禁用JGraphX上实际顶点的连接

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);
