To create an applet, you must first create + * a context object in which it will run. There can be several applets and + * contexts in operation at a given time, for example in a web browser there + * would be one context object for each web page. Applets in the same context + * can communicate with each other, applets in different contexts cannot. + * Once you have created a KJavaAppletContext, you can create as many + * applets in it as you want. + * + * Once you have created the applet widget, you should access the applet() method + * to call the various setXXX methods to configure the applet, + * They correspond to the HTML tags used to embed applets in a web page. + * Once the applet is configured, call the create() method to set things in motion. + * The applet is running when it first appears, but you can start or stop it + * when you like (for example if it scrolls off the screen). + * + * This widget works by using the KJavaAppletServer, which fires off a + * Java server process with which it communicates using the + * KDE Java Applet Server (KJAS) protocol over stdin and stdout. + * The applet windows are swallowed and attached to the QWidget, but they are + * actually running in a different process. This has the advantage of robustness + * and reusability. The details of the communication are hidden from the user + * in the KJASAppletServer class. Normally only a single server process is used for + * all of the applets in a given application, this is all sorted automatically. + * The KJAS server is 100% pure Java, and should also prove useful for people + * wishing to add java support to other systems (for example a perl/Tk binding + * is perfectly feasible). All you need to do is implement the protocol and + * (optionally) swallow the applet windows. + * + * The applet support in KDE is still dependent on the KWin Window Manager. The + * applet swallowing will not work under other Window Managers. Hopefully this + * will be fixed in the future. + * + * For a description of the KJAS protocol, please see the KJAS_GRAMMAR.txt file. + * + * @author Richard J.
