GesturePan
open class GesturePan : GestureDrag, GesturePanProtocol
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 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 theGesturePan
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 underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theGesturePan
instance.Declaration
Swift
@inlinable override public init!(gpointer op: gpointer?)
Parameters
op
gpointer to the underlying object
-
Optional initialiser from a non-mutating
gconstpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theGesturePan
instance.Declaration
Swift
@inlinable override public init!(gconstpointer op: gconstpointer?)
Parameters
op
pointer to the underlying object
-
Optional 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 theGesturePan
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GtkGesturePan>?)
Parameters
op
pointer to the underlying object
-
Optional initialiser from the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theGesturePan
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GtkGesturePan>?)
Parameters
op
pointer to the underlying object
-
Designated initialiser from the underlying
C
data type. Will retainGtkGesturePan
. i.e., ownership is transferred to theGesturePan
instance.Declaration
Swift
@inlinable public init(retaining op: UnsafeMutablePointer<GtkGesturePan>)
Parameters
