Btw, you can also use sheets with application-modal dialogs.  Example:

   QFileDialog diag(this);
   diag.setWindowModality(Qt::WindowModal);
   diag.exec();

exec() makes the dialog modal, but it's still a sheet.  I actually use 
this because my application is not multi-document based and exec() is 
simpler to use than open() since it blocks.

I'm not sure if this is intended to be used like this, but it works. 
Note that you can do this with any dialog, not just QFileDialog.
