Method
GtkGestureget_bounding_box
Declaration [src]
gboolean
gtk_gesture_get_bounding_box (
GtkGesture* gesture,
GdkRectangle* rect
)
Description [src]
If there are touch sequences being currently handled by gesture,
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.
Parameters
rect-
Type:
GdkRectangleBounding box containing all active touches.
The argument will be set by the function. The returned data is owned by the instance.
