Widget.computeTransform

bool computeTransform(gtk.widget.Widget target, out graphene.matrix.Matrix outTransform)

Computes a matrix suitable to describe a transformation from widget's coordinate system into target's coordinate system.

The transform can not be computed in certain cases, for example when widget and target do not share a common ancestor. In that case out_transform gets set to the identity matrix.

To learn more about widget coordinate systems, see the coordinate system overview.

Parameters

`target`	the target widget that the matrix will transform to
`outTransform`	location to store the final transformation

Returns

true if the transform could be computed, false otherwise
