Hi,
Is it possible to remove Note attachment Connection Assistant Handle from
the Figure? And How I can only have incoming or Outgoing assistant Handle?
If the figure already have one connection it should not show the handle.
Regards,
Sandip

Sandip,
You would need to install your own ConnectionHandleEditPolicy in your
editparts to override the one that gets installed there by default (that
is the
org.eclipse.gmf.runtime.diagram.ui.editpolicies.ConnectionHa ndleEditPolicy
installed in the GMF runtime code).
To learn about EditPolicies take a look at the section titled "Editing
and EditPolicies".
