Class

GdkEvent

Description [src]

abstract class Gdk.Event : GObject.TypeInstance {
  /* No available fields */
}

GdkEvents are immutable data structures, created by GDK to represent windowing system events.

In GTK applications the events are handled automatically by toplevel widgets and passed on to the event controllers of appropriate widgets, so using GdkEvent and its related API is rarely needed.
