Selection of audio file with component identification

In the current version of mGIS interface, which audio file is to play for a layer of components, is defined inside the program. After the last discussion with our Geography partners, seems like all of the students should have an identical view of a single map data. So individualization of mGIS interface may not be an issue. But if we want the educators able to select audio files for different layers, we should provide some facilities for doing this.

Using style sheet may be an option. I can think of it as a table lookup process. Here I am describing how we can incorporate style sheet:

We already have mouse motion event listener registered with the map components. Whenever the mouse pointer points a pixel, this listener triggers the event and calls the event performed method.

eventPerformed(mouseMotion event){

String layerName = identifyMapLayer(event.getX, event.getY);
String audioFileName = style.Layer(layerName);


}

Here the identifyMapLayer returns the layer name and the style sheet then look up the audio file name for the corresponding layer. We know how to define the identifyMapLayer method. Now we need to find out a way to define a style sheet.

In this way the style sheet will have no dependency on arcGIS components and events. If we think about this from the modular point of view, this style sheet can be built independently without having much integration cost. I hope the educators of mGIS interface will be able to select or change the audio files for different layers.
