您可以使用以下代码来在程序中将QTreeWidget的所有项目默认展开:
```python
def expand_all_items(tree_widget):
"""
A function to expand all the items in the given QTreeWidget.
"""
for i in range(tree_widget.topLevelItemCount()):
item = tree_widget.topLevelItem(i)
expand_recursively(item)
def expand_recursively(item):
"""
A recursive function to expand all the child items of the given QTreeWidgetItem.
"""
item.setExpanded(True)
for i in range(item.childCount()):
child_item = item.child(i)
expand_recursively(child_item)
```
在您的主程序中,您可以将QTreeWidget的对象传递给expand_all_items函数,如下所示:
```python
tree_widget = QTreeWidget()
# Add items to the tree_widget
expand_all_items(tree_widget)
```
这将展开QTreeWidget中的所有项目。
