Change cursor on mouse hover

Is there a way to change the cursor from the default hand to e.g. cross when the mouse is over an anchor point?
When the mouse is not over anything, I want the cursor to be the standard arrow.
when the mouse is over a shape node, I want it to be a hand.
When the mouse is over one of my anchor points, I want it to be a cross.

You will have to create a custom Behavior class and override its SetMouseCursor method. The sample code here shows how to detect whether the mouse is over an anchor point:

I hope that helps,

Yes, that works fine thanks. The only problem I have now is that the user can click and move the mouse and a new shape is drawn. I do not want this to happen. Previously, moving the mouse like this created a shaded "selection" area. I guess it's the fact I am now using behavior.custom rather behavior.drawLinks for View.Behavior. Any ideas? Thanks.

OK, stand easy. I found a way to do this by overriding StartDraw in my custom behavior, and returning  "new InteractionState(Diagram.Selection, 8, Action.Create);"

Thanks anyhow  Smiley
