    QtMessageDialog provides a means to instantiate and manage a QMessageBox.
    It is not recommended to be used directly; it is an implementation
    detail of \l MessageDialog in the \l QtQuick.Dialogs module.

    To use this type, you will need to import the module with the following line:
    \code
    import QtQuick.PrivateWidgets 1.1
    \endcode
*/

/*!
    \qmlsignal QtQuick::Dialogs::MessageDialog::accepted

    The \a accepted signal is emitted when the user has pressed the OK button
    on the dialog.

    Example:

    \qml
    MessageDialog {
        onAccepted: { console.log("accepted") }
    }
    \endqml

    The corresponding handler is \c onAccepted.
*/

/*!
    \qmlsignal QtQuick::Dialogs::MessageDialog::rejected

    The \a rejected signal is emitted when the user has dismissed the dialog,
    either by closing the dialog window or by pressing the Cancel button.

    The corresponding handler is \c onRejected.
