Reloading/Refreshing GMF editor without reopening the editor [message #174083]

Hi,

My requirement is to reload the GMF Editor whenever there is a change in
the tree.For example:

If I add a element in the tree then I have to refresh the editor with the
new object.

I tried to reopen the editor by calling the EditorUtil's openDiagram() but
it will create another diagram file.I want to use the same diagram file
and then update the values.

Note : The tree uses different model and GMF editor uses different model.
I have a mapper to load data from tree to GMF editor.

Any help would be appreciated.

Thanks in advance.

Regards,
Shwetha

Shwetha,

The generated EMF editor listens to workspace deltas and refreshes the
contents of any resource that's changed. I though the GMF editor did
the same thing. What is the nature of these changes you describe? Are
they done by updating the workspace? Or using a command? I would
expect either of those to work properly...

Hi Ed,

I have a Tree model for TreeView and GMF model for GMF editor and a
mapper(pojo) that maps between the 2 model as I explained before.

I'm not using workspace concept or commands to do any modification.

If I have to update the TreeView with any values changed in the GMF editor
I use resourceChanged() in XXXDiagramEditor and it works fine.(as you said
about the default editor feature).

My doubt is how to notify/reload the GMF editor when there is a change in
the TreeView without reopening the editor.

Hope my requirement is clear.Any help is appreciated.

Thanks in advance.

Regards,
Shwetha

Shwetha,

I'm still kind of confused. The editor will be showing the contents of
the resources in the workspace, right? So how does a change to the
TreeView affect what's in the workspace? If it doesn't, then how is the
GMF editor to even know about the TreeView's contents? There's just a
puzzle piece missing for me to understand this...

Hi Ed,

I have used a interface LoadNotifier to update all the views.
In the xxxDiagarmEditor I implement interface LoadNotifier with a method
notifyRefresh(I have to inlcude snippet here to refresh/reload the GMF
editor on any change in the TreeView).

The workspace resource you mean is the semantic gmf model is it???
Since i'm using 2 different model i cant directly update the gmf
model.Hence I'm using Mapper to map from Tree Model to GMF model and
Notify mechanism to refresh both.

Hope this is clear.

Thanks in advance.

Shwetha

Shwetha,

Hopefully the GMF folks understand it because I don't know about these
mechanisms...

Hello Shwetha,

Try using IWorkbenchPage.openEditor(editorInput, xxxDiagramEditor.ID);

To my understansing in this point GMF editor should recognize that new elements
were created and perform update automatically.
If you are just updating model file content and saving it to the eclipse
workspace then GMF editor should note corresponding changed resource and
perform update automatically..

Hi Alex,

Thanks alot for your reply.

But how do I intialise the editorInput with my gmfModel object.
It throws ClassCast Exception.

In this case wont it create another diagram file and semantic file???

Awaiting for your reply.

Thanks and Regards,
Shwetha

Question.
Would it be correct to say that you have 2 mutually exclusive semantic
models? one that you using for the tree and one that you are using in the
gmf editor?

Hello Shwetha,

It should not. You can use FileEditorInput or URIEditorInput instance. Just
create corresponding instances and use it.

Its not mutually exclusive.I just fill the TreeModel data in GMF Model.

Hope this will make the requirement clear.
