    <p>This is a known bug: <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4737788" rel="noreferrer">http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4737788</a></p> <p>Quote from this link:</p> <blockquote> <p>A workaround is to subclass JFrame and override the setExtendedState method, catching any maximize events before they happen and setting the maximum bounds of the frame appropriately before calling the superclass's setExtendedState method.</p> </blockquote> <pre><code>import java.awt.*; import javax.swing.*; public class PFrame extends JFrame { private Rectangle maxBounds; public PFrame() { super(); maxBounds = null; } //Full implementation has other JFrame constructors public Rectangle getMaximizedBounds() { return(maxBounds); } public synchronized void setMaximizedBounds(Rectangle maxBounds) { this.maxBounds = maxBounds; super.setMaximizedBounds(maxBounds); } public synchronized void setExtendedState(int state) { if (maxBounds == null &amp;&amp; (state &amp; Frame.MAXIMIZED_BOTH) == Frame.MAXIMIZED_BOTH) { Insets screenInsets = getToolkit().getScreenInsets(getGraphicsConfiguration()); Rectangle screenSize = getGraphicsConfiguration().getBounds(); Rectangle maxBounds = new Rectangle(screenInsets.left + screenSize.x, screenInsets.top + screenSize.y, screenSize.x + screenSize.width - screenInsets.right - screenInsets.left, screenSize.y + screenSize.height - screenInsets.bottom - screenInsets.top); super.setMaximizedBounds(maxBounds); } super.setExtendedState(state); } } </code></pre>

    2. COBecause maximising the frame could be called from two different threads. If one thread sets the maxBounds field while another thread is in the middle of the setExtendedState method (for example), you will have strange results...

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).
