the Point the user clicked.
I can't get access to the mouse location. The only place I see that you can
get it would be in org.eclipse.get.tools.SelectionTool, but the
getLocation() method is protected. My plan is to get the mouse location in
ContextMenuProvider and give to my Action. Alternatively, if the EditPart
knew where it was clicked, that would also work.
Maybe I am looking in the wrong place? This was somewhat discussed in a
recent post 'How to get the EditPart at the mouse location'.
Thanks

While I agree that the FAQ points out a valid issue, I don't think this
means you should not provide access to the mouse location because the mouse
will be over the editor nearly all the time. Instead, it could be up to the
developer to provide a default location as you described if the mouse is not
over the editor.
Here is one workaround I came up with: I have extended the
org.eclipse.gef.tools.SelectionTool in order to make one protected method
public; this gives me access to the mouse location . Then I set the default
tool on the DefaultEditDomain of my GraphicalEditor to my own SelectionTool,
and also load it. Here is the code from the constructor of my editor:
DefaultEditDomain editDomain = new DefaultEditDomain( this );
editDomain.setDefaultTool( new SelectionTool() );
editDomain.loadDefaultTool();
setEditDomain( editDomain );
Another possibility is to change the default mouse tool to one that places
your node at the location of the next mouse-click. You can do this in the
run()-method of your action like this:
CreationTool tool = new CreationTool( new DefaultCreationFactory(
.... ) );
UMLEditor editor = (UMLEditor) getWorkbenchPart();
editor.getEditDomain().setActiveTool( tool );
where DefaultCreationFactory implements CreationFactory. Naturally the rest
of your plugin needs to support this also by creating (in a subclass of
AbstractTransferDropTargetListener) and processing the CreateRequest.

The popup menu gets shown when a MenuEvent is generated. If you look at that
event you will see that there is NO x,y data. GEF is NOT hiding the mouse
location from you.
If you want to cheat, you can call Display.getCurrent().getCursorLocation().
