[SOLVED] Custom Cursors: Thick Lines

[Paul Richards]

I wanted to create my own custom cursor so I wrote some code to create a BufferedImage then I use this to create a cursor. I wanted to avoid having an image file because this is something I then have to distribute with my software.

The code below creates this cursor, it works, and also draws a rectangle by comparison.

My problem is that the lines in the cursor are incredibly thick. Is there any way around this? I'd like them to be thinner.

public class Main {
    public static Cursor GetMyCursor() {
        Image image = GetMyImage();
        Point hotSpot = new Point(0,0);
        return Toolkit.getDefaultToolkit().createCustomCursor(image, hotSpot, "my cursor");
    }

    public static Image GetMyImage() {
        int width = 10;
        int height = 10;
        BufferedImage image = new BufferedImage(width,height, BufferedImage.TYPE_4BYTE_ABGR);
        Graphics2D graphics = image.createGraphics();
        graphics.setColor(Color.BLACK);
        graphics.drawLine(0, 0, 0, 6);
        graphics.drawLine(0, 0, 6, 0);
        graphics.drawLine(3, 2, 3, 4);
        graphics.drawLine(2, 3, 4, 3);

        return image;
    }
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        JFrame test = new JFrame();
        test.add(new MyFrame());
        test.setPreferredSize(new Dimension(200,200));
        test.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
        test.pack();
        test.setCursor(GetMyCursor());
        test.setVisible(true);
    }

    public static class MyFrame extends JPanel {
        protected @Override void paintComponent(Graphics g) {
            g.drawRect(10,10,20,20);
        }
    }

}

Graphics2D.setStroke() should sort it.

The stroke may not help here as your image is being magnified more than two fold. I think the problem is that your image size is less then half the size of a cursor, and so Swing has to magnify the image to get it to fit a cursor's size. Instead, try this:

  public static Image GetMyImage()
  {
    int width = 32;
    int height = 32;

and I'll bet things will work better.

Ah, good spot

Fubarable was correct, thank you.
