Here is the challenge:
1. Create a Palette with Group, Text, Label, and Table widgets.
2. Build a display of sets of these widgets from a serialized
representation
of a screen layout, including the text values for the Labels and Table
Column headings, rows and columns.
3. Be able to manipulate the size and screen position of the widgets (by
dragging), change the text content of the Labels.
4. Be able to add new Labels and Texts, to include the text content of the
Labels.
5. Be able to delete Labels and Texts.
6. The size of a containing Group would either be dynamic based on the
movement of the child widgets, or by dragging the boundary.
If this is doable using the existing GEF version, any hints on where to
start
would be appreciated.

When you say Table widget, if you are referring to the SWT Table, this might
be difficult. I'm not sure if "screen scraping" works for those widgets
when they are offscreen.

You did not address the question of text manipulation. I get the
impression that GEF does not deal with a real widget, in the case of a
Label or Text, it would just be a Rectangle, and not be able to contain
any text. This would mean that there would have to be 2 separate steps to
performing an edit, one graphical one, and another to manage the text, is
this the case?

You can edit text in the same way that you can edit text in a Tree. Via
CellEditor. GEF lets you overlay a CellEditor on top of a figure in your
diagram.
