I've a QMap
object and I am trying to write its content to a file.
QMap<QString, QString> extensions;
//..
for(auto e : extensions)
{
fout << e.first << "," << e.second << '\n';
}
Why do I get: error: 'class QString' has no member named 'first' nor 'second'
Is e
not of type QPair
?
If you want the STL style with first
and second
, do this:
for(auto e : extensions.toStdMap())
{
fout << e.first << "," << e.second << '\n';
}
If you want to use what Qt offers, do this:
for(auto e : extensions.keys())
{
fout << e << "," << extensions.value(e) << '\n';
}
