Porting QListView to QTreeWidget

[Sohoquetaros]

Hello together,

I'm trying to remove all my QT3 code and port it to some "real" QT4 classes (not the Q3 compatibility classes). Everything works fine except one problem I can't solve:

I was changing the number of columns in a QListView dynamically using "removeColumn(int column)" but I didn't find any corresponding function within the QTreeWidget class.

Does anyone know how to change the number of columns (in my case only removing some columns) in a QTreeWidget?

Thanks a lot for your help !

Maybe you're searching for QTreeWidget::setColumnCount()?

If you want to show a subset of a given set of columns (and switch between these) you could use setColumnHidden() to hide the unused columns.

Thanks a lot - the second solution was the one I was looking for.

Thank you for your fast help !
