[Qemu-devel] [PATCH] gtk: implement -full-screen and -no-frame

[Peter Wu]

Aiming for GTK as replacement for SDL, features like -full-screen and -no-frame
should also be implemented.

Bringing the window into full-screen mode is done by faking activating the full
screen menu item with a NULL menu item (which currently is not used by
gd_menu_full_screen). This is done after showing the windows to make the cursor
and menu hidden.
