[wxPython-users] wx.grid.Grid doesn't refresh row count

[Werner F. Bruhin]

Hi Aliaksei,

Have you seen this in the wiki:

http://wiki.wxpython.org/index.cgi/UpdatingGridData

i.e. you need to tell the grid that things have changed.

Then why MyGrid's number of rows doesn't change, even though I call MyGrid.ForceRefresh() and MyTable.GetNumberRows() returns correct new number of rows? MyGrid displays new values OK, but then I scroll beyond the new limits and get a whole bunch of IndexErrors...
