Detailed Description

GdkScreen objects are the GDK representation of a physical screen. It is used throughout GDK and GTK+ to specify which screen the top level windows are to be displayed on. It is also used to query the screen specification and default settings such as the default colormap (gdkScreenGetDefaultColormap), the screen width (gdkScreenGetWidth), etc. Note that a screen may consist of multiple monitors which are merged to form a large screen area.
