QHttp and QTemporaryFile

[maximAL]

hi,
i am trying to temporarily download a file for further processing. but for some reason QHttp::get does not like QTemporaryFile, whilst it works with a normal QFile.
The temporary file actually gets created but remains empty.

#include <QtCore>
#include <QtNetwork/QHttp>
 
#include <cstdio>
 
int main(int argc, char* argv[])
{
    QCoreApplication app(argc, argv);
    //QFile file("EDDC.TXT"); // works
    QTemporaryFile file; // doesn't work
    //file.open(); doesn't help
    QHttp http;
    http.setHost("weather.noaa.gov");
    http.get("/pub/data/observations/metar/decoded/EDDC.TXT", &file);
    app.connect(&http, SIGNAL(done(bool)), &app, SLOT(quit()));
    app.exec();
    getc(stdin); // block so the temporary file won't be deleted yet
}

#include <QtCore>
#include <QtNetwork/QHttp>
 
#include <cstdio>

int main(int argc, char* argv[])
{
    QCoreApplication app(argc, argv);
    //QFile file("EDDC.TXT"); // works
    QTemporaryFile file; // doesn't work
    //file.open(); doesn't help
    QHttp http;
    http.setHost("weather.noaa.gov");
    http.get("/pub/data/observations/metar/decoded/EDDC.TXT", &file);
    app.connect(&http, SIGNAL(done(bool)), &app, SLOT(quit()));
    app.exec();
    getc(stdin); // block so the temporary file won't be deleted yet
}

problem solved: i had to call flush() on the file before accessing it. no idea though, why it only occured when creating a temporary file.
