Re: [gef-dev] FanRouter and ShortestPathConnectionRouter together

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

Quoting Randy Hudson <hudsonr@xxxxxxxxxx>:

I think that the shapes example uses both routers together.  It should
work fine.  The exception looks like you have a Connection with 0 points.
This should not be possible since SPCR always sets at least the start and
end points.

[gef-dev] FanRouter and ShortestPathConnectionRouter together






Hello,

is there a way to use FanRouter and ShortestPathConnectionRouter together?
Because after using the routing of ShortestPathConnectionRouter I still
have
connections between the same nodes which are overlapping.

If I use the to routers together

ConnectionLayer cLayer = (ConnectionLayer) getLayer(CONNECTION_LAYER);
FanRouter fanRouter = new FanRouter();
ShortestPathConnectionRouter router = new
ShortestPathConnectionRouter(getFigure());
fanRouter.setNextRouter(router);
cLayer.setConnectionRouter(fanRouter);

I'll get the following stacktrace:
