Hi!
You use FreeformGraphicalRootEditPart in Logic Example. Documentations don't
really show a difference to GraphicalRootEditPart. Will the
GraphicalRootEditPart be dropped in the future? What about the overviews?
Will there be a Freeform with a overview?
Cu, Gunnar

Freeform is the preferred way, and yes, GraphicalRootEditPart will be
dropped. The difference is that Freeform allows you to extend the diagram
surface in all 4 direction (as opposed to just right and down for the other
root). And, it extends the diagram due to "nodes" being moved, or as a
result of benpoints on connections. GraphicalRoot does not grow when you
bend connections.

This is a very valuable explanation. I tried running the old GEF 1.0 that
used not to have Freeform* interfaces & classes. In the logical diagram
editor, it is indeed true that if one drags & drops an object (for example,
an XOR gate) to above the top of the editor windows or after the left corner
of the editor windows, then the dropped object is no longuer accessible! If
you drag& drop behond bottom or right limits, then the object is not lost,
but you don't have automatic scrolling to keep track of you gesture. Nice
bug fix indeed, but I don't quite undersand why it involved creating a new
set of classes / interfaces... it was a bug isn't it?
May I suggest the following addition to GEF FAQ:
Q: FreeformGraphicalRootEditPart is used in Logic Example (build 20020821).
Documentations don't really show a difference to GraphicalRootEditPart. Will
the GraphicalRootEditPart be dropped in the future?
A: Freeform is the preferred way, and yes, GraphicalRootEditPart will be
dropped. The difference is that Freeform allows you to extend the diagram
surface in all 4 direction (as opposed to just right and down for the other
root). And, it extends the diagram due to "nodes" being moved, or as a
result of benpoints on connections. GraphicalRoot does not grow when you
bend connections.
Best regards,
Alex.
