setDefaultLightWeightPopupEnabled(false) doesnt work for nested JMenu's (JDK1.2)

Name: dbT83986 Date: 01/06/99


In JDK 1.2, setDefaultLightWeightPopupEnabled(false) does not
force nested JMenu's to heavy weight as it should. However
this works correctly in JDK1.1.7a (Swing 1.0.3 also known as
JFC 1.1). You can see this in the following example, try to
pick a "Steak" from the "Heavy Menu":

/*
 * This code based on from Amy Fowler's example. It adds
 * Nested JMenu's, which can not be seen under JDK 1.2 (bug) but work fine in JDK 1.1.7a

        menu.add(submenu);
        menu.add("Gravy");
        menu.add("Banana Split");
        menubar.add(menu);
        
        // Create Heavyweight AWT Button
        Button heavy = new Button(" Heavyweight Button ");
        
        // Add heavy button to box
        Box box = Box.createVerticalBox();
        box.add(Box.createVerticalStrut(20));
        box.add(heavy);
        box.add(Box.createVerticalStrut(20));
        getContentPane().add("Center", box);
        pack();
     }

     public static void main(String[] args) {
         MixPopupTest t = new MixPopupTest();
         t.setSize(400,200);
         t.show();
     }
 }

// Resize the JFrame so it is very small, and the missing "Steak"
// JMenu becomes heavy weight.
