   .. method:: Clone(self)

      Creates a new copy of this object.                  

      :rtype: :ref:`wx.grid.GridCellAttr`








   .. method:: DecRef(self)

      This class is reference counted: it is created with ref count of 1, so calling :meth:`DecRef`   once will delete it.                  

      Calling :meth:`IncRef`   allows to lock it until the matching :meth:`DecRef`   is called.                   





   .. method:: GetAlignment(self)

      Get the alignment to use for the cell with the given attribute.                  

      If this attribute doesn't specify any alignment, the default attribute alignment is used (which can be changed using :meth:`wx.grid.Grid.SetDefaultCellAlignment`   but is left and top by default). 

      Notice that `hAlign`  and `vAlign`  values are always overwritten by this function, use :meth:`GetNonDefaultAlignment`   if this is not desirable. 







      :rtype: `tuple`



                  



      :returns: 

         ( `hAlign`, `vAlign` ) 








   .. method:: GetBackgroundColour(self)

      Returns the background colour.                  

      :rtype: :ref:`Colour`








   .. method:: GetEditor(self, grid, row, col)

      Returns the cell editor.                  


      :param `grid`: 
      :type `grid`: wx.grid.Grid
      :param `row`: 
      :type `row`: int
      :param `col`: 
      :type `col`: int




      :rtype: :ref:`wx.grid.GridCellEditor`








   .. method:: GetFont(self)

      Returns the font.                  

      :rtype: :ref:`Font`








   .. method:: GetKind(self)



      :rtype: :ref:`wx.grid.GridCellAttr.AttrKind`








   .. method:: GetNonDefaultAlignment(self)

      Get the alignment defined by this attribute.                  

      Unlike :meth:`GetAlignment`   this function only modifies `hAlign`  and `vAlign`  if this attribute does define a non-default alignment. This means that they must be initialized before calling this function and that their values will be preserved unchanged if they are different from ``wx.ALIGN_INVALID``. 

      For example, the following fragment can be used to use the cell alignment if one is defined but right-align its contents by default (instead of left-aligning it by default) while still using the default vertical alignment: ::

          hAlign = wx.ALIGN_RIGHT
          vAlign = wx.ALIGN_INVALID

          hAlign, vAlign = attr.GetNonDefaultAlignment()



                

      :rtype: `tuple`







      :returns: 

         ( `hAlign`, `vAlign` ) 







      .. versionadded:: 2.9.1 
     








   .. method:: GetOverflow(self)



      :rtype: `bool`








   .. method:: GetRenderer(self, grid, row, col)

      Returns the cell renderer.                  


      :param `grid`: 
      :type `grid`: wx.grid.Grid
      :param `row`: 
      :type `row`: int
      :param `col`: 
      :type `col`: int




      :rtype: :ref:`wx.grid.GridCellRenderer`








   .. method:: GetSize(self)



      :rtype: `tuple`







      :returns: 

         ( `num_rows`, `num_cols` ) 








   .. method:: GetTextColour(self)

      Returns the text colour.                  

      :rtype: :ref:`Colour`








   .. method:: HasAlignment(self)

      Returns ``True`` if this attribute has a valid alignment set.                  

      :rtype: `bool`

      Returns ``True`` if this attribute has a valid background colour set.

      Returns ``True`` if this attribute has a valid text colour set.

      This class is reference counted: it is created with ref count of 1, so calling :meth:`DecRef`   once will delete it.

      Sets the alignment.                  

      `hAlign`  can be one of  ``ALIGN_LEFT`` ,   ``ALIGN_CENTRE``   or   ``ALIGN_RIGHT``   and  `vAlign`  can be one of  ``ALIGN_TOP`` ,   ``ALIGN_CENTRE``   or   ``ALIGN_BOTTOM`` .
