Enabling and displaying the grid is straightforward too.

Hi,
Thanks for the reply. I have implemented the getAdapter() method in my
EditPart ala Logic example.
However after debugging I have confirmed that the code never gets called in
my application.
Is there something I have to turn on to enable this or something ?
Thanks again,
Alan.

Not sure what else to do here...how can I access the updated javadoc for

This occured when I changed my top level figure from being a FreefromLayer
to being a ScrollPane.
Does this make sense to you as to why this would happen ?

So, you have set both the visibility and the enablement properties on the
viewer, right? In the case below, if you can't see it, can you still snap
to it? That is, when moving figures around in your editor do you see them
snapping? Maybe your grid was showing, but you couldn't actually see it
because there was some opaque figure in the way. Was your freeform layer
opaque? You should investigate why returning a scrollpane works, whereas
the freeform layer doesn't. You shouldn't have to return the scrollpane.
Were you setting the freeform layer's layout to a FreeformLayout? Is your
editor using a ScalableFreeformRootEditPart?

Not quite sure what snapping looks like but no they don't seem to be
snapping. They seem to be moving as before I ever tried the SnapToGrid.

Yes my freeform layer was opaque all along and yes I've just seen that the
freeform layer's layout was set to FreeformLayout
A big part of my problem here is that I'm getting my info on this subject
piecemeal.
Is there a how-to guide, article or any kind of documentation somewhere that
I can use to help me ?

There you have it. Your FreeformLayer shouldn't be opaque. The GridLayer
is underneath the primary layers, so if your layer is opaque, any layers
underneath wouldn't be visible.
