Declaration [src]

gtk_gesture_get_bounding_box (
  GtkGesture* gesture,
  GdkRectangle* rect

Description [src]

If there are touch sequences being currently handled by gesture, this function returns TRUE and fills in rect with the bounding box containing all active touches. Otherwise, FALSE will be returned.

Note: This function will yield unexpected results on touchpad gestures. Since there is no correlation between physical and pixel distances, these will look as if constrained in an infinitely small area, rect width and height will thus be 0 regardless of the number of touchpoints.

Available since: 3.14



Type: GdkRectangle

Bounding box containing all active touches.

The argument will be set by the function.
The returned data is owned by the instance.

Return value

Type: gboolean
