I have EditParts A and B. I have connectors A1 and B1. EditParts A can
only be connected together with A1 connectors. EditParts B can only be
connected together with B1 connectors.
How do I accomplished this rule?
It seems that in A's EditPolicy.getConnectionCreateCommand, I should
somehow be able to determine the type of connector in the
CreateConnectionRequest. I've tried request.getNewObjectType(), which
always returns 1. I've tried request.getNewObject(), which returns null.
Any ideas?
Thanks.
protected Command getConnectionCreateCommand(CreateConnectionRequest
request) {
Shape source = (Shape) getHost().getModel();
int style = ((Integer) request.getNewObjectType()).intValue();
ShapeConnectionCreateCommand cmd = new
ShapeConnectionCreateCommand(source, style);
request.setStartCommand(cmd);
return cmd;
}

Those methods should work. It depends on the CreationFactory you configured
the tool with.

That was it, in the tool's CreationFactory. Thanks again! It's really cool
when GEF starts to come together and make sense.
