[news.eclipse.modeling.gmf] Re: How to set the center of a newly created

["D. Rolfes" <rolfes.daniel@xxxxxx>]

Hi,

I've searched the newsgroup for solutions and there were suggestions to 
set a breakpoint to SetBoundsCommand. I did the following in the 
LayoutPolicy in the "protected Command getCreateCommand(CreateRequest 
request)" method:

req.setLocation(//a fixed position));

This works fine.

My problem is that the location depends on the size of the Figures I 
want to create. So I figured I have to somehow get to the corresponding 
EditPart or Figure to get the size. The SetBoundsCommand is afaiu 
invoked while the Mouse is moved (mouse_move). At this point the 
EditPart and the Figure are not even created. I think they will be 
created during the "Mouse Click" (mouse_up).
My problem is quite similiar to this one:
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/msg11496.html

So as i understand, what I need is a place where the mouse location is 
known and I am able to get to the created EditPart or Figure.
After that I can use setLocation() on the created Figure, or is this the 
wrong idea?

Could someone please point me in the right direction?

Thanks,
Daniel
