This Communications application demo (viewed as a Java applet) was constructed using SL-GMS J/Developer and the network mapping extension SL-GMS J/Net. This applet is highly compact, portable and performs exceptionally well.
It is possible to zoom and pan to various locations: Right click and select ' Zoom' and click on any area of the map. Hold down the SHIFT key and click to zoom out. Right click and select 'Pan', then drag the map holding down the left mouse button. (Note: It is not possible to 'Pan' at 100% visibility.)
This applet is ~286K, including the Nodes and Connectors, and all interactive behaviors.
The Nodes, Connectors and Map Background are instantiated programmatically from an XML file.
This demo could easily be extended to develop a more complete Communications application.
