Hi,
I've tried your suggestion and it does indeed seem to show an increase in performance. I've measured it as being around 10% of improvement for a large dataset (10000 records on the listview). My datasets will probabibly be around 1000 records, and at that level the difference doesn't seem very noticeable. It takes around 4 seconds on my machine to sort the list, and even though it may sound a little bit too demanding from me but I think I will probably have a much better result by implementing it directly on C++. I was betting on Python for the simplicity, but I believe I really hit a soft spot this time.
Do you know how Python delivers its functions to the C++ interface? I mean in this case, would it be justifiable to believe most of the performance hit comes from the fact that the C++ QListView sorting routine has to call a function that is being run on the Python virtual machine a number O(n * log n ) times? Would this incur in a boundry cross? If this is the case, I am pretty confident that the solution should be heading for C++ in this one.
Thanks for all your help Troy. Fernando
