    Hello

    this is also a program for beginners that draws a "Hello world" in the screen :-

    import waba.ui.*;
    import waba.fx.*;
     
    public class HelloWorld extends MainWindow
    {
    public void onPaint(Graphics g)
      {
      g.setColor(0, 0, 0);
      g.drawText("Hello World", 0, 0);
      }
    }

    Please note you cannot do this unless you have the waba framework & wabaJDK installed on your machine.

    EDIT: Thanks JavaPF

    This is a much better example Truffy. Thanks. The code posted by shikh_albelad requires non standard imports.
