    \brief API wrapper for QML message dialog implementations
    \since 5.2
    \internal

    AbstractMessageDialog provides only the API for implementing a message dialog.
    The implementation (e.g. a Window or preferably an Item, in case it is
    shown on a device that doesn't support multiple windows) can be provided as
    \l implementation, which is the default property (the only allowed child
    element).
*/

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

    This signal is emitted by \l accept().
*/

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

    This signal is emitted by \l reject().
*/

/*!
    \class QQuickMessageDialog
    \inmodule QtQuick.Dialogs
    \internal

    The QQuickMessageDialog class is a concrete subclass of
    \l QQuickAbstractMessageDialog, but it is abstract from the QML perspective
    because it needs to enclose a graphical implementation. It exists in order
    to provide accessors and helper functions which the QML implementation will
    need.
