===============


.. class:: XLSBackground(object)

   This is a class which holds information about the cell background, in terms
   of background colour and background pattern (hatching).

   .. method:: __init__(self, book, xf_index)

      Default class constructor.
      
      :param `book`: an instance of the `xlrd.Book` class;
      :param `xf_index`: an index into `xlrd.Book.xf_list`, which holds a
       reference to the `xlrd.sheet.Cell` class (the actual cell for `xlrd`).


   .. method:: CombineAttr(self, attr)

      Combines the input attribute `attr` with the features of the :class:`XLSBackground` class.
      
      :param `attr`: an instance of :class:`grid.GridCellAttr`.


   .. method:: CreateBackgroundColour(self, background_colour, pattern_colour, fill_pattern)

      Creates a suitable wxPython colour for the cell background starting from
      a `xlrd` tuple representing this colour.
      
      :param `background_colour`: a tuple representing the RGB components of the
       cell background colour. If `background_colour` is ``None``, use the
       default ``wx.SYS_COLOUR_WINDOW``;
      :param `pattern_colour`: a tuple representing the RGB components of the
       cell pattern colour;
      :param `fill_pattern`: the pattern to use to draw hatches on top of the
       background.


   .. method:: Draw(self, dc, rect)

      Actually draws the cell background and pattern hatching on a grid cell.
      
      :param `dc`: an instance of :class:`wx.DC`;
      :param `rect`: an instance of :class:`wx.Rect`, representing the cell rectangle.
