Re: [gef-dev] FanRouter and ShortestPathConnectionRouter together

[Christian Dupuis <spring@xxxxxxxxxxxxxxxxxx>]

Hi,

first of all thanks for your answer Randy.

Unfortunatly the shapes example only uses the SPCR standalone. If I try to
extend the logic example in order to use FanRouter with SPCR I don't see any
connections anymore.

I changed the refreshVisualls() in LogicDiagramEditPart to the following

else {
       AutomaticRouter fanrouter = new FanRouter();
       ShortestPathConnectionRouter router =
			new ShortestPathConnectionRouter(getFigure());
       fanrouter.setNextRouter(router);
	cLayer.setConnectionRouter(fanrouter);
	getFigure().setLayoutManager(new    
ShortestPathConnectionRouter.LayoutWrapper(
				layout,router));
	}

Is there a way to extend the SPCR to handle overlapping/same connections like
FanRouter? Any hints would be great.

Greetings
Christian
