ImGui is designed to enable fast iteration and empower programmers to create content creation tools and visualization/ debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and thus lacks certain features normally found in more high-level libraries.

ImGui outputs vertex buffers and simple command-lists that you can render in your application. The number of draw calls and state changes is typically very small. Because it doesn't know or touch graphics state directly, you can call ImGui commands anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate ImGui with your existing codebase.

_A common misunderstanding is that some people think immediate mode gui == immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes, as the gui functions as called by the user. Some lazy IMGUI-style librairies may work this way but this is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are rather optimal and you can render them later, in your app or even remotely._

ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, etc.

_NB: those third-party bindings may be more or less maintained, more or less close to the spirit of original API. People who create language bindings sometimes haven't used the C++ API themselves. ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, always check the original C++ version first!_

Integrating Dear ImGui within your custom engine is a matter of wiring mouse/keyboard inputs and providing a render function that can bind a texture and render simple textured triangles. The examples/ folder is populated with applications doing just that. If you are an experienced programmer it should take you less than an hour to integrate Dear ImGui in your custom engine, but make sure to spend time reading the FAQ, the comments and other documentation!

<b>Which version should I get?</b>
|
||||||
|
|
||||||
|
I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master. The library is fairly stable and regressions tend to be fixed fast when reported. You may also want to checkout the [navigation branch](https://github.com/ocornut/imgui/tree/navigation) if you want to use Dear ImGui with a gamepad (it is also possible to map keyboard inputs to some degree). The Navigation branch is being kept up to date with Master.

The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.

I recommend using [Synergy](http://synergy-project.org) ([sources](https://github.com/symless/synergy)). In particular, the _src/micro/uSynergy.c_ file contains a small client that you can use on any platform to connect to your host PC. You can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate.

Yes. I have written data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools).

ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Many programmers have unfortunately been taught by their environment to make unnecessarily complicated things. ImGui is about making things that are simple, efficient and powerful.

Probably fast enough for most uses. Down to the foundation of its visual design, ImGui is engineered to be fairly performant both in term of CPU and GPU usage. Running elaborate code and creating elaborate UI will of course have a cost but ImGui aims to minimize it.

Mileage may vary but the following screenshot can give you a rough idea of the cost of running and rendering UI code (In the case of a trivial demo application like this one, your driver/os setup are likely to be the bottleneck. Testing performance as part of a real application is recommended).

If you intend to display large lists of items (say, 1000+) it can be beneficial for your code to perform clipping manually - one way is using helpers such as ImGuiListClipper - in order to avoid submitting them to ImGui in the first place. Even though ImGui will discard your clipped items it still needs to calculate their size and that overhead will add up if you have thousands of items. If you can handle clipping and height positionning yourself then browsing a list with millions of items isn't a problem.

You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface.

ImGui takes advantage of a few C++ features for convenience but nothing anywhere Boost-insanity/quagmire. In particular, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience but could be removed.

Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.

There is an unofficial but reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly. I would suggest using your target language functionality to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. It was really designed with C++ in mind and may not make the same amount of sense with another language. Also see [Links](https://github.com/ocornut/imgui/wiki/Links) for third-party bindings to other languages.

ISSUES & TODO LIST
|
||||||
|
|
||||||
|
Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues/XXXX
|
||||||
|
The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point they usually exist on the github issue tracker).
|
||||||
|
It's mostly a bunch of personal notes, probably incomplete. Feel free to query if you have any questions.
|
||||||
|
|
||||||
|
- doc/test: add a proper documentation+regression testing system (#435)
|
||||||
|
- doc/test: checklist app to verify binding/integration of imgui (test inputs, rendering, callback, etc.).
|
||||||
|
- doc/tips: tips of the day: website? applet in imgui_club?
|
||||||
|
- project: folder or separate repository with maintained helpers (e.g. imgui_memory_editor.h, imgui_stl.h, maybe imgui_dock would be there?)
|
||||||
|
|
||||||
|
- window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
|
||||||
|
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
|
||||||
|
- window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
|
||||||
|
- window: allow resizing of child windows (possibly given min/max for each axis?.)
|
||||||
|
- window: background options for child windows, border option (disable rounding).
|
||||||
|
- window: resizing from any sides? done. > need backends to honor mouse cursors properly. (#822)
|
||||||
|
- window: resize from borders: support some form of outer padding to make it easier to grab borders. (#822)
|
||||||
|
- window: begin with *p_open == false should return false.
|
||||||
|
- window: get size/pos helpers given names (see discussion in #249)
|
||||||
|
- window: a collapsed window can be stuck behind the main menu bar?
|
||||||
|
- window: when window is very small, prioritize resize button over close button.
|
||||||
|
- window: detect extra End() call that pop the "Debug" window out and assert at End() call site instead of at end of frame.
|
||||||
|
- window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd.
|
||||||
|
- window: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
|
||||||
|
- window: expose contents size. (#1045)
|
||||||
|
- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
|
||||||
|
- window: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate.
|
||||||
|
!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
|
||||||
|
- scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
|
||||||
|
|
||||||
|
- drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
|
||||||
|
- drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
|
||||||
|
- drawlist: primtiives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api
|
||||||
|
- drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
|
||||||
|
- drawlist: non-AA strokes have gaps between points (#593, #288), especially RenderCheckmark().
|
||||||
|
- drawlist: would be good to be able to deep copy a draw list (ImVector= op?).
|
||||||
|
- drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
|
||||||
|
|
||||||
|
- main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them.
|
||||||
|
- main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering.
|
||||||
|
- main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
|
||||||
|
- main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
|
||||||
|
- main: rename the main "Debug" window to avoid ID collision with user who may want to use "Debug" with specific flags.
|
||||||
|
|
||||||
|
- widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395)
|
||||||
|
- widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
|
||||||
|
- widgets: add visauls for Disabled/ReadOnly mode and expose publicly (#211)
|
||||||
|
- widgets: add always-allow-overlap mode.
|
||||||
|
- widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
|
||||||
|
- widgets: activate by identifier (trigger button, focus given id)
|
||||||
|
|
||||||
|
- input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile.
|
||||||
|
- input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
|
||||||
|
- input text: expose CursorPos in char filter event (#816)
|
||||||
|
- input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return NULL if not active.
|
||||||
|
- input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
|
||||||
|
- input text: way to dynamically grow the buffer without forcing the user to initially allocate for worse case, e.g. more natural std::string (follow up on #200)
|
||||||
|
- input text: hover tooltip could show unclamped text
|
||||||
|
- input text: option to Tab after an Enter validation.
|
||||||
|
- input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
|
||||||
|
- input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
|
||||||
|
- input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
|
||||||
|
- input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependant). actually a very old bug but no one appears to have noticed it.
|
||||||
|
- input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
|
||||||
|
- input text multi-line: support for cut/paste without selection (cut/paste the current line)
|
||||||
|
- input text multi-line: line numbers? status bar? (follow up on #200)
|
||||||
|
- input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
|
||||||
|
- input text multi-line: better horizontal scrolling support (#383, #1224)
|
||||||
|
- input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
|
||||||
|
- input number: optional range min/max for Input*() functions
|
||||||
|
- input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
|
||||||
|
- input number: use mouse wheel to step up/down
|
||||||
|
- input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
|
||||||
|
|
||||||
|
- layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner.
|
||||||
|
- layout: generalization of the above: a concept equivalent to word processor ruler tab stop ~ mini columns (position in X, no clipping implied) (vaguely relate to #267, #395, also what is used internally for menu items)
|
||||||
|
- layout: horizontal layout helper (#97)
|
||||||
|
- layout: horizontal flow until no space left (#404)
|
||||||
|
- layout: more generic alignment state (left/right/centered) for single items?
|
||||||
|
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
|
||||||
|
- layout: BeginGroup() needs a border option. (~#1496)
|
||||||
|
- layout: vertical alignement of mixed height items (e.g. buttons) within a same line (#1284)
|
||||||
|
|
||||||
|
- columns: sizing policy (e.g. for each column: fixed size, %, fill, distribute default size among fills) (#513, #125)
|
||||||
|
- columns: add a conditional parameter to SetColumnOffset() (#513, #125)
|
||||||
|
- columns: headers. reorderable. (#513, #125)
|
||||||
|
- columns: optional sorting modifiers (up/down), sort list so sorting can be done multi-critera. notify user when sort order changed.
|
||||||
|
- columns: option to alternate background colors on odd/even scanlines.
|
||||||
|
- columns: allow columns to recurse.
|
||||||
|
- columns: allow a same columns set to be interrupted by e.g. CollapsingHeader and resume with columns in sync when moving them.
|
||||||
|
- columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (#125)
|
||||||
|
- columns: flag to add horizontal separator above/below?
|
||||||
|
- columns/layout: setup minimum line height (equivalent of automatically calling AlignFirstTextHeightToWidgets)
|
||||||
|
|
||||||
|
!- color: the color conversion helpers/types are a mess and needs sorting out.
|
||||||
|
- color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h
|
||||||
|
- coloredit: it is still somehow awkward to copy colors around (unless going through Hex mode).
|
||||||
|
|
||||||
|
- plot: full featured plot/graph api w/ scrolling, zooming etc. all bell & whistle. why not!
|
||||||
|
- plot: PlotLines() should use the polygon-stroke facilities, less verticles (currently issues with averaging normals)
|
||||||
|
- plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
|
||||||
|
- plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
|
||||||
|
- plot: option/feature: draw the zero line
|
||||||
|
- plot: option/feature: draw grid, vertical markers
|
||||||
|
- plot: option/feature: draw unit
|
||||||
|
- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
|
||||||
|
|
||||||
|
- clipper: ability to force display 1 item in the list would be convenient (for patterns where we need to set active id etc.)
|
||||||
|
- clipper: ability to disable the clipping through a simple flag/bool.
|
||||||
|
- clipper: ability to run without knowing full count in advance.
|
||||||
|
|
||||||
|
- splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
|
||||||
|
|
||||||
|
- dock: docking extension
|
||||||
|
- dock: dock out from a collapsing header? would work nicely but need emitting window to keep submitting the code.
|
||||||
|
|
||||||
|
- tabs: re-ordering, close buttons, context menu, persistent order (#261, #351)
|
||||||
|
|
||||||
|
- ext: stl-ish friendly extension (imgui_stl.h) that has wrapped for std::string, std::vector etc.
|
||||||
|
|
||||||
|
- button: provide a button that looks framed.
|
||||||
|
- image/image button: misalignment on padded/bordered button?
|
||||||
|
- image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
|
||||||
|
- image button: not taking an explicit id is odd.
|
||||||
|
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
|
||||||
|
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
|
||||||
|
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
|
||||||
|
- slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
|
||||||
|
- slider: precision dragging
|
||||||
|
- slider: step option (#1183)
|
||||||
|
- knob: rotating knob widget (#942)
|
||||||
|
- slider & drag: int data passing through a float
|
||||||
|
- drag float: up/down axis
|
||||||
|
- drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
|
||||||
|
|
||||||
|
- combo: use clipper: make it easier to disable clipper with a single flag.
|
||||||
|
- combo: option for BeginCombo to not return true when unchanged (#1182)
|
||||||
|
- combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
|
||||||
|
- listbox: multiple selection.
|
||||||
|
- listbox: unselect option (#1208)
|
||||||
|
- listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (wip stash)
|
||||||
|
- listbox: user may want to initial scroll to focus on the one selected value?
|
||||||
|
- listbox: expose hovered item for a basic ListBox
|
||||||
|
- listbox: keyboard navigation.
|
||||||
|
- listbox: scrolling should track modified selection.
|
||||||
|
|
||||||
|
!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
|
||||||
|
- popups: reopening context menu at new position should be the behavior by default? (equivalent to internal OpenPopupEx() with reopen_existing=true) (~#1497)
|
||||||
|
- popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331)
|
||||||
|
- popups: clicking outside (to close popup) and holding shouldn't drag window below.
|
||||||
|
- popups: add variant using global identifier similar to Begin/End (#402)
|
||||||
|
- popups: border options. richer api like BeginChild() perhaps? (#197)
|
||||||
|
- tooltip: tooltip that doesn't fit in entire screen seems to lose their "last preferred direction" and may teleport when moving mouse.
|
||||||
|
- tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
|
||||||
|
- tooltip: allow tooltips with timers? or general timer policy? (instaneous vs timed)
|
||||||
|
|
||||||
|
- menus: calling BeginMenu() twice with a same name doesn't append as Begin() does for regular windows (#1207)
|
||||||
|
- statusbar: add a per-window status bar helper similar to what menubar does.
|
||||||
|
- shortcuts: local-style shortcut api, e.g. parse "&Save"
|
||||||
|
- shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
|
||||||
|
- shortcuts: programmatically access shortcuts "Focus("&Save"))
|
||||||
|
- menus: menubars: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
|
||||||
|
- menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer.
|
||||||
|
|
||||||
|
- text: selectable text (for copy) as a generic feature (ItemFlags?)
|
||||||
|
- text: proper alignment options in imgui_internal.h
|
||||||
|
- text wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
|
||||||
|
- text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
|
||||||
|
- text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
|
||||||
|
|
||||||
|
- tree node / optimization: avoid formatting when clipped.
|
||||||
|
- tree node: tree-node/header right-most side doesn't take account of horizontal scrolling.
|
||||||
|
- tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
|
||||||
|
- tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
|
||||||
|
- tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
|
||||||
|
- tree node: tweak color scheme to distinguish headers from selected tree node (#581)
|
||||||
|
- tree node: leaf/non-leaf highlight mismatch.
|
||||||
|
|
||||||
|
!- settings: expose enough to save/load .ini from RAM instead of fopen
|
||||||
|
- settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
|
||||||
|
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)
|
||||||
|
- stb: add defines to disable stb implementations
|
||||||
|
|
||||||
|
!- style: better default styles. (#707)
|
||||||
|
- style: border types: out-screen, in-screen, etc. (#447)
|
||||||
|
- style/optimization: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding.
|
||||||
|
- style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier)
|
||||||
|
- style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
|
||||||
|
- style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
|
||||||
|
- style: global scale setting.
|
||||||
|
- style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle
|
||||||
|
- style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223)
|
||||||
|
- style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
|
||||||
|
- style editor: color child window height expressed in multiple of line height.
|
||||||
|
|
||||||
|
- log: LogButtons() options for specifying depth and/or hiding depth slider
|
||||||
|
- log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
|
||||||
|
- log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
|
||||||
|
- log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
|
||||||
|
|
||||||
|
- filters: set a current filter that tree node can automatically query to hide themselves
|
||||||
|
- filters: handle wildcards (with implicit leading/trailing *), regexps
|
||||||
|
- filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
|
||||||
|
|
||||||
|
- drag and drop: add demo. (#143, #479)
|
||||||
|
- drag and drop: test with reordering nodes (in a list, or a tree node). (#143)
|
||||||
|
- drag and drop: test integrating with os drag and drop.
|
||||||
|
- node/graph editor (#306)
|
||||||
|
- pie menus patterns (#434)
|
||||||
|
- markup: simple markup language for color change? (#902)
|
||||||
|
|
||||||
|
- font: better vertical centering (based e.g on height of lowercase 'x'?). currently Roboto-Medium size 16 px isn't currently centered.
|
||||||
|
- font: free the Alpha buffer if user only requested RGBA.
|
||||||
|
!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
|
||||||
|
- font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX
|
||||||
|
- font: finish CustomRectRegister() to allow mapping unicode codepoint to custom texture data
|
||||||
|
- font: PushFontSize API (#1018)
|
||||||
|
- font/atlas: incremental updates
|
||||||
|
- font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
|
||||||
|
- font/atlas: allow user to submit its own primitive to be rectpacked, and allow to map them on a Unicode point.
|
||||||
|
- font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
|
||||||
|
- font/text: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
|
||||||
|
- font: imgui_freetype.h alternative renderer (#618)
|
||||||
|
- font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct).
|
||||||
|
- font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
|
||||||
|
- font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
|
||||||
|
- font: fix AddRemapChar() to work before font has been built.
|
||||||
|
- font: (api breaking) removed "TTF" from symbol names. also because it now supports OTF.
|
||||||
|
|
||||||
|
!- nav/keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing.
|
||||||
|
- nav: integrate navigation branch into master. (#787)
|
||||||
|
- nav: integrate/design keyboard controls.
|
||||||
|
- nav: once tab should go through most/all widgets (in submission order?)
|
||||||
|
- nav: currently cannot access menubar of a child window with Alt/menu key.
|
||||||
|
- nav: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys.
|
||||||
|
- focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
|
||||||
|
- focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
|
||||||
|
- focus: unable to use SetKeyboardFocusHere() on clipped widgets. (#787)
|
||||||
|
- inputs: rework IO system to be able to pass actual ordered/timestamped events. use an event queue? (~#335, #71)
|
||||||
|
- inputs: allow to pass explicit double-clicks if that's the only thing the user's backend can get them. (e.g. for windows by the CS_DBLCLKS style).
|
||||||
|
- inputs: support track pad style scrolling & slider edit.
|
||||||
|
|
||||||
|
- misc: idle refresh: expose cursor blink animation timer for backend to be able to lower framerate.
|
||||||
|
- misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags (Why?)
|
||||||
|
- misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
|
||||||
|
- misc: fix for compilation settings where stdcall isn't the default (e.g. vectorcall) (#1230)
|
||||||
|
- remote: make a system like RemoteImGui first-class citizen/project (#75)
|
||||||
|
|
||||||
|
- natvis: more the imgui.natvis file in a better location. perhaps reorganize extra_fonts/? (#1569)
|
||||||
|
|
||||||
|
- demo: add vertical separator demo
|
||||||
|
- demo: add virtual scrolling example?
|
||||||
|
- examples: directx9: save/restore device state more thoroughly.
|
||||||
|
- examples: window minimize, maximize (#583)
|
||||||
|
- examples: provide a zero-framerate/idle example.
|
||||||
|
- examples: glfw: could go idle when minimized? if (glfwGetWindowAttrib(window, GLFW_ICONIFIED)) { glfwWaitEvents(); continue; } // the problem is that DeltaTime will be super high on resume, perhaps provide a way to let impl know (#440)
|
||||||
|
- optimization: replace vsnprintf with stb_printf? or enable the defines/infrastructure to allow it (#1038)
|
||||||
|
- optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
|
||||||
|
- optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
|
||||||
|
- optimization: use another hash function than crc32, e.g. FNV1a
|
||||||
|
- optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
|
||||||
|
- optimization: turn some the various stack vectors into statically-sized arrays

SDL2 + OpenGL example (legacy, fixed pipeline).

This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
|
||||||
|
If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
|
||||||
|
complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
|
||||||
|
confuse your GPU driver.

The pre-C++11 version has the values directly encoded as utf-8:

FREETYPE RASTERIZER, SMALL FONT SIZES
|
||||||
|
---------------------------------------
|
||||||
|
|
||||||
|
Dear Imgui uses stb_truetype.h to rasterize fonts (with optional oversampling).
|
||||||
|
This technique and implementation are not ideal for fonts rendered at _small sizes_, which may appear a little blurry.
|
||||||
|
There is an implementation of the ImFontAtlas builder using FreeType that you can use:
|
||||||
|
|
||||||
|
https://github.com/ocornut/imgui_club
|
||||||
|
|
||||||
|
FreeType supports auto-hinting which tends to improve the readability of small fonts.
|
||||||
|
Note that this code currently creates textures that are unoptimally too large (could be fixed with some work)
|
||||||
|
|
||||||
|
|
||||||
|
---------------------------------------
|
||||||
|
BUILDING CUSTOM GLYPH RANGES
|
||||||
|
---------------------------------------
|
||||||
|
|
||||||
|
You can use the ImFontAtlas::GlyphRangesBuilder helper to create glyph ranges based on text input.
|
||||||
|
For exemple: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
|
||||||
|
|
||||||
|
ImVector<ImWchar> ranges;
|
||||||
|
ImFontAtlas::GlyphRangesBuilder builder;
|
||||||
|
builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
|
||||||
|
builder.AddChar(0x7262); // Add a specific character
|
||||||
|
builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
|
||||||
|
builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
|
||||||
|
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);
