This document: http://www.x.org/docs/Xext/shape.pdf has this to say about it ... only one event type can be selected via the extension, XShapeSelectInput provides a general mechanism similar to the standard Xlib binding for window events. A mask value has been defined, ShapeNotifyMask that is the only valid bit in mask that may be specified. So I think you will need to use both.
