Ahh darn, the only app that diverges. Oke, Windows does indeed show
the application name.
However, windows is doing something strange with the title.

QWidget has http://qt-project.org/doc/qt-4.8/qwidget.html#windowTitle-prop
and that one is used in the title when it's set.
QApplication has setApplicationName and that one is _not_ being used.
Rather the executable filename (without the extension) is used.

So: it's only being set afaict when setWindowTitle from QWidget is
called otherwise it's the executable name minus extension.

As for messages. If you don't provide a title
(QMessageBox::warning(...)) then the application executable minus
extension is the title. Even if you have set the application window
title to something else (just tested that). If you do set a title for
the message dialog with QMessageBox::warning it's being used as the
title.. obviously ;)

Hope that helps a bit better.

Cheers,
Mark
