    <p>I think The <code>repaint()</code> in your <code>paintComponent()</code> code causes an endless recursion.</p> <p>repaint --> paintComponent --> repaint -->...</p> <p>This is messing up the Graphics object.</p> <p><strong>edit:</strong></p> <p>There is another error in your code, your calling super.paintComponent <strong>s</strong> (g) instead of <code>super.paintComponent(g)</code>. Try to use the method without the <strong>s</strong>.</p> <p>Here is a simple example of a class that moves the string according to the position of the last click:</p> <hr> <pre class="lang-java prettyprint-override"> public class Test extends JPanel implements MouseListener { private int x = 100; private int y = 100; public static void main(String[] args) { JFrame jFrame = new JFrame(); Test test = new Test(); jFrame.add(test); jFrame.setBounds(0, 0, 800, 600); jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); jFrame.setVisible(true); jFrame.addMouseListener(test); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); g.drawString("blub", x, y); } @Override public void mouseClicked(MouseEvent e) { this.x = e.getX(); this.y = e.getY(); repaint(); } @Override public void mousePressed(MouseEvent e) { } @Override public void mouseReleased(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseEntered(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseExited(MouseEvent e) { // TODO Auto-generated method stub } } </pre>

    2. COEven after removing the repaint() method at the paintcomponent(Graphics g) it still does not slove the problem but at the actionlistener code section it does not move the object

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).
