EventTouchProtocol
public protocol EventTouchProtocol
The EventTouchProtocol
protocol exposes the methods and properties of an underlying GdkEventTouch
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see EventTouch
.
Alternatively, use EventTouchRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
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.
