GestureDrag
open class GestureDrag : GestureSingle, GestureDragProtocol
GtkGestureDrag
is a GtkGesture
implementation that recognizes drag
operations. The drag operation itself can be tracked throught the
GtkGestureDrag::drag-begin
, GtkGestureDrag::drag-update
and
GtkGestureDrag::drag-end
signals, or the relevant coordinates be
extracted through gtk_gesture_drag_get_offset()
and
gtk_gesture_drag_get_start_point()
.
The GestureDrag
type acts as a reference-counted owner of an underlying GtkGestureDrag
instance.
It provides the methods that can operate on this data type through GestureDragProtocol
conformance.
Use GestureDrag
as a strong reference or owner of a GtkGestureDrag
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
GestureDrag
instance.Declaration
Swift
@inlinable public init(_ op: UnsafeMutablePointer<GtkGestureDrag>)
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 theGestureDrag
instance.Declaration
Swift
@inlinable public init(_ op: UnsafePointer<GtkGestureDrag>)
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 theGestureDrag
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 theGestureDrag
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 theGestureDrag
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GtkGestureDrag>?)
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 theGestureDrag
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GtkGestureDrag>?)
Parameters
op
pointer to the underlying object
-
Designated initialiser from the underlying
C
data type. Will retainGtkGestureDrag
. i.e., ownership is transferred to theGestureDrag
instance.Declaration
Swift
@inlinable public init(retaining op: UnsafeMutablePointer<GtkGestureDrag>)
Parameters
op
pointer to the underlying object
-
Reference intialiser for a related type that implements
GestureDragProtocol
Will retainGtkGestureDrag
