- \brief A confirmation message.
-
- QxtConfirmationMessage is a confirmation message with checkable
- <b>"Do not show again."</b> option. A checked and accepted confirmation
- message is no more shown until reseted.
-
- Example usage:
- \code
- void MainWindow::closeEvent(QCloseEvent* event)
- {
- static const QString text(tr("Are you sure you want to quit?"));
- if (QxtConfirmationMessage::confirm(this, tr("Confirm"), text) == QMessageBox::No)
- event->ignore();
- }
- \endcode
-
- \image html qxtconfirmationmessage.png "QxtConfirmationMessage in action."
-
- \note \b QCoreApplication::organizationName and \b QCoreApplication::applicationName
- are used for storing settings. In case these properties are empty, \b "QxtGui" and
- \b "QxtConfirmationMessage" are used, respectively.
-
- \note Requires Qt 4.2 or newer.
