Why are my adapters being removed when I'm using diagram partitioning? ...and how to listen to the c [message #236238]

Hi,

I'm still new on GMF :-)

I'm working with galileo...

I have a GMF editor and I'm using diagram partitioning(one model for
both editors).
After a double-click opens a new editor but all my adapters I added
before to the elements in der first editor are being removed (I get a
notification "REMOVING_ADAPTERS") ... but why are they being removed? I
need them to be adapted because I have a view which listens to them...

when I accepted that they obviously have to be removed I decided to
listen to the change of the active editor. So I can add my adapter again
when certain editor (the first one) is active again... but how can
listen to this change?

I need this because my next step is to avoid a dirty editor so I want to
save the content of an editor if another is getting active.

Thanks in advance for some hints to solve my problems.

René

Hi René,

concerning your change problem an implementation of IPartListener could
be what you are searching for. Write a class which implements this
interface. Something like this.

public class MyPartListener implements IPartListener
{
@Override
public void partActivated(IWorkbenchPart part)
{
System.out.println("do something");
}

@Override
public void partBroughtToTop(IWorkbenchPart part)
{
System.out.println("do something");
}

@Override
public void partClosed(IWorkbenchPart part)
{
System.out.println("do something");
}

@Override
public void partDeactivated(IWorkbenchPart part)
{
System.out.println("do something");
}

@Override
public void partOpened(IWorkbenchPart part)
{
System.out.println("do something");
}
}

Than just add this implementation to the page which holds your editor.
This could be done in your editor's init method.

public void init(IEditorSite site, IEditorInput input) throws
PartInitException
{
...
IPartListener partListener = new MyPartListener();
site.getPage().addPartListener(partListener);
...
}

Now you can react on the event when you switch between the tabs of you
opened editors. Hope that helps.

Cheers,

Martin

Thanks for the replies,

but this bug doesn't really cover my problem(or question) because I
don't have any problem with graphical elements...my added adapters are
being removed during opening my second editor

Hello René,

I think adapters were removed because of resetting editor input (model elements
were reloaded from file again.. Where do you attach adapters to model elements?

Hi Alex,

I'm not sure if it is the best way to solve but I add the adapter in
handleEventNotification() of my ***CanonicalEditPolicy because this is
one possibility to notice when a new element was added... or is there a
better way?

Thanks in advance.

Hello René,

I doubt this method will be called on starting the editor for each diagram
element..
I think you have to initially traverse the model attaching corresponding
adapters in one of ???DocumentProvider + handle appropriate notifications.
