How do I disable auto-resize for a window?

[kotx]

I want my window to be fixed-sized, but the user should be able to resize it manually. Ideally the fixed-size window should fit all widgets in it.

Isn't that the default behaviour?
Just enable scrolling for window.

No, it's not- unless this

egui/egui_demo_lib/src/apps/demo/tests.rs

Line 424 in 9603bb4

// ui.heading("Some additional text here, that should also be visible"); // this works, but messes with the resizing a bit

is a bug. It might be.

Can you explain a bit more? "Fixed size" and "resizable" are opposites - you can only have one.

I mean that egui shouldn't resize it, but I want users to be able to resize it.

.resizable(true) should do it, IF the contents allow resizing. If the content is a single button, the window will still shrink to the size of that button.

Check out the "Window Resize" demo at https://emilk.github.io/egui/ - the source code is at https://github.com/emilk/egui/blob/master/egui_demo_lib/src/apps/demo/tests.rs#L386-L461

Yeah but it seems I'm having the same issue as here

egui/egui_demo_lib/src/apps/demo/tests.rs

Line 424 in 9603bb4

// ui.heading("Some additional text here, that should also be visible"); // this works, but messes with the resizing a bit

where the window snaps sizes to the scroll view.

That's not a bug, but a consequence/limitation of immediate mode. The ScrollArea must be the last thing in the window for auto-resizing it to work, unless you use panels like in egui_demo_lib/src/apps/demo/window_with_panels.rs

[kotx]

So would it be possible to have the window be auto-sized initially, but never auto-size to the ScrollArea after?
