[Qt-interest] [Performance] Inserting thousands of rows

[Scott Aron Bloom]

Don't use TableWIdget, use TableView and a custom model..

 

Make sure your model doesn't block on loading the data...

Subject: [Qt-interest] [Performance] Inserting thousands of rows

 

Hello,

I've a question about performance (or visual performance) of an
application

Let's take a common QTableWidget. Let's say I'd like to insert ....
10.000 rows. Now, usually my whole application (in most languages) will
block, until the rows are inserted. So it does in QT at the moment,
using a standard QT Designer form with a TreeView and a TableWidget.

Do you have any ideas to (in example) have an own thread handling the
QTableWidget, so the rest of the application won't block, so I can still
use the Menu / TreeView while the Table is loading?

Kind regards,
Georg
