  11. Henri:
  12.  
  13. I have forced redraw in one my view with the following code, picked from
  14. somewhere in either ODF or ODF Example code:
  15.  
  16. void CMyView::UpdateHighlight(Environment* ev, ODShape* selectionShape,
  17. FW_Boolean redraw)
  18. {
  19.         this->Invalidate(ev, selectionShape);
  20.         if (redraw)
  21.         {
  22.                 FW_CFrameFacetIterator iter(ev, this->GetFrame(ev));
  23.                 for (ODFacet* facet = iter.First(ev);
  24. iter.IsNotComplete(ev); facet = iter.Next(ev))
  25.                         facet->GetWindow(ev)->Update(ev);
  26.         }
  27. }
  28.  
  29. Should I be better replacing the facet->GetWindow(ev)->Update(ev) with a
  30. call to this->Draw(ev, facet, selectionShape)?
  31.  
  32. I was not calling Draw directly because I thought doing so will keep a
  33. pending update event for that window. Is that true?
