How to get window size to scale panels accordingly.

[rik-rosseel]

I would like to make an app with a side panel and a main panel. I'm trying to get the side panel to be a percentage of the entire window (e.g.: 20% of window width). How would I be able to get the window size to make the sidepanel bigger or smaller if the window is resized?

After some more digging not knowing where to look I stumbled on the answer: The winow size is under frame.info().window_info.size.

What is the answer with the newer version of egui an eframe ?

try out ctx.input(|i| i.viewport().outer_rect)?

I was able to get the size of the window with ctx.input(|i: &egui::InputState| i.screen_rect())

@emilk is there any advantage to ctx.input(|i: &egui::InputState| i.screen_rect()) vs just ctx.screen_rect()?
