    <p>The problem is that you set tooltips on subcomponents of the component returned by your CellRenderer. To perform what you want, you should consider override <code>getToolTipText(MouseEvent e)</code> on the JTable. From the event, you can find on which row and column the mouse is, using:</p> <pre><code>java.awt.Point p = e.getPoint(); int rowIndex = rowAtPoint(p); int colIndex = columnAtPoint(p); </code></pre> <p>From there you could then re-prepare the cell renderer, find which component is located at the mouse position and eventually retrieve its tooltip.</p> <p>Here is a snippet of how you could override JTable getToolTipText:</p> <pre><code>@Override public String getToolTipText(MouseEvent event) { String tip = null; Point p = event.getPoint(); // Locate the renderer under the event location int hitColumnIndex = columnAtPoint(p); int hitRowIndex = rowAtPoint(p); if (hitColumnIndex != -1 &amp;&amp; hitRowIndex != -1) { TableCellRenderer renderer = getCellRenderer(hitRowIndex, hitColumnIndex); Component component = prepareRenderer(renderer, hitRowIndex, hitColumnIndex); Rectangle cellRect = getCellRect(hitRowIndex, hitColumnIndex, false); component.setBounds(cellRect); component.validate(); component.doLayout(); p.translate(-cellRect.x, -cellRect.y); Component comp = component.getComponentAt(p); if (comp instanceof JComponent) { return ((JComponent) comp).getToolTipText(); } } // No tip from the renderer get our own tip if (tip == null) { tip = getToolTipText(); } return tip; } </code></pre>

    1. COThank you for your reply. If I set the tooltip to JPanel in my code its working properly. But the requirement here is to display tooltips for each JLabel inside JPanel (JPanel is added to one particular column in the JTable).

    3. CO@user1430989 I posted a version of JTable.getToolTipText that should work on your code.

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.

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