Message definition (Development/Tutorials/Qt4 Ruby Tutorial/Chapter 01)

'''<tt>app</tt>''' is this program's [http://doc.qt.nokia.com/latest/qapplication.html Qt::Application] instance. It is created here.
We pass '''<tt>ARGV</tt>''' to the [http://doc.qt.nokia.com/latest/qapplication.html Qt::Application] constructor
so that it can process certain standard command-line arguments (such as '''<tt>-display</tt>''' under X11).
All command-line arguments recognized by Qt are removed from '''<tt>ARGV</tt>'''.

app on tämän ohjelman Qt::Application-ilmentymä. Se luodaan tässä. Välitämme ARGV kohteelle Qt::Application-konstruktori, jotta se voi käsitellä tiettyjä vakiokomentoriviargumentteja (sellaisia kuin -display X11:n alla). Kaikki Qt:n tunnistamat komentoriviargumentit poistetaan kohteesta ARGV.
