This video demonstrates the discovery and communication between widgets.
The three examples are run within one player, but the same demonstration can be done between two players on the same machine or on different devices.
Warning: the video is quite large, so you should be prepared to switch to 1080p and full screen to see anything.
What is shown:
– starting a light widget and a switch widget, and clicking on the switch turns the light widget on, showing that the two have discovered each other and communicated
– starting a photo catalog widget and a photo display widget
– starting a radio widget and a radio control panel widget
