|
* #GdkScreen objects are the GDK representation of the screen on
|
|
* which windows can be displayed and on which the pointer moves.
|
|
* X originally identified screens with physical screens, but
|
|
* nowadays it is more common to have a single #GdkScreen which
|
|
* combines several physical monitors (see gdk_screen_get_n_monitors()).
|
|
*
|
|
* GdkScreen is used throughout GDK and GTK+ to specify which screen
|
|
* the top level windows are to be displayed on.
