Questions regarding GTK4 ColumnView

Hi there,

I have trouble understanding how to sort the following columnview (minimum working example):

My follow-up question would be:
If ColumnView uses a single model for multiple columns, and StringList is a list of strings, not a list of list. Therefor I’m probably expected to implement the ListModel interface in an own class for multiple columns?

Many thanks in advance.

Yes, you should implement your own multi-columns ListModel class now,

@esodan 's library: Daniel Espinosa Ortiz / libvda · GitLab ( is a great example to show this scene.
