I have created my own create tool by subclassing ConnectionCreationTool.
The Java DOC for the handleCreateConnection method indicates that the method
can be overriden to allow for 'prompting the user...' for connection
information. I have had a difficult time getting this to work.
I create a popup-menu with the options, but then the code would execute
before the menu item would be selected. I have added a readAndDispatch loop
to prevent this, but it only works on the MAC and Linux and not on Windows.
If I don't have the loop but just one call, it works on the MAC and Windows,
but not Linux.
I also tried to create a pop-up dialog to get around this, but the loosing
focus and other problems made this situation worse (the targetEditPart is
erased for example).
Is their a suggested way to 'prompt the user'? Are they any samples?
I am using GEF 3.3.2v20080129 under Eclipse 3.3.2 M20080221-1800
Thanks.

I might have found my problem. It seems that by performing the read and
dispatch, I distribute the mouse up event too soon. I over-rode the
handleViewerExited to not process if in the middle of my menu selection.
This appears to fix the problem, but I want to know if this is an acceptable
method.
Thanks.
