Properties

Detailed Description

Each ValueSpaceSubscriber element represents a single value or path in the Value Space. The path is set using the path property.

Note that unlike the C++ class QValueSpaceSubscriber, the QML element has no default path. A path must be set before the subscriber will connect to the Value Space and begin receiving notifications.

 ValueSpaceSubscriber {
     id: nowPlaying
     path: "/applications/mediaplayer/now-playing"
 }

The value is accessed using the value property:

 Text {
     text: nowPlaying.value
 }
