Debug Tools

(work in progress) Also see Tips.

Metrics/Debugger window

Many internal state and tools are exposed in the Metrics window. To access the Metrics window:

• Call ShowMetricsWindow().
• Or from the Demo window you can find it in the Tools menu. They will help you understand how Dear ImGui works, and can help you diagnose problems.

Some of the debug tools

Debug Log

Stack Tool

https://github.com/ocornut/imgui/issues/4631

Item Picker

https://github.com/ocornut/imgui/issues/2673

The Item Picker will allow you to pick an item with the mouse and have Dear ImGui break within the call-stack of that item. This is useful if you have large UI / codebase and you would to easily find out where some UI item is emitted. You can find it in Metrics>Tools>Item Picker. Also see #2673.
