Well, now I get errors:
javassist.CannotCompileException: by java.lang.LinkageError: duplicate class
definition: javax/swing/JLabel
| at javassist.CtClass.toClass(CtClass.java:900)
| at javassist.CtClass.toClass(CtClass.java:860)
| at AASwing.main(AASwing.java:40)
| Exception in thread "main"
The exception is thrown at the Class c = cc.toClass(); line.
the code is as follows:
ClassPool pool = ClassPool.getDefault();
| CtClass cc = pool.get("javax.swing.JLabel");
| CtMethod m = cc.getSuperclass().getDeclaredMethod("paint");
|
m.insertBefore("((java.awt.Graphics2D)$1).setRenderingHint(java.awt.RenderingHints.KEY_ANTIALIASING,
java.awt.RenderingHints.VALUE_ANTIALIAS_ON); super.paint($1);");
| Class c = cc.toClass();
|
| JLabel b = (JLabel)c.newInstance();
How do I replace the JLabel component?
