I`ve customized an jSlider facing a little problem-
After changing values, on my custom jSlider is a border shown. Sorry, I´ve made pictures but Iàm not allowed to post it. The not customized jSlider do not show such border after click on it.
Is there an Method i have to Override to get rid of this border? Thank you in advance!
Sorry for my english! Hope anyone can help me! This is my Customized UI:
public class RedGreenSliderUI extends BasicSliderUI{
Image knobImage ;
private BasicStroke stroke = new BasicStroke(1f, BasicStroke.CAP_ROUND,
BasicStroke.JOIN_ROUND, 0f, new float[]{1f, 2f}, 0f);
private static final float[] fractions = {0.0f, 0.5f};
private static final Color[] fillColors = {
/* new Color(0x2687AE),*/
/* new Color(0x1658AE)*/
new Color(0xc8041b),
new Color(0xc8041b)
};
private static final Color[] backColors = {
new Color(0x04c814),
new Color(0x04c814)
};
private static final Paint hFillGradient = new LinearGradientPaint(0, 0, 0, 11,
fractions, fillColors, MultipleGradientPaint.CycleMethod.NO_CYCLE);
private static final Paint hBackGradient = new LinearGradientPaint(0, 0, 0, 11,
fractions, backColors, MultipleGradientPaint.CycleMethod.NO_CYCLE);
private static final Paint vFillGradient = new LinearGradientPaint(0, 0, 11, 0,
fractions, fillColors, MultipleGradientPaint.CycleMethod.NO_CYCLE);
private static final Paint vBackGradient = new LinearGradientPaint(0, 0, 11, 0,
fractions, backColors, MultipleGradientPaint.CycleMethod.NO_CYCLE);
private static final Stroke roundEndStroke = new BasicStroke(5,
BasicStroke.CAP_BUTT, BasicStroke.JOIN_ROUND);
public RedGreenSliderUI( JSlider aSlider ) {
super( aSlider );
try {
this.knobImage = ImageIO.read(getClass().getResource("ringelblumensalbe- Updater-Grafiken/tongThumb01.png")); //.getClassLoader()
} catch ( IOException e ) {
e.printStackTrace();
}
}
public void paintThumb(Graphics g) {
g.drawImage( this.knobImage, thumbRect.x, thumbRect.y, 15, 30, null );
}
@Override
protected Dimension getThumbSize() {
return new Dimension(15, 30);
}
@Override
protected Color getHighlightColor() {
return new Color(98, 94, 0);
}
public void paintTrack(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
if (slider.getOrientation() == JSlider.HORIZONTAL) {
int cy = (trackRect.height / 2) - 2;
g.translate(trackRect.x, trackRect.y + cy);
g2.setStroke(roundEndStroke);
g2.setPaint(hBackGradient);
g2.drawLine(thumbRect.x, 2, trackRect.width, 2);
g2.setPaint(hFillGradient);
g2.drawLine(0, 2, thumbRect.x, 2);
g.translate(-trackRect.x, -(trackRect.y + cy));
} else {
int cx = (trackRect.width / 2) - 2;
g.translate(trackRect.x + cx, trackRect.y);
g2.setStroke(roundEndStroke);
g2.setPaint(vBackGradient);
g2.drawLine(2, 0, 2, thumbRect.y);
g2.setPaint(vFillGradient);
g2.drawLine(2, thumbRect.y, 2, trackRect.height);
g.translate(-(trackRect.x + cx), -trackRect.y);
}
}
EDIT: I`ve got it. The answer is to override getFocusColor().
@Override
protected Color getFocusColor(){
return new Color(255,255,255);
}
You can try using border:0px; property for particular class where border is shown.
