Hi,
I create a figure from the palette onto the diagram. The mouse location
and the upper-left point of the newly created element will be the same
after the creation.
But I would like the mouse location to be the center of the newly
created element.
How can I achieve this?
Thanks,
Daniel

Hi,
thanks for your answer.
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/m sg11496.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 you please point me in the right direction?
Thanks,
Daniel

as you have request.setLocation(), you also have request.getSize
in your "protected Command getCreateCommand(CreateRequest
request)" method you return a command, just go in that command class.
there also you are setting the location and size of your object in the model.
so you can use any of the method...
i suggest doing it in the command is a better practice..,
