Maximizing the application? Works fine for me on Ubuntu. Is it a Windows issue?

[sla-te]

Maximizing a window inside the rendered window using the internal window system which allows to drag a window into the middle to maximize it. Yes on Windows.

Take a look at this screencast:

I pushed the example to: https://github.com/chwba/concur_gui_test/blob/847d94a4d85271131023d2435a9c23d1698e6e39/src/features/nice_feature/nice_feature_gui.py#L59

Thanks for the information. I was able to reproduce. I already had a similiar issue in the past, but I can't remember what was the cause. Will investigate.

perhaps related to ocornut/imgui#2286

Caused by nested windows (ocornut/imgui#2109 (comment)). You shouldn't really nest windows, since the code inside a window is only executed when the window is open. This leads to a feedback loop:

1. Window is rendered, which causes a nested window to be rendered
2. The nested window displays in a tab, which hides the parent window
3. Parent window doesn't render because it's hidden. This causes the child window to disappear.
4. The parent window is now visible again, and it is rendered.

That's the reason the docs for window say they can't be nested. I will add this issue to the docs & faq.

EDIT: I will push the changes after your PR is merged.

Alright, great, ill push the final ammendmends as discussed in the PR in a bit.

Updated docs. Closing.

Can you implement & push a workaround for this problem according to what how it is currently implemented here: https://github.com/chwba/concur_gui_test/blob/847d94a4d85271131023d2435a9c23d1698e6e39/src/features/nice_feature/nice_feature_gui.py#L59
