Hi,

I do not get the problem you've got. All components seem to paint
correctly, so the problem you've got could be in another area of your
code.

Besides that, it's possible to change the color of the knob by simply
overriding some UIDefaults values. You could do the following:

    java.util.List sliderGradient =3D Arrays.asList(new Object[] {
        new Float(.3f),
        new Float(.3f),
        new ColorUIResource(0xC8DDF2),
        new Color(0x1b, 0x70, 0xe1),
        new ColorUIResource( 0x2b, 0x80, 0xF1 )
    });

    UIManager.getDefaults().put("Slider.gradient", sliderGradient);
    UIManager.getDefaults().put("Slider.focusGradient",
sliderGradient);

This way you don't have to implement your own UI.

Note that this will work for the MetalLookAndFeel. Other L&F's might
require other settings to change it.=20

Regards,

Bart
