AdvToolbar\Office2010 demos

I'm having trouble understanding the Office2010 demos using the AdvToolbar. First, the File AdvShapeButton. How does it bring up the AdvVerticalPolyList? Then, how do the WedgeItems bring up the corresponding AdvVerticalPolyLists? 

OK got it. The ShapeButton is linked to the frame and the frame has its own separate unit.
