JSlider Set knob Color

Show all headers | View raw

  To: comp.lang.java.gui
Hi,

     I would like to change the JSlider's knob color. I saw an  example
on the web that used the BasicSliderUI to do that, but it doesn't work
well. When I use that it paints correctly the Slider but the rest of
the window components are not painted.
    You can see the code I am using below:



slider= new JSlider(JSlider.VERTICAL);
slider.setUI(new coloredThumbSliderUI(slider,new
Color(0x1b,0x70,0xe1)));

	public class coloredThumbSliderUI extends BasicSliderUI{

	    Color thumbColor;
	    coloredThumbSliderUI(JSlider s, Color tColor) {
	        super(s);
	        thumbColor=tColor;
	    }

		public void paint( Graphics g, JComponent c ) {
	        recalculateIfInsetsChanged();
	        recalculateIfOrientationChanged();
	        Rectangle clip = g.getClipBounds();

	        if ( slider.getPaintTrack() && clip.intersects( trackRect ) )
{
	            paintTrack( g );
	        }
	        if ( slider.getPaintTicks() && clip.intersects( tickRect ) ) {
	            paintTicks( g );
	        }
	        if ( slider.getPaintLabels() && clip.intersects( labelRect ) )
{
	            paintLabels( g );
	        }
	        if ( slider.hasFocus() && clip.intersects( focusRect ) ) {
	            paintFocus( g );
	        }
	        if ( clip.intersects( thumbRect ) ) {
	            Color savedColor = slider.getBackground();
	            slider.setBackground(thumbColor);
	            paintThumb( g );
	            slider.setBackground(savedColor);
	        }
	    }
	}

Please if anyone has an idea of what is the problem please let me
know...I am using java 1.5_07

Thanks in advance,

                          Carlos Leitao
