I managed to get it going for the line edit- but am stuck with
checking a cell in a table as cells do not have the set validator
attribute- here's the code i had for the line edit:

 self.ui.Thickness_datum.setValidator(QtGui.QDoubleValidator(-999.0,
999.0, 2, self.ui.Thickness_datum))

for the table i thought it would be:

self.ui.table_process.item(row,2).setValidator(QtGui.QDoubleValidator
(-999.0, 999.0, 2, self.ui.table_process.item(row,2)))

Any help would be appreciated
