GestureDrag

#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().

Constructors

this this(GtkGestureDrag* gtkGestureDrag, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(Widget widget): Returns a newly created #GtkGesture that recognizes drags.

Functions

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.
getGestureDragStruct GtkGestureDrag* getGestureDragStruct(): Get the main Gtk struct
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.
getStruct void* getStruct(): the main Gtk struct as a void*
internalRemoveOnDragBegin void internalRemoveOnDragBegin(OnDragBeginDelegateWrapper source): Undocumented in source. Be warned that the author may not have intended to support it.
internalRemoveOnDragEnd void internalRemoveOnDragEnd(OnDragEndDelegateWrapper source): Undocumented in source. Be warned that the author may not have intended to support it.
internalRemoveOnDragUpdate void internalRemoveOnDragUpdate(OnDragUpdateDelegateWrapper source): Undocumented in source. Be warned that the author may not have intended to support it.
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.

getType GType getType()
getButton uint getButton(): Returns the button number @gesture listens for, or 0 if @gesture reacts to any button press.
getCurrentButton uint getCurrentButton(): Returns the button number currently interacting with @gesture, or 0 if there is none.
getCurrentSequence GdkEventSequence* getCurrentSequence(): Returns the event sequence currently interacting with @gesture. This is only meaningful if gtk_gesture_is_active() returns %TRUE.
getExclusive bool getExclusive(): Gets whether a gesture is exclusive. For more information, see gtk_gesture_single_set_exclusive().
getTouchOnly bool getTouchOnly(): Returns %TRUE if the gesture is only triggered by touch events.
setButton void setButton(uint button): Sets the button number @gesture listens to. If non-0, every button press from a different button number will be ignored. Touch events implicitly match with button 1.
setExclusive void setExclusive(bool exclusive): Sets whether @gesture is exclusive. An exclusive gesture will only handle pointer and "pointer emulated" touch events, so at any given time, there is only one sequence able to interact with those.
setTouchOnly void setTouchOnly(bool touchOnly): If @touch_only is %TRUE, @gesture will only handle events of type #GDK_TOUCH_BEGIN, #GDK_TOUCH_UPDATE or #GDK_TOUCH_END. If %FALSE, mouse events will be handled too.
