I have to edit Labels that are being defined inside the constructor of a class.
Because those labels use getters and setters for the text, I decided to redefine them at the end of the constructor.
public class StaticPraxMMod {
private static final String PRAXFRAME = "com.praxemu.client.graphics.widgets.PraxFrame";
public static void main(String[] args) throws Exception {
ClassPool classPool = ClassPool.getDefault();
addEVLink(classPool);
}
private static void addEVLink(ClassPool classPool) throws NotFoundException, CannotCompileException, IOException {
CtClass praxFrameClass = classPool.get(PRAXFRAME);
CtConstructor praxFrameConstructor = praxFrameClass.getConstructors()[0]/*(new CtClass[] {})*/;
//praxFrameClass.addConstructor(praxFrameConstructor);
praxFrameConstructor.insertAfter("localLabel25 = new de.matthiasmann.twl.Label(new StringBuilder().append(paramsuper.õo0000().o00000(null.Ô00000)).append(\"\").toString() + \"peanuts\");\n"
"localLabel26 = new de.matthiasmann.twl.Label(new StringBuilder().append(paramsuper.õo0000().o00000(null.class)).append(\"\").toString() + \"peanuts\");\n" +
"localLabel27 = new de.matthiasmann.twl.Label(new StringBuilder().append(paramsuper.õo0000().o00000(null.õ00000)).append(\"\").toString() + \"peanuts\");\n" +
"localLabel28 = new de.matthiasmann.twl.Label(new StringBuilder().append(paramsuper.õo0000().o00000(null.ÓO0000)).append(\"\").toString() + \"peanuts\");\n" +
"localLabel29 = new de.matthiasmann.twl.Label(new StringBuilder().append(paramsuper.õo0000().o00000(null.interface)).append(\"\").toString() + \"peanuts\");\n" +
"localLabel25.setTheme(\"label-value\");\n" +
"localLabel26.setTheme(\"label-value\");\n" +
"localLabel27.setTheme(\"label-value\");\n" +
"localLabel28.setTheme(\"label-value\");\n" +
"localLabel29.setTheme(\"label-value\");");
//praxFrameClass.toBytecode();
praxFrameClass.writeFile(".");
}
}
When running it, I get this :
Exception in thread "main" javassist.CannotCompileException: [source error] no such field: localLabel25

I tried adding the full package path to labels but it doesn't change a thing.
I had the same issue with Label when I did "de.matthiasmann.twl.Label localLabel25 = new de.matthiasmann.twl.Label[...]" with and without the full package path.
I would also like to know if injecting something like
localLabel25.setText(localLabel25.getText().append(\" peanuts\"));
would work.
Thanks for your help.
