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.GestureDrag.getOffset and gtk.gesture_drag.GestureDrag.getStartPoint.

class GestureDrag : GestureSingle {

this(void* ptr, Flag!"Take" take);

static GType _getGType();

GType _gType [@property getter];

GestureDrag self();

static GestureDragGidBuilder builder();

this(gtk.widget.Widget widget);

bool getOffset(double x, double y);

bool getStartPoint(double x, double y);

gulong connectDragBegin(T callback, Flag!"After" after);

gulong connectDragEnd(T callback, Flag!"After" after);

gulong connectDragUpdate(T callback, Flag!"After" after);

}

Constructors

this this(void* ptr, Flag!"Take" take)
this this(gtk.widget.Widget widget): Returns a newly created #GtkGesture that recognizes drags.

Functions

connectDragBegin gulong connectDragBegin(T callback, Flag!"After" after): Connect to DragBegin signal.
connectDragEnd gulong connectDragEnd(T callback, Flag!"After" after): Connect to DragEnd signal.
connectDragUpdate gulong connectDragUpdate(T callback, Flag!"After" after): Connect to DragUpdate signal.
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.
self GestureDrag self(): Returns this, for use in with statements.

From GestureSingle

_getGType GType _getGType()
_gType GType _gType [@property getter]
self GestureSingle self(): Returns this, for use in with statements.
builder GestureSingleGidBuilder builder(): Get builder for gtk.gesture_single.GestureSingle
button uint button [@property getter]: Get button property.
button uint button [@property setter]: Set button property.
exclusive bool exclusive [@property getter]: Get exclusive property.
exclusive bool exclusive [@property setter]: Set exclusive property.
touchOnly bool touchOnly [@property getter]: Get touchOnly property.
touchOnly bool touchOnly [@property setter]: Set touchOnly property.
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 gdk.event_sequence.EventSequence getCurrentSequence(): Returns the event sequence currently interacting with gesture. This is only meaningful if gtk.gesture.Gesture.isActive returns true.
getExclusive bool getExclusive(): Gets whether a gesture is exclusive. For more information, see gtk.gesture_single.GestureSingle.setExclusive.
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.
