简单问题,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路径。
我这样称呼方法:
xmlwriter-> write_settings( “./的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;
}
}
答案 0 :(得分:1)
您没有正确传递参数,因此您可能会调用QFile::open
的多态版本
试试这个:
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;
}
