GesturePanRef
public struct GesturePanRef : GesturePanProtocol, GWeakCapturing
GtkGesturePan
is a GtkGesture
for pan gestures.
These are drags that are locked to happen along one axis. The axis
that a GtkGesturePan
handles is defined at construct time, and
can be changed through [methodGtk.GesturePan.set_orientation
].
When the gesture starts to be recognized, GtkGesturePan
will
attempt to determine as early as possible whether the sequence
is moving in the expected direction, and denying the sequence if
this does not happen.
Once a panning gesture along the expected axis is recognized,
the [signalGtk.GesturePan::pan
] signal will be emitted as input
events are received, containing the offset in the given axis.
The GesturePanRef
type acts as a lightweight Swift reference to an underlying GtkGesturePan
instance.
It exposes methods that can operate on this data type through GesturePanProtocol
conformance.
Use GesturePanRef
only as an unowned
reference to an existing GtkGesturePan
instance.
