Class AudioDemoPanel

java.lang.Object
ca.corbett.extras.demo.panels.PanelBuilder
ca.corbett.extras.demo.panels.AudioDemoPanel
All Implemented Interfaces:
AudioPanelListener
public final class AudioDemoPanel extends PanelBuilder implements AudioPanelListener
Provides a way to test out the AudioUtils, and more specifically, the AudioWaveformPanel. Apologies: this code predates swing-forms and is therefore a little ugly. One day I'll sit down and rewrite it to get rid of all the GridBagLayout stuff.
