Actually, I wasn't suggesting that you change to windows-style
"\".  I just used them out of laziness when I did my test.

I do think that his using an instance of QFileDialog is a red herring.
I agree that it is better style to call the static member function with

   QFileDialog::getOpenFileName(...);

rather that with

  instanceOfAQFileDialog.getOpenFileName(...);

but my understanding is that these two calls are actually the same.

But, unless there is a typo in what Yogesh posted, how could it be
his code?

It's very odd.  I don't see how there could be a difference between
passing a string litereal and a QString to QFileDialog::getOpenFileName.
(And I didn't see any difference in my test.)

Thanks.
