# RCWeb RSS News Control

**RSS News Control** is the phone-friendly companion to the **rss-news** viewer. It shows what is currently on the display, lets you cycle through the loaded screens, and configures the viewer's RSS source addresses.

## What it does

- Lists every article on the current screen with title, snippet, source and timestamp
- Provides large touch buttons for **Prev**, **Play / Pause**, and **Next**
- Edits the viewer's active RSS feed URLs
- Provides a **Refresh headlines** action that reloads feeds on the viewer

## RCWeb communication

The viewer owns all news state. The control sends commands to the viewer:

```javascript
rc.sendFunctionCall("rss-news", "rssNewsViewer.prev");
rc.sendFunctionCall("rss-news", "rssNewsViewer.next");
rc.sendFunctionCall("rss-news", "rssNewsViewer.toggle");
rc.sendFunctionCall("rss-news", "rssNewsViewer.refresh");
rc.sendFunctionCall("rss-news", "rssNewsViewer.setSources", ["https://feeds.bbci.co.uk/news/rss.xml"]);
rc.sendFunctionCall("rss-news", "rssNewsViewer.requestState", rc.client);
```

The viewer pushes snapshots to controls through the global callback:

```javascript
rssNewsControl.receiveState(snapshot);
```

The snapshot contains the active screen index and total, the play state, the active RSS sources, source errors and the current screen contents.
