Version: 1.3-current
The FLTK window method fullscreen() does not do what most people refers to
as "fullscreen". A fullscreen should cover the "full" screen, completely
hide any other application and OS widget. The current FLTK implementation
basically puts up what can be described as a maximized window without
borders. It also lacks in terms of functionality: The applications
currently needs to keep track of the non-fullscreen coordinates and the
fullscreen state. If the X WM initiates the fullscreen mode (possible with
EWMH window managers), the app is not notified and it's internal state is
out of sync.
The attached patch adds a complete (to my knowledge) full screen support
for all platforms, even multi monitor systems. It requires the patch in
#2640.
A few comments about the patch:
* A new API: fullscreen_off() without arguments
* A new API: fullscreen_active(), to request the current fullscreen state
* A new event: FL_FULLSCREEN
* The X11 implementation supports EWMH but falls back to
override_redirect+grab.
The "fullscreen" test application has also been modified somewhat:
* It uses the FL_FULLSCREEN event to properly track the fullscreen state
* It provides an input field, to allow for testing that the input focus
works correctly
* It uses the fullscreen_off() function without arguments
