Dear all,
I need to work out the dimensions of a gef editor to center an editpart as
the focus of the diagram. I can get the width and height of the platform
shell using (i think thats what it is as it only seems to change when I
resize the top level window and not the editor windows):
getEditorSite().getShell().getSize()
How do I get the size of an editor? While we are here, how do I get the
dimensions of an view? I am hoping that it is more or less the same
process/calls.
Finally, I need the editor to respond to a resize event by repositioning
the elements. What listener/events should I use? as long as I can
recalculate and reposition the model elements, the event fired their will
redraw the editparts so that side is ok.
Thanks in advance!
Raj

I am trying to do this now. Looks like what you need is to make your own
Layout Manager that centers its contents. That is the path I am taking.
But while I think the layout manager is a key, also I need a new figure it
would seem because when the layout manager centers the figure, it causes
the parent figure to appearently resize itself, and we get a loop. So I
gotta figure out a new Pane or Layered figure or something.
Any help is appreciated.
