[Feature Request] Maintain aspect ratio of floating windows when resizing

[borosai]

I feel the current behavior is the correct default behavior: resize floating windows freely. However, in certain situations it would be nice to be able to resize a floating window while maintaining its aspect ratio (in my case, video content).

Without getting into the implementation (which I don't understand anyway), something like this would be ideal (only mouse related):
super + button3 -> resize freely (current behavior)
super + shift + button3 -> resize while maintaining aspect ratio

Honestly, this would be a nice enhancement to see, but it's not important since I currently just resize carefully to eliminate the black bars. Still, if it's not too much of a pain to implement, it would be great.

Would be nice - for example i3 resizes mpv proportionally by default (no idea how).

if you have honor_size_hints on then windows should resize based on their hints. mpv for instance would act as described. above.

otherwise you can use wmutils to mimic the behavior; either by a keybind that resizes based on current size and a multiplier(+1/10,*2,etc).
or by subscribing to pointer_action and watching for, say, resize_corner, capturing the size at begin and resizing one dimension to match the original ratio at end.

honor_size_hints works for mpv (it's bspc config honor_size_hints true in config)

@ortango
Thanks for the tips. honor_size_hints is something I always disable because I prefer my windows to be tiled evenly, so I hadn't considered this setting as a way to deal with resizing these specific windows.

I'll focus on the methods you've mentioned, and I suppose it's fine to close this issue.

i don't know if you happened to see this PR come in, but it seems like exactly what you would like: #1251
