from PyQt5.QtWidgets import QApplication, QTreeWidget, QTreeWidgetItem, QComboBox

app = QApplication([])

# 创建QTreeWidget
treeWidget = QTreeWidget()
treeWidget.setColumnCount(2)

# 创建QTreeWidgetItem并添加到QTreeWidget
item = QTreeWidgetItem(treeWidget)
item.setText(0, "Item 1")

# 设置第二列的标志为Qt::ItemIsEnabled，即不可编辑
item.setFlags(item.flags() & ~Qt.ItemIsEnabled)

# 创建QComboBox并添加到QTreeWidgetItem的第二列
comboBox = QComboBox()
comboBox.addItem("Option 1")
comboBox.addItem("Option 2")
treeWidget.setItemWidget(item, 1, comboBox)

# 隐藏QComboBox
comboBox.setVisible(False)

# 显示QTreeWidget
treeWidget.show()

app.exec_()
