    <p>Indeed it does not update itself, even when resetting the tooltip to null between calls.</p> <p>So far, the only trick I found was to simulate a mouse-move event and forward it on the TooltipManager. It makes him think that the mouse has moved and that the tooltip must be relocated. Not pretty, but quite efficient.</p> <p>Have a look at this demo code which displays a progress in % from 0 to 100:</p> <pre><code>import java.awt.MouseInfo; import java.awt.Point; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseEvent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingUtilities; import javax.swing.Timer; import javax.swing.ToolTipManager; public class TestTooltips { protected static void initUI() { JFrame frame = new JFrame("test"); final JLabel label = new JLabel("Label text"); frame.add(label); frame.pack(); frame.setVisible(true); Timer t = new Timer(1000, new ActionListener() { int progress = 0; @Override public void actionPerformed(ActionEvent e) { if (progress &gt; 100) { progress = 0; } label.setToolTipText("Progress: " + progress + " %"); Point locationOnScreen = MouseInfo.getPointerInfo().getLocation(); Point locationOnComponent = new Point(locationOnScreen); SwingUtilities.convertPointFromScreen(locationOnComponent, label); if (label.contains(locationOnComponent)) { ToolTipManager.sharedInstance().mouseMoved( new MouseEvent(label, -1, System.currentTimeMillis(), 0, locationOnComponent.x, locationOnComponent.y, locationOnScreen.x, locationOnScreen.y, 0, false, 0)); } progress++; } }); t.start(); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { initUI(); } }); } } </code></pre>

    1. COJust one minor problem. The initial delay of the tooltip has to be < to the update delay of the text.

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.
