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.
Does anyone have any tips?
Here is my code. I believe my issue is fine turning the size of the thumb under the getThumbSize override.
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()
}
}
