HI all,
i want to integrate graphical editor with my customize view part as like
as outline view part show when we drag and drag a figure from palette to
graphical editor it reflects in outline view.
I study the diagram plug in code which generated by gmfgen model
but i am not able to understand how graphical editor will reflects the
change in outline view.
If anyone have any idea about that please guide me.
Thanks in advance

OK, first you need the emft ecore diagram modeler. If you are using
eclipse 3.3 you can't install it with the update site, because it need
emf 2.4. The outline itself will work in 3.3. So you grep the archive
and unpack it, just like other plug ins.
You only needed to build two classes (xxxDiagramOutlinePage and
xxxModelNavigator), and changed one method in xxxDiagramEditor,
getAdapter(Class type) where you need to create and return the
xxxDiagramOutlinePage. I have attached these files as an example.
After this the outline will be present. In 3.3 and GMF 2.01 you will
also need to add D&D by hand, as I did this for my current plug in I
just peek in the EMFT code, load it in your workspace via cvs.
The heavy part is to get the multi diagramming feature to work. I did
not really understand what's going on, I just did what I found. You will
need to check the emft sources and reproduce the solution for your plug
in, just like I did.
Perhaps we are lucky and Jacques Lescot will explain us what he did, and
why.
In https://bugs.eclipse.org/bugs/show_bug.cgi?id=206778 is an other
integration solution I did not tried out. You could patch the gmf
source, provided by Enrico Schnepel.
I hope this will help.
You could vote for this bug. :)
greetings, urs.

You can do something like this in xxxNavigator :
protected void createEMFMenu(IMenuManager manager, EObject
selectedObject) {
if (!isEMFMenuEnabledFor(selectedObject)) {
return;
}
TransactionalEditingDomain editingDomain =
TransactionUtil.getEditingDomain(getDiagramResource());
IStructuredSelection structuredSelection= new
StructuredSelection(selectedObject);
DeleteAction deleteAction = new DeleteAction(editingDomain);
deleteAction.updateSelection(structuredSelection);
manager.add(new ActionContributionItem(deleteAction));
....
greetings urs.

Thanks for your support,Now my outline view is complete but
i am not able to add the support of drag and drop in outline tree
viewer.The normal dnd functioning doesn't work with outline tree viewer.
Please give me idea about how to implement drag and drop in outline tree
viewer.
Thanks in advance.

I think GMF 2.1 will support this by generation.
To get this to working 2.01 I looked in the emft sources and did the
following :
in xxxDiagramEditor

Creates a dndeditpolicy(attachment example) and install it in in your
diagram editpart :

it will also reflect on Diagram editor means the source widget becomes

Currently the normal tree drag and drop not works for me, I think you
provided me the code for drag and drop in editor, it works in graphics
editor but never reflects in outline viewer.What i want is if i drag a
widget over another widget then in tree viewer the tree item corresponding
widget becomes child of target widget tree item.
Please guide me.
Thanks in advance.

but using this code only tree item's position is change, but the drag over
operation is not working means when i drag a tree item over another tree
item the source tree item will be child of target tree item but it doesn't
work in outline tree viewer(as in normal tree viewer it works ),
Can you provide me some guidance that how it will work in outline tree
viewer.

My code snippet was only about dragging from the outline in the diagram
editor.
I'm afraid I do not know this, and I have no own use case for the moment
to investigate it. So I would suggest you look in your generated emf
Editor plugin, I think this is an EMF question, perhaps you ask in the
EMF newsgroup, the man who knows will answer. (Ed)
