Hello everybody,

Is it possible to have a splitter in the GEF editor. Right now, i am
planning to use GEF editor only as a view and not as an editor.

On left side of the splitter, i want to draw one EMF model and on the
right side of the splitter, i want to draw another EMF model.

Is this possible?
If so, how?.
Any samples or links would help me.

Thank you very much
Best Regards
Shruthi

By deriving the EditorPart and creating two graphical viewers just like
composites contained in a sash, you might archive this...

I am really interested to see how this would work because there can only
be one root edit part per graphical viewer and from what I know, a one to
one mapping between a viewer and a palette.

Thats why I said I think you should start down from EditPart and build
up your TWO graphicalviewers.

You can trick with using the same composite to display palette by
notifying the composite that holds the palette by whick graphical viewer
is active or has the control (up to you can be mouse over event or focus
event).

On the other hand you may also think of using the multitabeditor. Thats
usually how it is done when there needs to be two+ way of displaying the
edit domain. Ref: Visual form editors. Code and visual display of your
forms contents. Comparing to that example you will need to implement the
second graphical viewer in the second tab as opposed the texteditor.

Hope makes more sense now.

if you go with multitabeditor it is easy. You will develop virtually to
editors on each tab using the same model domain.

Or if you go with the two graphical viewers on the same page,
have a look at the GraphicalEditor class. It will give you a staring
point. You should throw a sash form and put two graphical viewers.

If you have SWTDesigner you will understand what I meean. If you do not have
they have trial download for a month. Download and install. Editor has
two tabs and first tab is GEF. It has Actions and Controls viewers
stacked on top of each other. Although it is closed source it will give
you the idea...

Hope it makes more sense now...

That sounds like an SWT question. GEF can be used anywhere you can create a
Canvas, so just create a SashForm, and put a GraphicalViewer on either side
of it.
