Qt download example

Can this be converted to a function for an existing project? I'm struggling with how to do so. It works great as a standalone program.

Hi
Yes, it should be reusable without much fuss. except, make sure to place the class definitionsin a .h file
as sample uses trick to get the moc tool (to allow for signals) to process the .CPP file.
So best to include in a .h instead for reuse.
Then there is the scope thing to be aware of.

in sample, it does

int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);

    DownloadManager manager;
    QTimer::singleShot(0, &manager, SLOT(execute()));

    app.exec();
}

This you cannot directly use in function as manager will run out of scope and die so you have to new it.

    DownloadManager *manager = new DownloadManager(this);
    QTimer::singleShot(0, manager, SLOT(execute()));

Else please tell what is causing issues so we can help.
