EventTouchRef

public struct EventTouchRef : EventTouchProtocol

The EventTouchRef type acts as a lightweight Swift reference to an underlying GdkEventTouch instance. It exposes methods that can operate on this data type through EventTouchProtocol conformance. Use EventTouchRef only as an unowned reference to an existing GdkEventTouch instance.

Used for touch events. type field will be one of GDK_TOUCH_BEGIN, GDK_TOUCH_UPDATE, GDK_TOUCH_END or GDK_TOUCH_CANCEL.

Touch events are grouped into sequences by means of the sequence field, which can also be obtained with gdk_event_get_event_sequence(). Each sequence begins with a GDK_TOUCH_BEGIN event, followed by any number of GDK_TOUCH_UPDATE events, and ends with a GDK_TOUCH_END (or GDK_TOUCH_CANCEL) event. With multitouch devices, there may be several active sequences at the same time.

  • ptr
    Untyped pointer to the underlying `GdkEventTouch` instance.
    

    For type-safe access, use the generated, typed pointer _ptr property instead.
