Recall the graphical syntax of UML class diagrams. Classes are
represented as boxes and all kinds of relations are represented as arcs
(with arrows) between them. Then the attributes and operations of the
classes follow a concrete textual syntax. For example:
+doFoo(String):Int
And everybody knows that the method's name is 'doFoo', being public,
having a parameter of type 'String' and a return value of type 'Int'. In
statemachines it is similar, e.g., with the conditions for the
transitions. So in those cases you have a graphical syntax and another
textual syntax combined internally. I'm wondering if it is possible with
Xtext to realise such functionality. I thought that I stumbled one day
in the web about a blog entry describing something like that, but I
couldn't find it anymore. Maybe one of you guys can help me where to
find it?
best regards,
Gilbert

Hi Alex,
I don't think that this part of the documentation is what I'm searching
for. This documentation aims at "To illustrate how to build a GMF on top
of an XtextResource". That wasn't my initial question. I don't want a
GMF editor which is synchronized with a textual editor from Xtext. I
want a GMF editor in which I can edit, e.g., labels in a defined textual
syntax (like attributes from UML class diagrams) which is integrated in
the diagram. The reason is to save canvas space. If I could model some
concepts of a model in a textual manner within the canvas of the GMF
diagram it would be very cool. The fine difference between your
suggestion and my requirement is that I don't need two different
representations (textual and graphical) of the same model but the
textual notation integrated into the graphical notation.
best regards,
Gilbert

Please look at the GMF-Xtext-Example that ships with Xtext. You can find
it at Eclipse->New->Examples->Xtext Examples.
Besides putting a GMF-Editor on top of an Xtext Resource, the example
embeds an Xtext editor into GMF; For example, to edit properties. To my
understanding this is exactly what you are asking for.
There is also a presentation about it:
http://www.slideshare.net/meysholdt/converging-textual-and-g raphical-editors
As Alex said, the integration has originally been done by Jan Koehnlein.
cheers,
Moritz

Hi Moritz,
thanks for the hint. I thought that in this example a GMF editor is only
put on top of an Xtext Resource and not this nice editor for editing
properties. This is what I'm searching. But is there a possibility to
present the properties in the GMF editor with a defined syntax after
editing them with the popup Xtext editor? Maybe that's a GMF question
and not an XText question.
best regards,
Gilbert
