Hello,
I am designing an graphical editor for Voice XML Applications using GMF.
Suppose during application startup, i want to have an wizard using which i
can create certain default elements, i am successfully able to create the
notational ascept of the element. That element appears on the editor as
soon as i start my new project.
But i want to update simultaneously the semantic ascept of the element too.
For example:
Suppose i want to have a structure like the following in my sematic file
during startup:
<Vxml..>
<Menu...>
</Vxml>
where menu represents the a dialog tag in VXML Applications. I am able to
display the menu diagrmatically on the editor but not able to update the
xml file as shown above.
Investigation: From my knowledge, when we create a new diagramfile, there
are two resources( a diagram resource and a model resource) The model
resource has the "Vxml" to be set as its document root using the
"resource.getContents.add("Object") method. Now suppose i want to add a
"MenuType" under this VXML Type how should i go about doing this.
The two resources use the " resource.save(Map options) " method to save
the initial contents into the file. Can anyone please help me, on how can
i create this default elment during startup and update my xml file.
Thanx,
Ganesh

I'm assuming you're overriding:
....diagram.part.XXXDiagramEditorUtil.createNewDiagramFile()
Here's an example from the MindmapDiagramEditorUtil; it
creates a new topic element at creation time.
=== Original code ====================================
if (diagram != null) {
diagramResource.getContents().add(diagram);
diagram.setName(diagramFile.getName());
diagram.setElement(model);
}
try {
java.util.Map options = new HashMap();
options.put(XMIResource.OPTION_ENCODING, "UTF-8"); //$NON-NLS-1$
modelResource.save(options);
diagramResource.save(Collections.EMPTY_MAP);
} catch (IOException e) {
MindmapDiagramEditorPlugin.getInstance().logError("Unable to store
model and diagram resources", e); //$NON-NLS-1$
}
=======================================================
=== Modified code to create a root topic on creation ==
if (diagram != null) {
diagramResource.getContents().add(diagram);
diagram.setName(diagramFile.getName());
diagram.setElement(model);
}
//==== Add Topic (semantic model)==
Topic newTopic = MindmapFactory.eINSTANCE.createTopic();
newTopic.setName("SomeNewTopic");
model.getRootTopics().add(newTopic);
//=== Add Topic (notation view)
ViewService.createNode(diagram, newTopic, kindParam,
MindmapDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
try {
java.util.Map options = new HashMap();
options.put(XMIResource.OPTION_ENCODING, "UTF-8"); //$NON-NLS-1$
modelResource.save(options);
diagramResource.save(Collections.EMPTY_MAP);
} catch (IOException e) {
MindmapDiagramEditorPlugin.getInstance().logError("Unable to store
model and diagram resources", e); //$NON-NLS-1$
}
=======================================================
That's it!
(I hope I understood your question correctly :-))
