e.g. "##Foobar" display an empty label and uses "##Foobar" as ID
|
||||
- read articles about the imgui principles (see web links) to understand the requirement and use of ID.
|
||||
|
||||
- tip: the construct 'if (IMGUI_ONCE_UPON_A_FRAME)' will evaluate to true only once a frame, you can use it to add custom UI in the middle of a deep nested inner loop in your code.
|
||||
- tip: the construct 'static ImGuiOnceUponAFrame once; if (once)' will evaluate to 'true' only once a frame, you can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
|
||||
- tip: you can call Render() multiple times (e.g for VR renders), up to you to communicate the extra state to your RenderDrawListFn function.
|
||||
- tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
|
||||
- tip: read the ShowTestWindow() code for more example of how to use ImGui!
