Folks,
I am trying to create a diagram with a grid like layout and trying to use
the SnapTo Grid to do this.
It is working fine for moving an object but I can't figure out how to use
the SnapTo functionality on object creation.
In the following method for example I just get ChangeBoundsRequest
public int snapRectangle(Request request, int snapLocations,
PrecisionRectangle rect, PrecisionRectangle result)
Any help would be appreciated.
Thanks.

Ok maybe I was being a bit quick off the mark when I said the SnapToGrid was
working fine for moving objects.
I'm not quite sure how I go about setting the co-ordinates that the objects
can snap to.
Firstly I'm assuming the method snapRectangle() is what I have to override ?
Secondly I'm looking at that method and I'm not sure how to go about setting
the co-ordinates.
Do I have to set the gridx and gridy values ?
Sorry that this question is a bit vague but if you could point me towards an
example even it would be great.
Background
========
I need a grid like the one attached.
As you can see the cells are not uniform in size
As the diagram zooms the space between the cells changes.
Therefore my grid co-ordinates change constantly.
So I need my SnapToGrid to mirror the GridLayer which I used to draw what
you see
As I say any thoughts would be great
Thanks.
