wx.grid.GridCellBoolRenderer

I'm trying to use a GridCellBoolRenderer. According to wxPIA, this
renderer should show a checkbox in the middle of the cell that is
checked for a True value and un-checked for False.

I get a checkbox at the left side of the cell and the only way I can get
it checked is by putting a value of 1 (integer) in the cell. I can
change the alignment by using a GridCellAttr, but is there a way to get
the renderer to respect bool values?

Also, is using a GridCellAttr the only way to set the alignment of an
entire column (other than doing a SetCellAlignment on each cell)? It
seems like there should be a SetColumnAlignment method.

I'm running wxPython 2.8.7.1 with Python 2.5.1 on Ubuntu Gutsy (7.10).

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);
     }

Also, is using a GridCellAttr the only way to set the alignment of an
entire column (other than doing a SetCellAlignment on each cell)? It
seems like there should be a SetColumnAlignment method.

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