How to get the correct zoomManger when using a MultiPageEditorPart [message #197089]

I have added a ZoomComboContributionItem to the ActionBarContributor for the
MultiPageEditorPart. The ZoomComboContributionItem uses a partListener to
call setZoomManager based on the partActivated call. Unfortuneatly
partActivated does not get called when page activation chnages in the
MultiPageEditorPart. So i get the last active zoomManager .

I dropped a selectListener off the ZoomComboContributionItem and this seems
to work , but seem a bit heavy for this purpose. Any other lighter ideas?

IWorkbenchPage wp = getPage();
final ZoomComboContributionItem zitem = new ZoomComboContributionItem(wp);
toolBarManager.add(zitem);
wp.addSelectionListener( new ISelectionListener()
{
// a selection listsner seems a bit heavy
// for this purpose, but it is one way to
// get the correct zoomManager after the active page
// chnages in the MultiPageEditorPart
public void selectionChanged(IWorkbenchPart part, ISelection selection)
{
zitem.setZoomManager((ZoomManager) part.getAdapter(ZoomManager.class));
}

});

Create your own MultiPageZoomManager, and call setPage(ZoomManager delegate)
when you switch pages. Then fire zoom level property changed event and the
combo should update.

Your ActionBarContributor should be a
MultiPageEditorActionBarContribitor. Then you will get notified whenever
the active page changes (setActivePage() will be called). As far as I
know, this is the simplest solution.

This works perfectly for the ZoomComboContributionItem , but then the other
things that the GEF ActionBarContributor provides like addGlobalActionKey &
addRetargetAction no longer work since there is a bunch of action plumbing
that ActionBarContributor adds.

I worked around by using the orignl impl of ActionBarContributor and setting
setting a reference to the ZoomComboContributionItem in

public void setActiveEditor(IEditorPart part) {
super.setActiveEditor(part);
if (part instanceof NotationMultiPageEditor)
{
NotationMultiPageEditor p = (NotationMultiPageEditor) part;
p.setZoomComboContributionItem(zitem);
}
}
// Then in the MPE.

protected void pageChange(int newPageIndex)
{
super.pageChange(newPageIndex);
if(myItemHack != null)
{
myItemHack.setZoomManager((ZoomManager)
this.getActiveEditor().getAdapter(ZoomManager.class));
}

}
