Class StockNewsApp

java.lang.Object
  edu.berkeley.guir.ptk.PTK

All Implemented Interfaces:

PEventReceiver

public class StockNewsApp

extends PeripheralDisplay

Stock News Ticker application: this is an example application using the PTK. It is the remotely distributed version of the Stock News Ticker application. It is a ticker that displays two rows of text information: stock quotes on top and CNN news headlines on bottom. The text scrolls from right to left. It fades in and out when changes are made. It interrupts the user when a certain headline appears or stocks for a company rise or fall below a certain level. The interruption transition is to flash the text a few times.

See the code and inline code comments for an example of how to write a peripheral display.

To run this class, you must do the following:

1. Run the PTK Server: PDiscovery
2. Run the news and stock input classes: NewsInput, StockInput
3. Run this class.
