Re: wxpython grid GRIDTABLE_NOTIF Y_ROWS_DELETED

Change the message call in RemoveData() to

self.GetView(). ProcessTableMes sage(wx.grid.Gr idTableMessage(
self,wx.grid.GR IDTABLE_NOTIFY_ ROWS_DELETED, len(data), 1))

The ..._ROW_DELETED message requires two args, the index of the first
row and the number of rows to be removed. Similarly for colums.

PS) Also, check the DoUpdate() method in this example
