The radio tuner, \l QRadioTuner or the \l Radio QML type, which handles control of the radio hardware as well as tuning. The other is the radio data component, either \l QRadioData or the \l RadioData QML type, which gives access to RDS information. \section1 Radio Implementation Details The actual level of support depends on the underlying system support. It should be noted that only analog radio is supported, and the properties of the radio data component will only be populated if the system radio tuner supports RDS. \section1 Examples There are two examples showing the usage of the Radio API. One shows how to use the QRadioTuner class from C++. The other shows how to implement a similar application using QML and \l Radio. \section2 Radio Example This image shows the example using the QRadioTuner API. \image radio-example.png The example reads the frequency from the radio tuner, and sets the "Got Signal" text based on the signal strength. The buttons allow the user to tune and scan up and down the frequency band, while the slider to the side allows volume adjustments. Only the FM frequency band is used in this example. \section2 Declarative Radio Example \image declarative-radio-example.png This example has the same functionality of the regular radio example mentioned above, but it includes a nice horizontal dial showing the position of the current frequency inside the band. \section1 Reference documentation \section2 C++ Classes \annotatedlist multimedia_radio \section2 QML Types \annotatedlist multimedia_radio_qml */
