Tri-State checkboxes on QTreeView with QSortFilterProxyModel

[tmmak]

I created a QTreeView. Each node of the tree has a tri-state checkbox. Then I create another instance of the tree using QSortFilterProxyModel. The new instance displays a subset of the tree based on the selected node on the original tree.

The tri-state checkboxes on both trees work fine. However, when a checkbox state is changed in one tree, the same checkbox is also changed in the other tree. I can understand this is because both trees access the same model.

Is there a way to have the states of the checkboxes on the two trees to be different?

Thanks,
TM

Not with QSortFilterProxyModel, because all state is set in the source model.

You have to implement your own proxy model to do this.
