Example for QMLTree QModelIndex to C++
This is an example on how to use QModelIndex in a Treeview exchanging data from C++ to QML and back.
It uses quite an easy tree model, which is published to QML. The purpose ist to send back the information of the clicked item to C++.
There are qDebug statements showing the address, content and parent of each treeItem.
On clicking a treeItem in the TreeView QML calls a c++ func void TreeModel::showQModelIndex(const QModelIndex &index) const
which prints the chosen TreeItem via qDebug() in the console.
There are two main QML files:
- main.qml which uses the Qt TreeviewDelagate
- mainOwnDelegate which creates its own TreeviewDelegate
The chosen TreeviewDelegate can be swapped in the main.cpp.
