Hi!
I was looking at the article (which is great!) Display a UML Diagram using
Draw2D http://www.eclipse.org/articles/Article-GEF-Draw2d/GEF-Draw2 d.html,
and I was thinking if there is a way to implement some drag capabilities to
the labels which are child of the connection (the labels with 'contains',
'1..*', etc). I can't change their position...
Is there a way to do that?
Thanks in advance.

Yes, Randy. I knew that. My question is: how to allow a Label, which is a
child of a connection, be moved with the mouse? And show the selection
handles, etc..? When I click on the label, the connection is selected. I
can't select only the label..
Thanks

Desculpe. To be able to select the label, the label should be a child
editpart of the connection editpart. To be able to drag the label, you will
need an editpolicy for dragging, which modifies some property in your model,
which then updates the locator which places the label. How this is done
depends on the locator, but the simplest locator would be a (dx, dy) offset
from the connection's endpoint.
