Support for complex edge labels [message #1775664]

Hello,

I was wondering if there is a way to position a complex node (i.e. a node containing other nodes) adjacent to an edge, essentially positioning it as a label?

I saw there was some documentation about this here for KLay: rtsys.informatik.uni-kiel.de/confluence/display/KIELER/Dynamic+Label+Sizing

I was wondering if there are any updates for ELK?

Thank you for your guidance on this,

Jake

Hi Jacob,

we have no built-in ability to treat nodes as we treat labels as that would blur the distinction between the two and make a lot of things in the algorithm much more complicated.

What you might want to do is call automatic layout several times: once with a graph that describes only your complex node, and a second time with a graph that describes the diagrams that complex node should be placed in. In that second graph, you could model that node as a label of the same size the node would have. When applying the layout results, you would apply the coordinates assigned to the label to the compound node.

Cheers,
Chris

I wanted to let you know, I implemented the two-pass approach that you suggested, and it is working well.
