No one said you are what you just described! I said you don't seem to be aware that changing properties on an instance has no effect on a successive static method call (which by nature can't access the members of a class instance). One can be an excellent programmer, but still be ignorant of (some) basic properties of a given language/concept. But in any case, that does not make a [words not repeated here] of anyone! We are all here to learn, now aren't we.

No, it's not a "gray" area, and personally I don't discourage you to use an instance of QFileDialog. Depending on the context it might be more useful (more flexible). There is *nothing* wrong with that! Just don't call a *static* method and expect it to behave according to the properties you have set on the *instance*, that's all.

Well, whatever you prefer. I still strongly suggest you use '/' in hard-coded paths because Qt understands that on *every* platform (to be honest it might even parse '\\' on a Unix platform correctly, but that is probably an "undocumented feature" ;)

Also take a note of the static method

  http://doc.trolltech.com/4.6/qdir.html#toNativeSeparators

which is very useful when it comes to *displaying* paths to the user.

Well, no objections to that ;)

You're very welcome to do so! And with Qt happiness /does/ stay for long ;)
