Hi,

in my Project, I generate diagrams and display them to the user in an
GMF generated Editor for further manipulation.
The default layout in GMF positions all nodes perfectly. But in my case
I often have connections with identical source and target. These are
overlapping with other nodes and connections.. the following images show
what I mean:
*Result after generating and programmatically calling the
allignAll-Function: http://imgbox.de/users/public/images/a55317k4.png
*Desired Result: http://imgbox.de/users/public/images/j55097h4.png

My question: Is it possible to layout the connections in a way, that
they don't collide anymore?

Best wishes,
Malte

After reading some Tutorial I tried to change the connection router to
FanRouter in the Root Edit Part:

protected void configureGraphicalViewer() {
super.configureGraphicalViewer();

//....
GraphicalViewer viewer = this.getGraphicalViewer();
RootEditPart root = viewer.getRootEditPart();

if (root instanceof LayerManager) {
((ConnectionLayer) ((LayerManager)
root).getLayer(LayerConstants.CONNECTION_LAYER))
.setConnectionRouter(new FanRouter());
}

}

But I can see no changes in the displayed diagram. Any ideas? The
Connection Routers are said to take care of colliding connections.

Best wishes,
Malte
