use case where this is convenient for quick hacking (e.g. add storage during a live Edit&Continue session if you can't modify existing struct)
// - Clipper can measure the height of the first element
// - Clipper calculate the actual range of elements to display based on the current clipping rectangle, position the cursor before the first visible element.
// items_count: Use INT_MAX if you don't know how many items you have (in which case the cursor won't be advanced in the final step)
// items_height: Use -1.0f to be calculated automatically on first step. Otherwise pass in the distance between your items, typically GetTextLineHeightWithSpacing() or GetFrameHeightWithSpacing().
// Call IncludeItemByIndex() or IncludeItemsByIndex() *BEFORE* first call to Step() if you need a range of items to not be clipped, regardless of their visibility.
// - It is important that we are keeping those disabled by default so they don't leak in user space.
// - This is in order to allow user enabling implicit cast operators between ImVec2/ImVec4 and their own types (using IM_VEC2_CLASS_EXTRA in imconfig.h)
// - You can use '#define IMGUI_DEFINE_MATH_OPERATORS' to import our operators, provided as a courtesy.
// **Avoid storing ImColor! Store either u32 of ImVec4. This is not a full-featured color class. MAY OBSOLETE.
// **None of the ImGui API are using ImColor directly but you can use it as a convenience to pass colors in either ImU32 or ImVec4 formats. Explicitly cast to ImU32 or ImVec4 if needed.
// The expected behavior from your rendering function is 'if (cmd.UserCallback != NULL) { cmd.UserCallback(parent_list, cmd); } else { RenderTriangles() }'
// If you want to override the signature of ImDrawCallback, you can simply use e.g. '#define ImDrawCallback MyDrawCallback' (in imconfig.h) + update rendering backend accordingly.
// This is useful, for example, if you submitted callbacks which you know have altered the render state and you want it to be restored.
// Render state is not reset by default because they are many perfectly useful way of altering render state (e.g. changing shader/blending settings before an Image call).
ImVec4ClipRect;// 4*4 // Clipping rectangle (x1, y1, x2, y2). Subtract ImDrawData->DisplayPos to get clipping rectangle in "viewport" coordinates
ImTextureIDTextureId;// 4-8 // User-provided texture ID. Set by user in ImfontAtlas::SetTexID() for fonts or passed to Image*() functions. Ignore if never using images or multiple fonts atlas.

// You can override the vertex format layout by defining IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT in imconfig.h
// The code expect ImVec2 pos (8 bytes), ImVec2 uv (8 bytes), ImU32 col (4 bytes), but you can re-order them or add other fields as needed to simplify integration in your engine.
// The type has to be described within the macro (you can either declare the struct or use a typedef). This is because ImVec2/ImU32 are likely not declared at the time you'd want to set your type up.
// NOTE: IMGUI DOESN'T CLEAR THE STRUCTURE AND DOESN'T CALL A CONSTRUCTOR SO ANY CUSTOM FIELD WILL BE UNINITIALIZED. IF YOU ADD EXTRA FIELDS (SUCH AS A 'Z' COORDINATES) YOU WILL NEED TO CLEAR THEM DURING RENDER OR TO IGNORE THEM.
ImDrawFlags_RoundCornersTopLeft=1<<4,// AddRect(), AddRectFilled(), PathRect(): enable rounding top-left corner only (when rounding > 0.0f, we default to all corners). Was 0x01.

ImDrawFlags_RoundCornersNone=1<<8,// AddRect(), AddRectFilled(), PathRect(): disable rounding on all corners (when rounding > 0.0f). This is NOT zero, NOT an implicit flag!
ImDrawListFlags_AntiAliasedLines=1<<0,// Enable anti-aliased lines/borders (*2 the number of triangles for 1.0f wide line or lines thin enough to be drawn using textures, otherwise *3 the number of triangles)
ImDrawListFlags_AntiAliasedLinesUseTex=1<<1,// Enable anti-aliased lines/borders using textures when possible. Require backend to render with bilinear filtering (NOT point/nearest filtering).
// In single viewport mode, top-left is == GetMainViewport()->Pos (generally 0,0), bottom-right is == GetMainViewport()->Pos+Size (generally io.DisplaySize).
// You are totally free to apply whatever transformation matrix to want to the data (depending on the use of the transformation you may want to apply it to ClipRect as well!)
// Important: Primitives are always added to the list and not culled (culling is done at higher-level by ImGui:: functions), if you use this API a lot consider coarse culling your drawn objects.
// If you want to create ImDrawList instances, pass them ImGui::GetDrawListSharedData() or create and use your own ImDrawListSharedData (so you can use ImDrawList without ImGui)
IMGUI_APIvoidPushClipRect(constImVec2&clip_rect_min,constImVec2&clip_rect_max,boolintersect_with_current_clip_rect=false);// Render-level scissoring. This is passed down to your render function but not used for CPU-side coarse clipping. Prefer using higher-level ImGui::PushClipRect() to affect logic (hit-testing and widget culling)
// - Filled shapes must always use clockwise winding order. The anti-aliasing fringe depends on it. Counter-clockwise shapes will have "inward" anti-aliasing.
// - "p_min" and "p_max" represent the upper-left and lower-right corners of the rectangle.
// - "uv_min" and "uv_max" represent the normalized texture coordinates to use for those corners. Using (0,0)->(1,1) texture coordinates will generally display the entire texture.
// - Important: filled shapes must always use clockwise winding order! The anti-aliasing fringe depends on it. Counter-clockwise shapes will have "inward" anti-aliasing.
// so e.g. 'PathArcTo(center, radius, PI * -0.5f, PI)' is ok, whereas 'PathArcTo(center, radius, PI, PI * -0.5f)' won't have correct anti-aliasing when followed by PathFillConvex().
IMGUI_APIvoidAddCallback(ImDrawCallbackcallback,void*callback_data);// Your rendering function must check for 'UserCallback' in ImDrawCmd and call the function instead of rendering triangles.
IMGUI_APIvoidAddDrawCmd();// This is useful if you need to forcefully create a new draw call (to allow for dependent rendering / blending). Otherwise primitives are merged into the same draw-call as much as possible
// - Use to split render into layers. By switching channels to can render out-of-order (e.g. submit FG primitives before BG primitives)
// - Use to minimize draw calls (e.g. if going back-and-forth between multiple clipping rectangles, prefer to append into separate channels then merge at the end)

ImVec2DisplayPos;// Top-left position of the viewport to render (== top-left of the orthogonal projection matrix to use) (== GetMainViewport()->Pos for the main viewport, == (0.0) in most single-viewport applications)
ImVec2DisplaySize;// Size of the viewport to render (== GetMainViewport()->Size for the main viewport, == io.DisplaySize in most single-viewport applications)
ImVec2FramebufferScale;// Amount of pixels for each unit of DisplaySize. Based on io.DisplayFramebufferScale. Generally (1,1) on normal display, (2,2) on OSX with Retina display.
ImGuiViewport*OwnerViewport;// Viewport carrying the ImDrawData instance, might be of use to the renderer (generally not).
IMGUI_APIvoidDeIndexAllBuffers();// Helper to convert all buffers from indexed to non-indexed, in case you cannot render indexed. Note: this is slow and most likely a waste of resources. Always prefer indexed rendering!
IMGUI_APIvoidScaleClipRects(constImVec2&fb_scale);// Helper to scale the ClipRect field of each ImDrawCmd. Use if your final output buffer is at a different scale than Dear ImGui expects, or if there is a difference between your window resolution and framebuffer resolution.
intOversampleH;// 2 // Rasterize at higher quality for sub-pixel positioning. Note the difference between 2 and 3 is minimal. You can reduce this to 1 for large glyphs save memory. Read https://github.com/nothings/stb/blob/master/tests/oversample/README.md for details.
intOversampleV;// 1 // Rasterize at higher quality for sub-pixel positioning. This is not really useful as we don't use sub-pixel positions on the Y axis.
boolPixelSnapH;// false // Align every glyph to pixel boundary. Useful e.g. if you are merging a non-pixel aligned font with the default font. If enabled, you can set OversampleH/V to 1.
ImVec2GlyphExtraSpacing;// 0, 0 // Extra spacing (in pixels) between glyphs. Only X axis is supported for now.
ImVec2GlyphOffset;// 0, 0 // Offset all glyphs from this font input.

boolMergeMode;// false // Merge into previous ImFont, so you can combine multiple inputs font into one ImFont (e.g. ASCII font + icons + Japanese glyphs). You may want to use GlyphOffset.y when merge font of different heights.
floatRasterizerMultiply;// 1.0f // Linearly brighten (>1.0f) or darken (<1.0f) font output. Brightening small fonts may be a good workaround to make them more readable. This is a silly thing we may remove in the future.
floatRasterizerDensity;// 1.0f // DPI scale for rasterization, not altering other font metrics: make it easy to swap between e.g. a 100% and a 400% fonts for a zooming display. IMPORTANT: If you increase this it is expected that you increase font scale accordingly, otherwise quality may look lowered.
ImWcharEllipsisChar;// -1 // Explicitly specify unicode codepoint of ellipsis character. When fonts are being merged first specified ellipsis will be used.
unsignedintColored:1;// Flag to indicate glyph is colored and should generally ignore tinting (make it usable with no shift on little-endian as this is used in loops)
unsignedintVisible:1;// Flag to indicate glyph has no visible pixels (e.g. space). Allow early out when rendering.
IMGUI_APIvoidAddText(constchar*text,constchar*text_end=NULL);// Add string (each character of the UTF-8 string are added)

IMGUI_APIvoidBuildRanges(ImVector<ImWchar>*out_ranges);// Output new ranges
ImFontAtlasFlags_NoBakedLines=1<<2,// Don't build thick line textures into the atlas (save a little texture memory, allow support for point/nearest filtering). The AntiAliasedLinesUseTex features uses them, otherwise they will be rendered using polygons (more expensive for CPU/GPU).
// atlas is build (when calling GetTexData*** or Build()). We only copy the pointer, not the data.

ImTextureIDTexID;// User data to refer to the texture once it has been uploaded to user's graphic systems. It is passed back to you during rendering via the ImDrawCmd structure.
intTexDesiredWidth;// Texture width desired by user before Build(). Must be a power-of-two. If have many glyphs your graphics API have texture size restrictions you may want to increase texture width to decrease height.
intTexGlyphPadding;// Padding between glyphs within texture in pixels. Defaults to 1. If your rendering method doesn't rely on bilinear filtering you may set this to 0 (will also need to set AntiAliasedLinesUseTex = false).

ImVector<float>IndexAdvanceX;// 12-16 // out // // Sparse. Glyphs->AdvanceX in a directly indexable way (cache-friendly for CalcTextSize functions which only this this info, and are often bottleneck in large UI).
shortConfigDataCount;// 2 // in // ~ 1 // Number of ImFontConfig involved in creating this font. Bigger than 1 when merging multiple font sources into one ImFont.
intMetricsTotalSurface;// 4 // out // // Total surface in pixels to get an idea of the font rasterization/texture cost (not exact, we approximate the cost of padding between glyphs)
ImU8Used4kPagesMap[(IM_UNICODE_CODEPOINT_MAX+1)/4096/8];// 2 bytes if ImWchar=ImWchar16, 34 bytes if ImWchar==ImWchar32. Store 1-bit for each block of 4K codepoints that has one active glyph. This is mainly used to facilitate iterations across all used codepoints.
