GestureSingle

GtkGestureSingle is a GtkGestures subclass optimized for singe-touch and mouse gestures.

Under interaction, these gestures stick to the first interacting sequence, which is accessible through [method@Gtk.GestureSingle.get_current_sequence] while the gesture is being interacted with.

By default gestures react to both %GDK_BUTTON_PRIMARY and touch events. [method@Gtk.GestureSingle.set_touch_only] can be used to change the touch behavior. Callers may also specify a different mouse button number to interact with through [method@Gtk.GestureSingle.set_button], or react to any mouse button by setting it to 0. While the gesture is active, the button being currently pressed can be known through [method@Gtk.GestureSingle.get_current_button].

Functions

getButton uint getButton(): Returns the button number @gesture listens for.
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.
getExclusive bool getExclusive(): Gets whether a gesture is exclusive.
getGestureSingleStruct GtkGestureSingle* getGestureSingleStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
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.
setExclusive void setExclusive(bool exclusive): Sets whether @gesture is exclusive.

getLastUpdatedSequence GdkEventSequence* getLastUpdatedSequence(): Returns the GdkEventSequence that was last updated on @gesture.
getPoint bool getPoint(GdkEventSequence* sequence, double x, double y): If @sequence is currently being interpreted by @gesture, returns %TRUE and fills in @x and @y with the last coordinates stored for that event sequence.
