PySide + QTableView example

Asked 16/10, 2013 at 18:34 Answered 7/12, 2018 at 15:21

Can anyone point me to a simple example of QTableView in PySide?

I found the QTableView docs but unfortunately they don't give an example, and I'm very new to PySide, so I don't even know how to start. (I am very familiar with the JTable in Java Swing, so I know how to use table models.)

You might also have a look at the Itemviews examples of PySide although I found them kind of outdated. But some contain examples of QTableViews and QAbstractTableModels – Opheliaophelie 30/1, 2014 at 13:37

Found one:

This looks like the same code as the one I posted several years earlier. Where did you get it from? – Mainly 20/2, 2019 at 2:45
