The Blue theme is thedefault theme. It also creates a widget group, but that is not shown in Figure 5-3.• lightshow is the reference to the lightshow applet. Only the lightshow applet is shown, buta similar instantiation sequence applies to all of applets.• wg is a widget group created by the lightshow applet. This code calls the code in a Layerobject to render its image to the display.• If the exit control is clicked in the theme, run() exits and the lotion application ends.Figure 5-4 on page 5-9 shows the control flow related to selecting and running the lightshowapplet. The theme passes user events to the lightshow widget which then calls the lighshowapplication to process the user action.ARM DUI 0527A-02a Copyright © 2010 ARM.
