* was added in 2.8.
* @GDK_DAMAGE: the content of the window has been changed. This event type
* was added in 2.14.
* @GDK_TOUCH_BEGIN: A new touch event sequence has just started. This event
* type was added in 3.4.

* was added in 3.4.

* was added in 3.4.

* was added in 3.4.
* @GDK_TOUCHPAD_SWIPE: A touchpad swipe gesture event, the current state
* is determined by its phase field. This event type was added in 3.18.
* @GDK_TOUCHPAD_PINCH: A touchpad pinch gesture event, the current state
* is determined by its phase field. This event type was added in 3.18.
* @GDK_PAD_BUTTON_PRESS: A tablet pad button press event. This event type
* was added in 3.22.
* @GDK_PAD_BUTTON_RELEASE: A tablet pad button release event. This event type

* added in 3.22.
* @GDK_EVENT_LAST: marks the end of the GdkEventType enumeration. Added in 2.18
*
* Specifies the type of the event.
*
* Do not confuse these events with the signals that GTK+ widgets emit.
* Although many of these events result in corresponding signals being emitted,
* the events are often transformed or filtered along the way.
*
* In some language bindings, the values %GDK_2BUTTON_PRESS and
* %GDK_3BUTTON_PRESS would translate into something syntactically
* invalid (eg `Gdk.EventType.2ButtonPress`, where a
* symbol is not allowed to start with a number). In that case, the
* aliases %GDK_DOUBLE_BUTTON_PRESS and %GDK_TRIPLE_BUTTON_PRESS can
* be used instead.
