In this case, 0 is stored in out_point.
Widget.computePoint
bool computePoint(gtk.widget.Widget target, graphene.point.Point point, out graphene.point.Point outPoint)Translates the given point in widget's coordinates to coordinates relative to target’s coordinate system.
In order to perform this operation, both widgets must share a common ancestor.
Parameters
target | the [gtk.widget.Widget] to transform into |
point | a point in widget's coordinate system |
outPoint | Set to the corresponding coordinates in target's coordinate system |
Returns
true if the point could be determined, false on failure.
