      Description

      (The description field of this report went missing when I first submitted it.)

      Compile and run the following program:

      --------
      import java.applet.*;
      import java.awt.*;

      public class test extends Applet
      {
         public static void main(String args[])
         {
            Frame f = new Frame("Test");
            test t = new test();

            t.init();
            t.start();

            f.resize(100, 100);
            f.add("Center", t);
            f.show();
         }

         public void init()
         {
            setLayout(new BorderLayout());
            add("Center", new Test());
         }
      }

      class Test extends Panel
      {
         Checkbox box = new Checkbox("i am happy");
         
         public Test()
         {
            setLayout(new BorderLayout());
            add("Center", box);
         }

         public boolean action(Event evt, Object obj)
         {
            if (evt.target instanceof Checkbox)
            {
      Checkbox box = (Checkbox) evt.target;

      if (box.getState())
      {
      box.setLabel("happy i am");
      } else {
      box.setLabel("sad = 1");
      }
            }
            return true;
         }
      }
      --------

      When the checkbox is pressed, X (probably Motif) complains with:

      Warning:
          Name: i am happy
          Class: XmToggleButton
          Invalid XmNlabelString - must be a compound string

      The description field as copied from bug report 1234619 follows:


      When a checkbox is added to an applet and then its label is changed using setLabel()
      it generates a warning (and infact the label remains unchanged).

      Here is the result of executing CheckboxTest2.java from the AWT test suite.

      [284] [awt] ? appletviewer CheckboxTest2.html
      thread applet-CheckboxTest2.class find class CheckboxTest2
      Opening stream to: file:/home/vijay/jdk-ws/src/share/test/awt/CheckboxTest2.class to get CheckboxTest2
      Warning:
          Name: WrongLabel1
          Class: XmToggleButton
          Invalid XmNlabelString - must be a compound string

      Warning:
          Name: WrongLabel1
          Class: XmToggleButton
          Invalid XmNlabelString - must be a compound string
      ^C

      However if the buttons are added to a panel which is then added to the applet,
      and then its label is changed, the motif warning doesnt appear and the label change
      works fine.
