How to access CXTPTabPaintManager?

Hello,

Does anyone know how to access CXTPTabPaintManager within an SDI application?

Also, is there only one instance of CXTPTabPaintManager per application, or each CXTPDockingPaneTabbedContainer has its own?

Here is what I I tried in absence of a better idea (I know, it's a really stupid thing to do but I was desperate):
 - walking through all panes
 - checking if their containers are CXTPDockingPaneTabbedContainer(s)
 - for each CXTPDockingPaneTabbedContainer found, access its CXTPTabPaintManager through GetPaintManager()

This is how the code looks like:

  CXTPDockingPaneInfoList& lst = _paneManager.GetPaneList(); // CXTPDockingPaneManager _paneManager;
  POSITION pos = lst.GetHeadPosition();
  while (pos)
  {
    CXTPDockingPane* pane = (CXTPDockingPane*) lst.GetNext(pos);
    CXTPDockingPaneBase* container = pane->GetContainer();
    if (!container || container->GetType() != xtpPaneTypeTabbedContainer)
      continue;
    CXTPDockingPaneTabbedContainer* tabs = static_cast<CXTPDockingPaneTabbedContainer*>(container );
    CXTPTabPaintManager* tabPaintManager = tabs->GetPaintManager();
    tabPaintManager->GetColorSet()->m_clrHeaderFace.clrDar k = RGB(255,0,0);
    tabPaintManager->GetColorSet()->m_clrHeaderFace.clrLig ht = RGB(0,0,255);
  }

Unfortunately, CXTPDockingPaneTabbedContainer::GetPaintManager() is a protected method so the above code fails to compile.

I'm sure there is a simple way to do the same thing.

Thanks in advance for any help!
