    <p>your code works for me, but working only on mouse wheel event, you have to scroll with mouse wheel</p> <p>modified example </p> <pre><code>import java.awt.*; import java.awt.event.MouseWheelEvent; import java.awt.event.MouseWheelListener; import javax.swing.*; public class Test extends JFrame implements MouseWheelListener { private static final long serialVersionUID = 1L; private JPanel p; public Test() { setLayout(new FlowLayout()); setPreferredSize(new Dimension(1000, 1000)); setDefaultCloseOperation(EXIT_ON_CLOSE); p = new JPanel(); p.setPreferredSize(new Dimension(200, 200)); p.setBackground(Color.red); add(p); addMouseWheelListener(this); pack(); setVisible(true); } public void mouseWheelMoved(MouseWheelEvent e) { Dimension dim100 = new Dimension(100, 100); Dimension dim200 = new Dimension(200, 200); System.out.println(p.getSize()); if (p.getPreferredSize().equals(dim100)) { p.setPreferredSize(dim200); p.revalidate(); System.out.println(p.getSize()); } else if (p.getPreferredSize().equals(dim200)) { p.setPreferredSize(dim100); p.revalidate(); System.out.println(p.getSize()); } } public static void main(String args[]) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new Test(); } }); } } </code></pre> <p>EDIT:</p> <p>have to delay <code>System.out.println(p.getSize());</code>, invokeLater() is best of all in this case, becase container returned changed Dimension after all events are done in the EDT </p> <p>example</p> <pre><code>import java.awt.*; import java.awt.event.MouseWheelEvent; import java.awt.event.MouseWheelListener; import javax.swing.*; public class Test extends JFrame implements MouseWheelListener { private static final long serialVersionUID = 1L; private JPanel p; public Test() { setLayout(new FlowLayout()); setPreferredSize(new Dimension(1000, 1000)); setDefaultCloseOperation(EXIT_ON_CLOSE); p = new JPanel(); p.setPreferredSize(new Dimension(900, 900)); p.setBackground(Color.red); add(p); addMouseWheelListener(this); pack(); setVisible(true); } public void mouseWheelMoved(MouseWheelEvent e) { Dimension dim100 = p.getSize(); System.out.println("before "+ p.getSize()); p.setPreferredSize(new Dimension(dim100.height - 5, dim100.width - 5)); p.revalidate(); EventQueue.invokeLater(new Runnable() { @Override public void run() { System.out.println("after "+ p.getSize()); } }); } public static void main(String args[]) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new Test(); } }); } } </code></pre> <p>generated</p> <pre><code>before java.awt.Dimension[width=900,height=900] after java.awt.Dimension[width=895,height=895] before java.awt.Dimension[width=895,height=895] after java.awt.Dimension[width=890,height=890] before java.awt.Dimension[width=890,height=890] after java.awt.Dimension[width=885,height=885] before java.awt.Dimension[width=885,height=885] after java.awt.Dimension[width=880,height=880] before java.awt.Dimension[width=880,height=880] after java.awt.Dimension[width=875,height=875] before java.awt.Dimension[width=875,height=875] after java.awt.Dimension[width=870,height=870] before java.awt.Dimension[width=870,height=870] after java.awt.Dimension[width=865,height=865] before java.awt.Dimension[width=865,height=865] after java.awt.Dimension[width=860,height=860] </code></pre>

    1. COThanks for your reply, your code works great, you can scroll back the size :) But it was not my question, I just want to be able to get the correct size from getSize() after I scroll the wheel. Maybe I wasn't clear enough, I edited the question.

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).
