GesturePan

open class GesturePan : GestureDrag, GesturePanProtocol

GtkGesturePan is a GtkGesture implementation able to recognize pan gestures, those 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 gtk_gesture_pan_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 GtkGesturePan::pan signal will be emitted as input events are received, containing the offset in the given axis.

The GesturePan type acts as a reference-counted owner of an underlying GtkGesturePan instance. It provides the methods that can operate on this data type through GesturePanProtocol conformance. Use GesturePan as a strong reference or owner of a GtkGesturePan instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GesturePan instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkGesturePan>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GesturePan instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkGesturePan>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the GesturePan instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
