Is it possible to create a connection without using the palette ?
I want to connect two "ports" (OutPortEditPart with InPortEditPart) by
clicking on the "out-port" and dragging the connection to the "in-port"
(or vice versa).
All worked fine as long as I used a flyout-palette with the
ConnectionTool ... but now I removed the palette, and simply want to
start connecting by clicking on the corresponding EditPart.
Can someone please provide a snippet on how to achive this behaviour? I
simply don't get it :-(
thanks in advance
Florian

hmm,
It works for me. What exactly are you doing?
I used
DefaultEditDomain defaultEditDomain = new DefaultEditDomain(this);
defaultEditDomain.setActiveTool(new ConnectionCreationTool());
in the editor constructor.
Anyhow, I just realized that the connection tool is active *all* the time,
so other stuff like selecting EditParts and moving / resizing them will
not be possible straight off without further work. Is this what you want?
Best,
Brian.

strange... I actually did exactly the same...
I partially solved the problem now by adding a MouseListener on the
source-ports' figure.
In the "mousePressed" handler I make something like
" getViewer().getEditDomain.setActiveTool(CONNECTION_CREATING_ TOOL) ".
But I'm not sure if this is the right spot... I now get some strange
update problems with the connection visuals :
If the tool was set as active once, only the last added connection is
painted correctly if moving the source-ports' edit part around
(source-ports may have more than one outgoing connection).
refreshSourceConnections() / refreshTargetConnections() doesn't work.
What actually *does* work is moving around the target-port or open/close
the whole editor. In these cases all connections are updated correctly -
just until I activate the tool again for the first time....
hmmm...
thanks
Florian

This isn't the right way. You should return the Connection
CreationDragTracker as the tracker when the mouse is over the appropriate
locations. Also, those locations should probably show the connection cursor
on mouse over or some hint on hover.
