从给定列表创建QTreeView层次结构

from PyQt5.QtWidgets import QApplication, QTreeView, QStandardItemModel, QStandardItem

app = QApplication([])

tree_view = QTreeView()

model = QStandardItemModel()

def create_tree(items, parent_item):
    for item in items:
        item_obj = QStandardItem(item['name'])
        parent_item.appendRow(item_obj)
        if 'children' in item:
            create_tree(item['children'], item_obj)

items = [
    {
        'name': 'Item 1',
        'children': [
            {
                'name': 'Item 1.1',
                'children': [
                    {'name': 'Item 1.1.1'},
                    {'name': 'Item 1.1.2'}
                ]
            },
            {
                'name': 'Item 1.2'
            }
        ]
    },
    {
        'name': 'Item 2'
    }
]

create_tree(items, model)

tree_view.setModel(model)

tree_view.show()

app.exec_()
