GTK window hints

Question

I'm trying to get a window to cover the whole screen. Its positioning and dimensions is fine but it gets covered by the Gnome panel. To complicate things I have two monitors and this app needs to support people with multiple screens.

WINDOW_TYPE_HINT_SPLASHSCREEN is a good start. It covers both screens but not the panel. It's still there, just behind the panel.

WINDOW_TYPE_HINT_DOCK looked ideal but I need this window to take focus to listen to a keyboard event. _DOCK seems like it purposely ignores keyboard events (which kind of makes sense). Can I force it to take keyboard focus?

Is there some way I can force a hinted window to cover the panel?

Answer 1

There's window.fullscreen() which you can call on a normal "un-hinted" window. I assume this lets the window manager decide whether the window should cover the panel or not.
