Re: [udig-devel] How can I get the modal tools switching events?Look for

[Jody Garnett <jody.garnett@xxxxxxxxx>]

I am not sure if there is such an event; we don't tend to add things until people request them. When you implement your own tool you are given various methods to know when you have been activated (incase you need to prepare the map with some graphic commands for feedback etc...).

Still MapViewer (used by the MapEditor to display the map; also used by your own code) has a setModalTool method let us see where that goes.

public void setModalTool( ModalTool tool ) {

        if (activeTool != null) {

            // ask the current tool to stop listening etc...

            activeTool.setActive(false);

            activeTool = null;

        }

        if( tool == null ){

            return;

        }

        activeTool = tool;

        activeTool.setContext(getToolContext());

        activeTool.setActive(true);

    }

So I don't see any event notification there ...
