Re: Going fullscreen and back

Why not use gtk_window_fullscreen? I've only tried it on a Gnome
desktop, it works well.

Hi there,

 The small working code below shows
 how my app goes fullscreen and back.

 1) Is there a better way of doing this?

 2) This code works fine in Enlightenment,
 KDE, BlackBox, IceWM, etc. In Gnome and XFCE
 it works, but the desktop bars are still visible
 (I suppose it should be possible to change this?).

 However, in GNOME and only in GNOME, I have to
 subtract 1 pixel, on width or height, for this to work.
 In other words, if I replace this:

 gdk_window_move_resize (window->window,
 0, 0, gdk_screen_width (), gdk_screen_height () - 1);

 by this:
 gdk_window_move_resize (window->window,
 0, 0, gdk_screen_width (), gdk_screen_height ());

 poor Gnome WM gets confused, indeed goes fullscreen,
 but does not come back... :-(

 What is the best way to handle this?
 going fullscreen is a very useful feature
 in many scientific/engineering apps.

 Many thanks,
