There was // no standard way of doing it until recently. ICCCM doesn't know the // concept of fullscreen windows and the only way to make a window // fullscreen is to remove decorations, resize it to cover entire screen // and set WIN_LAYER_ABOVE_DOCK. // // This doesn't always work, though. Specifically, at least kwin from // KDE 3 ignores the hint. The only way to make kwin accept our request // is to emulate the way Qt does it. That is, unmap the window, set // _NET_WM_WINDOW_TYPE to _KDE_NET_WM_WINDOW_TYPE_OVERRIDE (KDE extension), // add _NET_WM_STATE_STAYS_ON_TOP (ditto) to _NET_WM_STATE and map // the window again. // // Version 1.2 of Window Manager Specification (aka wm-spec aka // Extended Window Manager Hints) introduced _NET_WM_STATE_FULLSCREEN // window state which provides cleanest and simplest possible way of // making a window fullscreen. WM-spec is a de-facto standard adopted // by GNOME and KDE folks, but _NET_WM_STATE_FULLSCREEN isn't yet widely // supported. As of January 2003, only GNOME 2's default WM Metacity // implements, KDE will support it from version 3.2.
