QTreeWidget如何去掉虚线，红线地方的虚线如何去掉？
m_treeWidget = new QTreeWidget;
m_treeWidget->setStyleSheet("QTreeView::branch{image:none;}"); 这条代码好像没有效果。
m_treeWidget->setRootIsDecorated(false); //去掉虚线边框
QTreeWidgetItem *cities = new QTreeWidgetItem(m_treeWidget);
cities->setText(0, tr("Cities"));
m_treeWidget->setStyleSheet("QTreeView::branch{image:none;}");
QTreeWidgetItem *osloItem = new QTreeWidgetItem(cities);
osloItem->setText(0, tr("Oslo"));
osloItem->setText(1, tr("Yes"));
osloItem->setChildIndicatorPolicy(QTreeWidgetItem::DontShowIndicatorWhenChildless);
QTreeWidgetItem *planets = new QTreeWidgetItem(m_treeWidget, cities);
planets->setText(0, tr("Planets"));
