Hi all,
I'd like to ask, whether there exists a (free) implementation of editpart
interface working with SWT controls (real windowed ones, not just TreeItems)
instead of Figures.
Thanks.
Tibor

Randy, thanks for the answer.
The reason why I think about SWT controls as the View part in the MVC
pattern is their ability to edit content (texts) "in-place" - control
traversal with caret for free. I'm working on an editor so this would be for
me a great help - I'd only be responsible for layout and "decoration"
painting.
Editing model through property sheets, outline views or context menus seems
more straightforward for me - that's my impression. I'm a newbie in GEF, so
I am probably wrong....

GEF allows in-place editing of text via CellEditors. You can always
reproduce the illusion of traversal with the TAB key.

It would help if you described the type of editor you are building.
