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

There has to be exactly one [http://doc.qt.nokia.com/latest/qapplication.html Qt::Application] object in every GUI application that uses Qt.
[http://doc.qt.nokia.com/latest/qapplication.html Qt::Application] manages various application-wide resources, such as the default font and cursor.

Jokaisessa graafisessa käyttöliittymäsovelluksessa, joka käyttää Qt:tä, on tarkalleen vain yksi Qt::Application-objekti. Qt::Application hallinnoi useita sovellustason resursseja, kuten oletuskirjasimia ja kohdistinta.
