Hi,
I'm trying to integrate Graphiti in my own workspace management. So, I
extended the DiagramEditor to override the save management behavior
(doSave & isDirty).
I'm facing the following issues:
- The DiagramEditorInternal instantiate the DiagramEditorBehavior in the
constructor which make it quite hard to change the behavior of the
DiagramEditor.
- DiagramEditorBehavior is internal and not intended to be subclassed by
client
Can we imagine to add a method to create the DiagramEditorBehavior where
I can override it in my editor to provider my custom behavior ??
And Can we have an interface like IDiagramEditorBehavior so that I can
implement it ??
I attached a patch.
code snippet:
/**
* Instantiates a new diagram editor.
*/
public DiagramEditorInternal() {
behavior = createDiagramEditorBehavior();
}
protected IDiagramEditorBehavior createDiagramEditorBehavior() {
return new DiagramEditorBehavior(this);
}
--------------------------------------------------
public interface IDiagramEditorBehavior extends
IEditingDomainProvider, IDisposable {
IUndoContext getUndoContext();
Resource[] doSave(IProgressMonitor progressMonitor);
boolean isDirty();
void init(IEditorSite site, IEditorInput editorInput, Runnable
dirtyStateUpdater);
void setFocus();
}
Thank you in advance,
Ali

Ali,
you' re right: the API of the DiagramEditor is not really as it should be.
There's already a bugzilla tracking this
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=336488).
On the other hand, the DiagramEditorBehavior class contains very specific
stuff, of which some parts are really essential to the Graphiti framework.
This is a class that we would rather not want to open up. If you have
specific use cases just let us know so that we can think of ways how to
enable them.
In your case in order to override doSave and isDirty behavior: you might do
that simply in your subclass of DiagramEditor (simply not delegating to
super). You will of course get the warnings regarding non-API usage, but
that will then be a topics for the above mentioned bugzilla and you may
ignore these warnings for now.

Hi Michael,
Thank you for your answer.
For the save management, I can of course override methods in the editor
without delegating to the editor behavior, but I prefer to keep my code
as close as possible to Graphiti.
In my workspace, I have many models according to some scopes defined by
the user (e.g. ProjectScope), and each model has a global editing
domain.When calling
org.eclipse.graphiti.ui.internal.editor.DiagramEditorBehavio r#handleChangedResources()
all resources in my resource set are unloaded.
Same issue is also attaching a content adapter to the resource set which
leads in my case of performance issues.
(editingDomain.getResourceSet().eAdapters().add(problemIndic ationAdapter);)
It would be perfect when the editor manages only the owned resource (The
Graphiti resource).
You can keep the DiagramEditorBehavior in an internal package and don't
open it, but just change the way it's instantiated for the editor.

Hi Ali,
I think it would be best to track this in the scope of the bugzilla for
opening up the editor API
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=336488), since it very much
affects what we have to make public inside the editor and what not. Could
you add this request as a comment to this bugzilla?
Thanks,
Michael
