Why is my QTreeView(+ custom qabstractitemmodel) empty?
Using this QAbstractItemModel I get an empty QTreeView. I've been banging my head on-and-off for months now with this. Could anyone see what I'm missing?
When I change a line here according to the comment, start using the simple QObject-treemodel as copied from Johan Thelin's book Foundations of Qt Development, QTreeView starts functioning as expected. This leads me to think my model is somehow flawed, but I can't figure out how.
HI and welcome to devnet,
One fishy thing in your data function: you have
if (!role != Qt::DisplayRole)why do you have an exclamation mark before
Goddammit that's it, now it works. Unbelievable how that small exclamation mark caused a few month's worth of grief and wtfs.
Thank you :)
