怎么在tabwidget中添加treewidget和tablewidget

要在QTabWidget中添加QTreeWidget和QTableWidget，可以按照以下步骤进行操作：

1. 创建QTabWidget对象

tab_widget = QTabWidget()

2. 创建QTreeWidget对象和QTableWidget对象

tree_widget = QTreeWidget()
table_widget = QTableWidget()

3. 将QTreeWidget对象和QTableWidget对象添加到QTabWidget对象中

tab_widget.addTab(tree_widget, "Tree Widget")
tab_widget.addTab(table_widget, "Table Widget")

4. 设置QTreeWidget对象和QTableWidget对象的属性

tree_widget.setHeaderLabels(["Name", "Type", "Size"])
table_widget.setColumnCount(3)
table_widget.setHorizontalHeaderLabels(["Name", "Type", "Size"])

5. 将QTabWidget对象添加到主窗口中

main_layout.addWidget(tab_widget)

完整的代码示例：

from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QTabWidget, QTreeWidget, QTableWidget

app = QApplication([])
window = QWidget()
main_layout = QVBoxLayout()

# 创建QTabWidget对象
tab_widget = QTabWidget()

# 创建QTreeWidget对象和QTableWidget对象
tree_widget = QTreeWidget()
table_widget = QTableWidget()

# 将QTreeWidget对象和QTableWidget对象添加到QTabWidget对象中
tab_widget.addTab(tree_widget, "Tree Widget")
tab_widget.addTab(table_widget, "Table Widget")

# 设置QTreeWidget对象和QTableWidget对象的属性
tree_widget.setHeaderLabels(["Name", "Type", "Size"])
table_widget.setColumnCount(3)
table_widget.setHorizontalHeaderLabels(["Name", "Type", "Size"])

# 将QTabWidget对象添加到主窗口中
main_layout.addWidget(tab_widget)

window.setLayout(main_layout)
window.show()
app.exec_()
