    <p>The picture explains it all. I've painted a new Thumb and it goes off the JSlider area when at higher than 95 or below 5. I've tried padding the Track with no success.</p> <p><img src="https://dl.dropbox.com/u/2363305/Forums/Java/JSlider_Thumb_OffScreen.png" alt="alt text"></p> <p>Does anyone have any tips?</p> <p>Here is my code. I believe my issue is fine turning the size of the thumb under the getThumbSize override.</p> <pre><code>private static class MySliderUI extends BasicSliderUI { private int thumbHeight = 22; private int thumbWidth = 22; public MySliderUI(JSlider b) { super(b); // this.thumbHeight = slider.getHeight(); // this.thumbWidth = slider.getHeight(); } @Override protected Dimension getThumbSize() { return new Dimension(thumbHeight, thumbWidth); } @Override public void paintTrack(Graphics g) { Graphics2D g2d = (Graphics2D) g; Rectangle r = trackRect; r.width = 40; // (int) (0.15 * r.getHeight()); float[] dist = { 0.1f, 0.5f, 0.9f }; Color[] colors = { new Color(34, 177, 76), new Color(255, 242, 0), new Color(237, 28, 36) }; Point2D start = new Point2D.Float(r.x, r.y); Point2D end = new Point2D.Float(r.x, r.y + r.height); LinearGradientPaint p = new LinearGradientPaint(start, end, dist, colors); g2d.setPaint(p); g2d.fill(r); } @Override public void paintThumb(Graphics g) { Graphics2D g1 = (Graphics2D) g; // Make a triangle - Arrow on Meter int[] x = new int[3]; int[] y = new int[3]; int n; // count of points // Set Points for Arrow Integer arrowX = thumbRect.x; Integer arrowY = thumbRect.y; x[0] = arrowX - 25; x[1] = arrowX - 25; x[2] = arrowX - 2; y[0] = arrowY - 17; // Top Left y[1] = arrowY + 27; // Bottom Left y[2] = arrowY + 5; // Tip of Arrow n = 3; // Number of points, 3 because its a triangle // Draw Arrow Border Polygon myTriShadow = new Polygon(x, y, n); // a triangle g1.setPaint(Color.black); g1.fill(myTriShadow); // Set Points for Arrow Board x[0] = x[0] + 2; x[1] = x[1] + 2; x[2] = x[2] - 3; y[0] = y[0] + 5; y[1] = y[1] - 5; y[2] = y[2]; // Color colorMeter = robot.getPixelColor(x[2]+10, y[2]); // Draw Arrow Polygon myTri = new Polygon(x, y, n); // a triangle // Color colr = new Color(); g1.setPaint(Color.yellow); g1.fill(myTri); // super.paintThumb(g); // replace with your fill() } } </code></pre>

    1. COYet again you asked a question we can't help you with (I see you deleted the last one). You have written custom code and you obviously have a bug in the code. What do you expect us to do about it since you haven't posted a SSCCE (http://sscce.org)? We don't know what you have changed. If you post a SSCCE that shows the old code and highlights what you have changed, then maybe someone will be generous enought to look at the code. Otherwise we are not mind readers and can't guess what you have done.

    2. COI thank you for your help, but it seems that others are able to "Read my mind" and post information and push me in a direction to help me.

    3. CO@Landmine: As a fan of the http://sscce.org/, I would not discount camickr's suggestion too quickly. Just creating one offers considerable insight and occasionally reveals an immediate solution. Very nice gradient, BTW.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
