GestureSwipe

#GtkGestureSwipe is a #GtkGesture implementation able to recognize swipes, after a press/move/.../move/release sequence happens, the #GtkGestureSwipe::swipe signal will be emitted, providing the velocity and directionality of the sequence at the time it was lifted.

If the velocity is desired in intermediate points, gtk.gesture_swipe.GestureSwipe.getVelocity can be called on eg. a #GtkGesture::update handler.

All velocities are reported in pixels/sec units.

class GestureSwipe : GestureSingle {

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

static GType _getGType();

GType _gType [@property getter];

GestureSwipe self();

static GestureSwipeGidBuilder builder();

this(gtk.widget.Widget widget);

bool getVelocity(double velocityX, double velocityY);

gulong connectSwipe(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 swipes.

Functions

connectSwipe gulong connectSwipe(T callback, Flag!"After" after): Connect to Swipe signal.
getVelocity bool getVelocity(double velocityX, double velocityY): If the gesture is recognized, this function returns true and fill in velocity_x and velocity_y with the recorded velocity, as per the last event(s) processed.
self GestureSwipe self(): Returns this, for use in with statements.

_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.
