How do I deal with "Project Files" in my Qt application? <p>My Qt application should be able to create/open/save a single "Project" at once. What is the painless way to store project's settings in a file? Should it be XML or something less horrible?</p> <p>Of course data to be stored in a file is a subject to change over time.</p> <p>What I need is something like <code>QSettings</code> but bounded to a <strong>project</strong> in my application rather than to the whole application.</p>
