I have a SubGraph whose CollapsedObject is set to a GoImage. This SubGraph also has a label. When collapsed, it really looks like a GoGeneralNode.
When PickableBackground is true, and the node is collasped, the graph is selected wherever we click inside its bounding box, even if this is outside of the collapsed object. When PickableBackground is false, only the icon is active for selection.
I could correct the problem by setting PickableBackground to true/false in the Expand/Collapse functions of the subgraph, but I really wonder if this is the desired behaviour, and if I missed something.
