\brief The RadioData element allows you to access RDS data from a QML application.
|
|
\ingroup qml-multimedia
|
|
\inherits Item
|
|
|
|
This element is part of the \bold{QtMultimedia 5.0} module.
|
|
|
|
The \c RadioData element is your gateway to all the data available through RDS. RDS is the Radio Data System
|
|
which allows radio stations to broadcast information like the \l stationId, \l programType, \l programTypeName,
|
|
\l stationName, and \l radioText. This information can be read from the \c RadioData element. It also allows
|
|
you to set whether the radio should tune to alternative frequencies if the current signal strength falls too much.
|
|
|

You use \c RadioData together with the \l Radio element. The properties of the RadioData element will reflect the
|
|
information broadcast by the radio station the Radio element is currently tuned to.
