Whenever the distance between both tracked sequences changes, the gtk.gesture_zoom.GestureZoom.scaleChanged signal is emitted to report the scale factor.

Methods

GType _gType() @property nothrow

GestureZoom self() nothrowReturns `this`, for use in `with` statements.

GestureZoomGidBuilder builder() static nothrowGet builder for [gtk.gesture_zoom.GestureZoom] Returns: New builder object

double getScaleDelta() nothrowGets the scale delta.
