I created a small custom GUI builder in my RCP application to let user
to build own composite. By move composite with mouse I have followed
example Snippet46 (Composite example snippet: intercept mouse events
(drag a button with the mouse)). I used FormLayout. I would like to see
a cross when moving composite to see where will be the composite placed
and to see also a tooltip with grid line (please see attached picture).
Blue dash line shows a location where will be composite paste (at the
same time into grid). The same way work also other builders (e.g. SWT
Designer). On the background is Canvas and moving is Composite.

My question is how to implement tooltip and dash line cross?

Thanks for any advice or examples!

Martin
