如何遍历QTreeWidget上面的QTreeWidgetItem

如何遍历QTreeWidget上面的QTreeWidgetItem

QTreeWidget下有topLevelItem，每个QTreeWidgetItem下child，看看帮助文本档

  QTreeWidgetItemIterator it(QTreeWidget);     while (*it) {          //do something like          (*it)->text(0);         ++it;     }

QTreeWidgetItemIterator it(QTreeWidget);
应该是这样的：QTreeWidgetItemIterator it(object);   //QTreeWidget object
