CustomBackground callback [python]

[kutraj87]

Firstly, thanks a lot for a wonderful framework pthom!

I've been using imgui_bundle (python) for an OpenGL based rendering project. I've been trying to port my application to use hello_imgui for incorporating docking splits. I'm trying to do this with an FBO inside a DockableWindow and using imgui::Image(). I'm having issues with the max_content_size inside this window so the OpenGL texture is getting cropped (story for another thread perhaps?)

For this reason, I found the CustomBackground callback - it looks like it will exactly solve my particular use-case! Instead of rendering to a separate FBO, I can just render to the default framebuffer ("background window"). Please let me know if I've misunderstood this. I have tried using the background draw lists feature in imgui but I keep getting weird clipping issues.

I noticed that the CustomBackground callback is mentioned in the hello_imgui_api.md file. Just curious about your plans for incorporating this into imgui-bundle python bindings.

Thanks again!

Hello, and thanks for your kind words!

The CustomBackground callback is brand new (yesterday!) and was not added into ImGui Bundle yet. It was added now:

see https://pthom.github.io/imgui_bundle/quickstart.html#_custom_3d_background

I hope this helps!

Many thanks! This is exactly what was needed. Works like a charm :)
