StickyNoteFigure (Comment Box) in the logic example [message #187767]

All,

I am in need of writing a Comment Box in my editor for storing textual
information about the editor. I saw the Logic diagram uses something
similar to what I need. My question is do we need to split up the figure
information from the actual model object? Because in this case, the model
object is fairly simply and is just storing text so why do we need a
BentCornerFigure which extends figure and then StickyNoteFigure which
extends BentCornerFigure? Can't we combine the functionality within the
model object? I understand the need for the feedback figure so we can
provide visual feedback when the object is being moved around.

Any thoughts?

Thank you,
Harsh

Combine what functionality in the model? I'm not sure what you're getting
at.

This still doesn't make sense.

The model object has (static/non-visual) attributes/data.

The edit part provides (dynamic/visual) GUI functionality.

The model object may be shared with other applications so cannot possibly
have GUI functionality.

If by GUI functionality you mean graphical attributes then that is data
but annotation data, that should not polute the model. You will find that
the EDiagram example handles this by leaving an Ecore model unpoluted and
adding an extra graphical model.

Your original question suggested merging ...Figures. The examples are
examples. You can of course refactor to taste.
