QTreeView - update parent item

folibis

I have a tree (QTreeView) in my program.
It looks like QtDesigner property editor when parent item text contains text from children, for example

so, I need update parent when children's text changed. How can I do that?

Hello,
welcome to Qt forum :).

Do You store Yours internalc data in some some parent-children structure? If yes, You should update first this model and then emit signal "QAbstractItemModel::dataChanged(...)":http://qt-project.org/doc/qt-5.0/qtcore/qabstractitemmodel.html#dataChanged Then Your parent will be updated.

If not, please give some more details about implmentation details,

Robert
