MacOs doesn't open in fullscreen

[freesig]

If you call

    let window_id = app
        .new_window()
        .with_fullscreen(true)
        .view(view)
        .build()
        .unwrap();

It just opens up maximized.
I'm not sure if this happens on other OS.

It fullscreens correctly on X11 Linux I believe.

Does it fullscreen properly on macos when you use Cmd+F? That calls set_fullscreen under the hood if the window is already created.

I'd imagine there would be an issue for this in winit as we pretty much just call the winit methods directly under the hood.

Yep you can get to fullscreen with Cmd+F. I'll have a dig into this when I get a chance. It crashes though due to the segfault bug.

let mon = app.main_window().current_monitor();
app.main_window().set_fullscreen(Some(mon));

This works actually. I think maybe it just needs the MonitorId

@freesig is there a way to start the app in fullscreen immediately? This is sort of a chicken and egg problem, you need the MonitorId to create a window with with_fullscreen (not set_fullscreen after the fact), but the only way I've found to get MonitorId is if I already have a window. 😆

This wouldn't be that important if window resizing worked on macOS, but it is currently unusable due to #372. So at the moment, no fullscreen windows on macOS.
