How do I make my own QDialog working like for example QFileDialog

It doesn't have to be virtual to reimplement and use it of course... Virtuality is only needed when something else calls the method.

True, but it's still a bad practice to shadow non-virtual methods.

"It depends" I don't see anything improper in reimplementing QDialog::exec() I know it's possible that someone will want to call it after casting to QDialog, but hey! let's try our luck Of course it's better to avoid such risks...
