    <p>You can draw to the BufferedImage like this:</p> <pre><code>public BufferedImage createSkelethonizationImage() { BufferedImage image = new BufferedImage(width, height); Graphics2D g2 = image.createGraphics(); // Perform your drawing here g2.drawLine(...); g2.dispose(); return image; } </code></pre> <p>To draw the image, create a new class that extends JComponent and overrides the paint method. Here is some code to get started:</p> <pre><code>public class MyImage extends JComponent { // Note: the image should be modified on the Event Dispatch Thread private BufferedImage image = createSkelethonizationImage(); @Override public void paint(Graphics g) { g.drawImage(image, 0, 0, this); } } </code></pre> <p>Edit - Complete solution:</p> <pre><code>public class Test { public static void main(String[] args) { // Width and height of your image final int width = 200; final int height = 200; SwingUtilities.invokeLater(new Runnable() { @Override public void run() { JFrame frame = new JFrame(); MyImage image = new MyImage(width, height); frame.add(image); frame.setSize(new Dimension(width, height)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } }); } } class MyImage extends JComponent { // Note: image should be modified on the Event Dispatch Thread only private final BufferedImage image; public MyImage(int width, int height) { image = createSkelethonizationImage(width, height); setPreferredSize(new Dimension(width, height)); } public BufferedImage createSkelethonizationImage(int width, int height) { BufferedImage iamge = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB); Graphics2D g2 = iamge.createGraphics(); // Perform your drawing here g2.setColor(Color.BLACK); g2.drawLine(0, 0, 200, 200); g2.dispose(); return iamge; } @Override public void paint(Graphics g) { g.drawImage(image, 0, 0, this); } } </code></pre>

    1. COOk, but how can I create the Skelethonization effect? I'm looking for something to start with, to obtain that effect...

    2. COYou will need to either find and use a library or implement the algorithm yourself. You might be able to use the source code from the [AnalyzeSkeleton](http://imagejdocu.tudor.lu/doku.php?id=plugin:analysis:analyzeskeleton:start) project. (Note: the Jar download link is broken, but the source code exists on their git site.)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
