GI.Gdk.Structs.EventTouch
Contents
Description
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.
