Let's starting by importing the necessary PySide2 classes and python sys module: 我们还将它的选择模式设置为单选模式。然后，我们连接clicked信号到on_clicked函数，以便在用户单击TreeView的项目时调用该函数。最后，在on_clicked函数中，我们使用QModelIndex的data()方法来获取所选项的文本，并打印出它的索引和文本。当用户单击Tree View中的项时 treeView->setContextMenuPolicy(Qt::CustomContextMenu); Then you can connect to the QWidget::customContextMenuRequested(const QPoint&) signal and show your context menu. hank hank.
