54
55 AbstractMessageDialog provides only the API for implementing a message dialog.
56 The implementation (e.g. a Window or preferably an Item, in case it is
57 shown on a device that doesn't support multiple windows) can be provided as
58 \l implementation, which is the default property (the only allowed child
59 element).

85 because it needs to enclose a graphical implementation. It exists in order
86 to provide accessors and helper functions which the QML implementation will
87 need.
