When I dropping the label/image into center panel.It reads -X &amp; Y Cooridnates and check the code</p> <pre><code>private void mak_lis(final SLabel l) { l.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent m) { System.out.println("mak_lis Mouse mousePressed"); setCursor(yd); // l.setBorder(new MatteBorder(1,1,1,1,Color.black)); } public void mouseReleased(MouseEvent m) { l.setBorder(null); setCursor(dc); System.out.println("mak_lis Mouse mouseReleased"); int x = -(m.getX() + l.getX() - leftPanel.getX()); int y = m.getY() + l.getY() + leftPanel.getY(); System.out.println("mak_lis Mouse mouseReleased" + "x" + x+ "y" + y); if (y &gt; 0 &amp;&amp; x &gt; 0 &amp;&amp; y &lt; leftPanel.getHeight() &amp;&amp; x &lt; leftPanel.getWidth()) { leftPanel.add(new_lab(l, x, y)); leftPanel.repaint(); Component[] components1 = leftPanel.getComponents(); Component component = null; for (int i = 0; i &lt; components1.length; i++) { // System.out.println("components iii"+ components1[i]); component = components1[i]; } } } }); } </code></pre> <p>Please tell me is there any missing here.

    1. CO*"I am implementing designer tool using swing."* A D'n'D GUI designer? (shudder) There are already too many of them creating problems that GUI programmers have to fix later.

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).
