Dragging multiple figures vs. one [message #502555]

I have use the Shape Diagram Editor as an example to create my own GEF editor. However, when I drag around multiple figures in my own editor, they all get dragged to the same mouse location, ignoring the different offset of each shape.

Dragging multiple parts in the GEF Shapes example works fine. My question is: where does the GEF framework catch the multi-selection when selecting and dragging multiple figures? In this scenario, which objects get created for each figure, and which once for the drag as a whole?

Thanks for any insights!

Regards,
Gerrit

In this case, org.eclipse.gef.tools.DragEditPartsTracker#getCommand() sends
a ChangeBoundsRequest to each selected EditPart. In my cae they are handled
individually in
org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy#cre ateChangeConstraintCommand().
