Hi Axel,

I'm developing a gtk+ tool like Mac QuickSliver (search and do for you),
like this screenshot:

Like screenshot, first search TreeView just match 7 (less 10), so i want 
decrease
TreeView height to make ScrolledWindow don't display VAdjustment.

This need calculate total height of TreeView :

   treeViewHeight = headerHeight + cellHeight * cellRows
  
Default, TreeView is formed by the HeaderButton and BinWindow (contain
treeViewColumn), but C code in GTK+ make "header_height" private, 
and haven't any way to get height of HeaderButton.

For get "headerHeight", i push new coordinate functions that bring in
Gtk+ 2.12 (simple enough, so i push directly)

------------------------------> new functions start 
<------------------------------
  treeViewConvertBinWindowToTreeCoords,
  treeViewConvertBinWindowToWidgetCoords,
  treeViewConvertTreeToBinWindowCoords,
  treeViewConvertTreeToWidgetCoords,
  treeViewConvertWidgetToBinWindowCoords,
  treeViewConvertWidgetToTreeCoords,
------------------------------> new functions end   
<------------------------------

And make below functions deprecated:

------------------------------> deprecated functions start 
<------------------------------
  treeViewWidgetToTreeCoords,
  treeViewTreeToWidgetCoords,
------------------------------> deprecated functions end   
<------------------------------

Now i can use below functions to get header height of treeView:

-- | Get header height.
treeViewGetHeaderHeight :: TreeViewClass self => self -> IO Int
treeViewGetHeaderHeight treeView = do
  (_, by) <- treeViewConvertTreeToBinWindowCoords treeView (0, 0)
  (_, wy) <- treeViewConvertTreeToWidgetCoords treeView (0, 0)
  return $ wy - by

Cheers,

  -- Andy
