  easy to fix, only used by Windows specific code.

  missing method
  
  ? implement ourself ?

  
- QListView::adjustColumn
  missing method
  
  ? implement ourself ?


- QListView::setSortOrder
  QListView:: setSortColumn
  missing method
  
  could be replaced by setSorting.


- QListViewItemIterator
  missing (filtering) constructor
  
  could be replaced by implementing the filter ourself.  
    
    
- -framework Quicktime
  required to link on MacOSX
  
  easy to fix.
  

- QAction

  could be fixed by setting the parameters with the set methods.
