Hi,

I need to urgently do some processing before the user adds a node to the canvas.

I assume the only way to do this is to override the method(s) that gets invoked when the (create node) tool in the palette becomes active, i.e., the user clicks on this tool.
Can anyone tell me which method of which class would I have to override to do my processing?

An alternative would be to override the method that gets called when the user already activated the tool and is performing a click on the canvas to add the node.

Thanks,
Thomas L
