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_get_velocity() can be called on eg. a #GtkGesture::update handler.

All velocities are reported in pixels/sec units.

class GestureSwipe : GestureSingle {

protected

GtkGestureSwipe* gtkGestureSwipe;

GtkGestureSwipe* getGestureSwipeStruct(bool transferOwnership);

void* getStruct();

this(GtkGestureSwipe* gtkGestureSwipe, bool ownedRef);

static GType getType();

this(Widget widget);

bool getVelocity(double velocityX, double velocityY);

gulong addOnSwipe(void delegate(double, double, GestureSwipe) dlg, ConnectFlags connectFlags);

}

Constructors

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

Functions

addOnSwipe gulong addOnSwipe(void delegate(double, double, GestureSwipe) dlg, ConnectFlags connectFlags): This signal is emitted when the recognized gesture is finished, velocity and direction are a product of previously recorded events.
getGestureSwipeStruct GtkGestureSwipe* getGestureSwipeStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
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.

From GestureSingle

gtkGestureSingle GtkGestureSingle* gtkGestureSingle;: the main Gtk struct
getGestureSingleStruct GtkGestureSingle* getGestureSingleStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
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.
