How can I define which cells are selectable in a graph?

Question

How can I set a specific cell in a graph to be selectable and some others not ?

Accepted Answer

Overriding mxGraph.isCellSelectable is the general idea. For a specific suggestion, you could add a selectable style to all cells as follows:

mxGraph.prototype.isCellSelectable = function(cell)
{
  var state = this.view.getState(cell);
  var style = (state != null) ? state.style : this.getCellStyle(cell);

  return this.isCellsSelectable() && !this.isCellLocked(cell) && style['selectable'] != 0;
 };

And then use the selectable style as follows:

var v1 = graph.insertVertex(parent, null, 'Hello,', 20, 20, 80, 30, 'selectable=0');
