disable connection of actual vertex on JGraphX

Question

I need to disable connection of actual vertex if edges of vertex >= 2

if(graph.getModel().getEdgeCount(cell)>=2){ graphComp.setConnectable(false); // but for actual cell, not for all vertexes }

How can I do that?

Answer 1

Instead of mxGraphComponent.setConnectable(false) you can disable the connection for one Cell by calling mxCell.setConnectable(false).

If you want it to be enabled again when the edgecount goes down again you can use:

int maxEdgeCount = 2;

cell.setConnectable(cell.getEdgeCount < maxEdgeCount);
