[news.eclipse.tools.gef] Re: how to delete element in a MultiPageEditorP

["Ingo Koch" <ingo.koch[nospam]@sap.com>]

Here you go:

<cite>

What I had to do additionally was
1. to register the MultipageEditor as SelectionListener.

getSite().getWorkbenchWindow().getSelectionService().addSelectionListener(th
is);

2. Implement the ISelectionListener allmost as you suggested:
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
    if (this.equals(getSite().getPage().getActiveEditor())) {
         if (netEditor.equals(getActiveEditor()))
            netEditor.selectionChanged(getActiveEditor(), selection);
        }
    }
}

3. to override the selectionChanged method in my Editor.
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
    super.selectionChanged(part, selection);
    if (this.equals(part)) { // Propagated from MyMultiPageEditor.
        updateActions(getSelectionActions());
    }
 }
