How to optemize QTableWidget?

[mismael85]

Hi,
I have a problem now ,I have a QTableWidget with 6 columns and more than 100628 row. It means (6 * 100628) of QTableWidgetItem. so when i fill the table the following two problems are arising :-
1- the application takes 1 minute approximately to fill the table(which is a long time for me).
2- the application takes a huge memory in the RAM.

so i thought that i should only display a limited number of rows and when the user scroll down, another rows are displayed.
is that possible ? how?
is there any better way to do this?
thank you

Yes, use QTableView with a model.

but i think that QTableView also loads all the items at startup. and also loads all of them in the memory.
or it just loads the displayed items?

That depends on the model.
See the canFetchMore() and fetchMore() functions.
