Drop Listener for Connection [message #194655]

Hello All,

I have a simple model containing Components and Connections.
When I drag a connection from Component1(source editpart) and drop it on
Component2(target editpart) I have to open a dialog to take values for
that particular connection.So i have to basically open a diolog on drop of
the connection.

I tried the following :

1>In my xxxDiagramEditor initializeGraphicalViewer() i added the following
getDiagramGraphicalViewer().addDropTargetListener(new
MyDropTargetListener())

2>In my xxxConnectorEditPart i installed DragDropEditPolicy
installEditPolicy(EditPolicyRoles.DRAG_DROP_ROLE, new
DiagramDragDropEditPolicy)

When I debug and check i found out that its not getting inside
MyDropTargetListener().

Am I missing some link..or is there any other better way of solving the
problem.

Thanks in advance.

Regards,
Shwetha

Hello Shwetha,

Try modifying generated ConnectionCreateCommand - this command should be
called to create actual connection instance in the end of the process, so
you can patch it to open dialog.

Thanks Alex :)

It helped me getting the diolog but on click of OK of the diolog the
entered value is not getting refreshed in the GMF Editor.

Thanks in Advance.

Hello Shwetha,

Try debugging corresponding EditPart to see the reason why domain model notification
was skipped (by the label?).
