It's boolean in the sense of zero and non-zero, not necessarily Python 
True and False singletons. It also depends on the data type used in the 
table for that cell.  For example if the default string table is used 
then the bool renderer will actually be comparing values to "" and "1". 
  Here is the code:

     bool value;
     if ( grid.GetTable()->CanGetValueAs(row, col, wxGRID_VALUE_BOOL) )
     {
         value = grid.GetTable()->GetValueAsBool(row, col);
     }
     else
     {
         wxString cellval( grid.GetTable()->GetValue(row, col) );
         value = wxGridCellBoolEditor::IsTrueValue(cellval);
     }

If there was such a method all it would do is set the column attribute 
with a GridCellAttr.
