Hi,

I would like to use delete action with a multiPageEditorPart.
so
I have create EditorContextMenuProvider in which i have write:


action = getActionRegistry().getAction(ActionFactory.DELETE.getId());
if (action.isEnabled())
menu.appendToGroup(GEFActionConstants.GROUP_EDIT, action);

But the "action.isEnabled" return always false whereas in a simple editor
it runs.
What have to do?

Thanks

You have to update the selection actions of your sub editor.
There?s already a thread in this newsgroup.

Here you go:

<cite>

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

getSite().getWorkbenchWindow().getSelectionService().addSele ctionListener(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());
}
}
