Get the strings from a List of QtreeView

c++, qt, qtreeview

Solution

QStringList strings = extractStringsFromModel(Tree->model(), QModelIndex());

Implementation of extractStringsFromModel

QStringList extractStringsFromModel(QAbstractItemModel *model, const QModelIndex &parent)
{
    QStringList retval;


    int rowCount = model->rowCount(parent);

    for(int i = 0; i < rowCount; ++i)
    {
        QModelIndex idx = model->index(i, 0, parent);

        if(idx.isValid())
        {
            retval << idx.data(Qt::DisplayRole).toString();
            retval << extractStringsFromModel(model, idx);
        }
    }

    return retval;
}

This recursive function will extract ALL texts from your model. If you want to get "specific" data, then you should add some filtering. But basicly it will go through whole tree.

Problem

I want to get the Strings from a List of QtreeView. In my qtreeview i have: ``` [*] Node1 [*] Subnode1_1 test_1 test_2 [*] Node2 test_3 [*] Subnode2_1 test_4 test_5 ``` and I want to get Strings: test_1, test2, test3, test4, test5 To start a request in a database. The only thing i found is get the String from the node you selected. by : `Tree->model()->itemData(m_listOfModelIndex.at(0))[Qt::DisplayRole].toString()` Thanks
