GesturePan

gtk.GesturePan is a gtk.Gesture implementation able to recognize pan gestures, those are drags that are locked to happen along one axis. The axis that a gtk.GesturePan handles is defined at construct time, and can be changed through Gesture.panSetOrientation.

When the gesture starts to be recognized, gtk.GesturePan 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 pan signal will be emitted as input events are received, containing the offset in the given axis.

Constructors

this
this(GtkGesturePan* gtkGesturePan, bool ownedRef)

Sets our main struct and passes it to the parent class.

this
this(Widget widget, GtkOrientation orientation)

Returns a newly created gtk.Gesture that recognizes pan gestures.

Members

Functions

addOnPan
gulong addOnPan(void delegate(GtkPanDirection, double, GesturePan) dlg, ConnectFlags connectFlags)

This signal is emitted once a panning gesture along the expected axis is detected.

getGesturePanStruct
GtkGesturePan* getGesturePanStruct(bool transferOwnership)

Get the main Gtk struct

getOrientation
GtkOrientation getOrientation()

Returns the orientation of the pan gestures that this gesture expects.

getStruct
void* getStruct()

the main Gtk struct as a void*

setOrientation
void setOrientation(GtkOrientation orientation)

Sets the orientation to be expected on pan gestures.

Inherited Members

From GestureDrag

gtkGestureDrag
GtkGestureDrag* gtkGestureDrag;

the main Gtk struct

getGestureDragStruct
GtkGestureDrag* getGestureDragStruct(bool transferOwnership)

Get the main Gtk struct

getStruct
void* getStruct()

getType
GType getType()
getOffset
bool getOffset(double x, double y)

If the gesture is active, this function returns TRUE and fills in x and y with the coordinates of the current point, as an offset to the starting drag point.

getStartPoint
bool getStartPoint(double x, double y)

If the gesture is active, this function returns TRUE and fills in x and y with the drag start coordinates, in window-relative coordinates.

addOnDragBegin
gulong addOnDragBegin(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags)

This signal is emitted whenever dragging starts.

addOnDragEnd
gulong addOnDragEnd(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags)

This signal is emitted whenever the dragging is finished.

addOnDragUpdate
gulong addOnDragUpdate(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags)

This signal is emitted whenever the dragging point moves.
