QT笔记- QTreeView项text遍历

    void traverseTreeView(const QModelIndex &index, const QAbstractItemModel *model, QStringList &stringList) {
        if (!index.isValid()) {
            return;
        }

        // 获取当前项的文本并添加到 QStringList 中
        QString text = model->data(index, Qt::DisplayRole).toString();
        if (!text.isEmpty()) {
            stringList.append(text);
        }

        // 递归遍历子项
        for (int row = 0; row < model->rowCount(index); ++row) {
            for (int col = 0; col < model->columnCount(index); ++col) {
                traverseTreeView(model->index(row, col, index), model, stringList);
            }
        }
    }

    QStringList getAllItemsText(QTreeView *treeView) {
        QStringList stringList;
        QAbstractItemModel *model = treeView->model();

        if (model) {
            // 从根节点开始遍历
            traverseTreeView(treeView->rootIndex(), model, stringList);
        }

        return stringList;
    }
