Event

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.

Constructors

this this(GdkEvent* gdkEvent, bool ownedRef): Sets our main struct and passes it to the parent class.

Destructor

~this ~this(): Undocumented in source.

Members

Aliases

doref alias doref = ref_: Undocumented in source.

Functions

GetAngle bool GetAngle(Event event2, double angle): Returns the relative angle from @event1 to @event2.
GetCenter bool GetCenter(Event event2, double x, double y): Returns the point halfway between the events' positions.
GetDistance bool GetDistance(Event event2, double distance): Returns the distance between the event locations.
getAxes bool getAxes(double[] axes): Extracts all axis values from an event.
getAxis bool getAxis(GdkAxisUse axisUse, double value): Extract the axis value for a particular axis use from an event structure.
getDevice Device getDevice(): Returns the device of an event.
getDeviceTool DeviceTool getDeviceTool(): Returns a GdkDeviceTool representing the tool that caused the event.
getDisplay Display getDisplay(): Retrieves the display associated to the @event.
getEventSequence GdkEventSequence* getEventSequence(): Retuns the event sequence to which the event belongs.
getEventStruct GdkEvent* getEventStruct(bool transferOwnership): Get the main Gtk struct
getEventType GdkEventType getEventType(): Retrieves the type of the event.
getHistory GdkTimeCoord[] getHistory(): Retrieves the history of the device that @event is for, as a list of time and coordinates.
getModifierState GdkModifierType getModifierState(): Returns the modifier state field of an event.
getPointerEmulated bool getPointerEmulated(): Returns whether this event is an 'emulated' pointer event.
getPosition bool getPosition(double x, double y): Extract the event surface relative x/y coordinates from an event.
getSeat Seat getSeat(): Returns the seat that originated the event.
getStruct void* getStruct(): the main Gtk struct as a void*
getSurface Surface getSurface(): Extracts the surface associated with an event.
getTime uint getTime(): Returns the timestamp of @event.
ref_ Event ref_(): Increase the ref count of @event.
triggersContextMenu bool triggersContextMenu(): Returns whether a GdkEvent should trigger a context menu, according to platform conventions.
unref void unref(): Decrease the ref count of @event.
