Are MoveHandles restricted to using MoveHandleLocators? [message #213520]

I need to put a move handle in the middle (both veritical and horizontal)
of a figure (its a line, so a move handle on the right edge will colide
with the resize handle for horizontal lines).

The MoveHandleLocator always positions the handle on 3/4 vertical on the
right edge of a figure. So I tried to use the RelativeHandleLocator but
when I do the cursor is changed to a pointer instead of SIZEALL in the UI
despite it being assigned correctly if I take a look at the MoveHandle in
debug. The pointer does not allow me to move the object with the keyboard.

Any idea what is wrong? Why I am restricted to using the
MoveHandleLocator?

Have you tried setting the locator on the Handle you are using to the
MidpointLocator? Looks like one of the constructor of the MoveHandle takes
a Locator in the second parameter.

MidpointLocator's are for connections only. But your suggestion is
similar to what I tried with the RelativeHandleLocator. I'm using the
MoveHandle(GraphicalEditPart owner, Locator loc) constructor.

In fact I even tried subclassing the MoveHandleLocator and overriding the
relocate() method. Same troubles I get the mouse pointer instead of the
move cursor???

to clarify...

MoveHandle moveHandle = new MoveHandle (getHost (), new
MoveHandleLocator(getHostFigure ());

and
MoveHandle moveHandle = new MoveHandle (getHost(), new
RelativeHandleLocator(getHostFigure (), PositionConstants.CENTER));

both give me a handle but in case 2 its just a pointer and in case 1 its
in the wrong place. How can the locator affect this shouldn't it only
affect position?
