My default window manager has always been using Beryl and there is no problem. Whether it is development (Java) or general applications. When developing Java Desktop applications, I usually use SWT, AWT, and swing for a long time. Today I used them and suddenly found a problem: When Beryl is enabled for AWT/swing, the control cannot be displayed, that is, it cannot be drawn, and it is depressing. To Java

Perhaps you used to use AWT to design a graphical user interface (GUI), how do you feel? Now that JAVA2 offers a swing pack that shows you a richer set of features, the interface you use to design it will be friendlier, so let's take a look. Before you designed a small application to expand the applet (Java.applet.Applet); Now to use swing packs, you want to extend JApplet (Javax.swing.JApplet) Let's look at an example of an extended JApplet applet a

gui--graphical user Interface GUI. Introduction: AWT is the first GUI class library package in the Java language. Java is a platform-independent programming language, but the GUI is often dependent on a specific platform, Java uses the appropriate technology to enable AWT to provide applications independent of the Machine platform interface, which ensures that the same program's GUI on different machines
