Downloading a file and saving in a path

[Santosh Reddy]

You are trying to create two MainWindows, both will run simultaneously, if you want the 2nd MainWindow to wait until first one is done then

#include <QtGui/QApplication>
#include "mainwindow.h"
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
 
    w.show();
    a.exec();//<<<<<<<<<<<<<<<<<<<<
 
 
    MainWindow dl;
    dl.setTarget("/mnt/jffs2/Synch.xml");
 
    dl.download();
 
    return 0;//<<<<<<<<<<<<<<<<<<<<
}

#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;

    w.show();
    a.exec();//<<<<<<<<<<<<<<<<<<<<


    MainWindow dl;
    dl.setTarget("/mnt/jffs2/Synch.xml");

    dl.download();

    return 0;//<<<<<<<<<<<<<<<<<<<<
}

also the error you mentioned (altually warnning) is because you commented out that solt in the code
