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

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 ------------------------------------------------------------------------------ _______________________________________________ Gtk2hs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/gtk2hs-devel
