### Visual debugging
|

|
||||
You can use ImDrawList primitives on the foreground drawlist, e.g. `GetForegroundDrawList()->AddRectFilled(...)` to bypass clipping of the current window. Whenever you are working with coordinates, consider displaying it on screen using `AddRect()`, `AddCircle()`, etc.
|
||||
- `ImGui::DebugDrawCursorPos()`, `ImGui::DebugDrawItemRect()` are a convenient way to easily display the current layout position or previous item geometry.

- You can use ImDrawList primitives on the foreground drawlist, e.g. `GetForegroundDrawList()->AddRectFilled(...)` to bypass clipping of the current window. Whenever you are working with coordinates and unsure of their values, consider displaying them on screen using `AddRect()`, `AddCircle()`, etc.

|

- Using keyboard modifiers is a convenient way to easily enable/disable something.

```cpp
|

ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
|
||||
ImVec2 my_pos= ImGui::GetCursorScreenPos();
|
||||
|
||||
if (ImGui::GetIO().KeyShift)
|
||||
{
|
||||
ImGui::DebugDrawItemRect(); // Helper to draw a rectangle between GetItemRectMin() and GetItemRectMax()
|
||||
ImGui::GetForegroundDrawList()->AddCircleFilled(my_pos, 3, IM_COL32(255, 0, 0, 255)); // Draw red circle at position
|
||||
}
|
||||
ImGui::Text("Shift held: %d", ImGui::GetIO().KeyShift);
|
||||
```
