Basically, what I'm trying to do is not allow creation of edges or vertex at all. Nothing should be editable, the user is only meant to be allowed to re-position Vertices, but never modify the actual graph.

Any help?

At the moment I have all these


but it still allows adding Edges.

Try graph.setConnectable(false)

What example is your app based on?

It's based on the HelloWorld example, just to clarity, the only problem I have left right now is the graph editor/display allowing drag and drop from the center of a vertex to another vertex which adds a new edge between two vertices.

still allows adding of edges unfortunately.

may have something to do with mxCellMarker or mxConnectionHandler.

mxConnectionHandler: "Connection handler creates new connections between cells. This control is used to display the connector icon, while the preview is used to draw the line. mxEvent.CONNECT fires between begin- and endUpdate in mouseReleased. The cell property contains the inserted edge, the event and target properties contain the respective arguments that were passed to mouseReleased."

I'll try and find how its it relates to mxGraphComponent and see if I can replace them with overridden methods.

Any further help would be appreciated.

Is this Java? If so, please tag JGraphX, not mxGraph.

This answer worked. Thank you. It seemed that it was my mistake, I set .setConnectableEdges(false) to the graph model.. it had to be set in the graph component itself rather than the graph model. My apologies, this was just slightly confusing as all other interactions allowed/disallowed are declared in the graph model.

Thank you.

Gaudenz, can you change your comment into an answer and edit as appropriate to make it clearer if you so wish so I can sign it off as "the answer" :)

Again, much appreciated for the help
