Difference between ScalableFreeformRootEditPart and ScalableRootEditPart? [message #230793] Sat, 17 February 2007 12:56 Go to next message

Hi!

What is the difference between a ScalableFreeformRootEditPart
and a ScalableRootEditPart?

Is it the only thing, that I may move items to negative coordinates
with a ScalableFreeformRootEditPart?

My problem is, that I have got an editor with a
ScalableFreeformRootEditPart. Now I'm building a save-image-action,
that needs access to the RootEditParts Zoomanager and
the RootEditParts Layers.

ScalableFreeformRootEditPart doesn't provide public-access to these
properties. ScalableRootEditPart does.

Also I would like to have a negative-coordinates-support, I think I have
to switch to ScalableRootEditPart to realize my save-image-action.
Or is there maybe another solution to access Zoomanager and Layers with
a ScalableFreeformRootEditPart?

Greetings, Hermann

Its been a while but IIRC, the freeform does not have 'size' and it takes
its size from its children sort of. The non-freeform one has size and
does not get resized based on children. So if you are not careful where
you put the children they wont be visible.

I believe that is how it was.

Thanks! That sounds good.
So I don't need the FreeformEditPart.
