Class

GdkDisplay

Description [src]

final class Gdk.Display : GObject.Object {
  /* No available fields */
}

GdkDisplay objects are the GDK representation of a workstation.

Their purpose are two-fold:

  • To manage and provide information about input devices (pointers, keyboards, etc)
  • To manage and provide information about output devices (monitors, projectors, etc)

Most of the input device handling has been factored out into separate GdkSeat objects. Every display has a one or more seats, which can be accessed with gdk_display_get_default_seat() and gdk_display_list_seats().

Output devices are represented by GdkMonitor objects, which can be accessed with gdk_display_get_monitor_at_surface() and similar APIs.
