gtk:gesture-bounding-box (gesture)

gesture -- a gtk:gesture object

The gdk:rectangle instance for the bounding box containing all active touches.

If there are touch sequences being currently handled by gesture, this function returns the bounding box containing all active touches. Otherwise, false will be returned. 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, the width and height of the rectangle will thus be 0 regardless of the number of touch points.
