简单的问题,我只是无法打开/创建文件。它应该将 xml 文件中的一些设置保存到给定的路径。
我这样调用方法:
xmlwriter->write_settings("./settings.xml");
int XmlWriter::write_settings(QString path)
{
qDebug() << "Path is: " + path;
QDomDocument document;
QDomElement root = document.createElement("settings");
document.appendChild(root);
QDomElement node;
node.setAttribute("name", "Its me!");
node.setAttribute("series", "25");
node.setAttribute("PMT", "200");
root.appendChild(node);
QFile file(path);
if(!file.open(QIODevice::ReadWrite, QIODevice::Text))
{
qDebug() << "Opening file failed!";
return 1;
}
else
{
QTextStream stream(&file);
stream << document.toString();
file.close();
qDebug() << "wrote file to " + path;
return 0;
}
}
