Expose Window maximize API

[stefnotch]

I'm using Slint for a fullscreen/maximized overlay.

For that, I would love it if https://docs.rs/slint/latest/slint/struct.Window.html gained functionality equivalent to one of those two options

• https://docs.rs/winit/latest/winit/window/struct.Window.html#method.set_maximized
• https://docs.rs/winit/latest/winit/window/struct.Window.html#method.set_fullscreen

There's the somewhat related https://github.com/slint-ui/slint/issues/333 issue, but it seems rather outdated. So I figured I'd make a specific feature request instead.

My tooling

• Window 10
• Rust

Agreed. In the meantime, what you can use as workaround is to depend on i-slint-backend-winit and use WinitWindowAccessor, if you're using the winit backend.

Closing this as a duplicate of #3283

@tronical Maximize is not the same as fullscreen though

On the other hand, I don't know how much of the Window API we really want to abstract/duplicate in our own API instead of just exposing winit directly

Yes, I know it's not the same. I do think that this goes hand-in-hand implementation wise.
