if (QxtConfirmationMessage::confirm(this, tr("Confirm"), text) == QMessageBox::No)

\bold {Note:} QCoreApplication::organizationName and QCoreApplication::applicationName
are used for storing settings. In case these properties are empty, \bold "QxtWidgets" and
\bold "QxtConfirmationMessage" are used, respectively.
