I created some shapes in the view. Each shape has a number. I want to get the serial number of the shape when I put the mouse on it, but I don't know how to connect the number with the shape.
I tried to save AIS_InteractiveObject pointer when I created the shape, and use Context->SelectionManager()->Selector()->OnePicked()->Selectable() to get the pointer when mouse move. but the pointer not same.
How can I contact the AIS_InteractiveObject and qwidget?
