Qt 问题 判断QTreeWidget的子节点的父节点是否可见

bool JudgeParentItemVisible(QTreeWidgetItem * pLayerItem)
{
	bool bVisible = true;
	QTreeWidgetItem * pParentItem = (QTreeWidgetItem *)pLayerItem->parent();	//获取父节点
	if (pParentItem != NULL)	//父节点不为空
	{
		if (pParentItem->checkState(0) == Qt::CheckState::Unchecked)	//如果不可见返回false
		{
			bVisible = false;
			return bVisible;
		}
		bVisible = JudgeParentItemVisible(pParentItem);	//可见继续判断父节点的可见性
	}
	else	//说明是一级节点
	{
		if (pLayerItem->checkState(0) == Qt::CheckState::Unchecked)	//如果不可见返回false
		{
			bVisible = false;
		}
	}
	return bVisible;
}
