Hello all,
I have attached a simple program to demonstrate an issue I am seeing with the sorting of model data in a table view. The code is below and should compile/run. I am using QT Creator 1.2.1 on Win Vista 32 Business.
THe error I am seeing is: for example:
if the data in row 4 column 0 is changed from 7000->3300, the order of the displayed data changes in the table view, however it only seems to sort based on the first character in the sequence... Can someone please explain how one would go about sorting by the entire integer in column 0 on data changed?

Thanks,
