    <p>This example compiles fine. And you can see from running the it, the problem I'm facing. I want the JPanels to paint directly on the Desktop, without a visible JWindow content pane. I also need a JScrollpane to be visible in order to shift through the JPanel array horizontally!</p> <p>Appreciate any help.</p> <pre><code>/* * SSCE.java * Short Self Contained Example * * Problem: Cant make the containers scrollpane non-opaque! (ie. transparent) */ package fb; import com.sun.awt.AWTUtilities; import java.awt.Color; import java.awt.Container; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Toolkit; import javax.swing.BorderFactory; import javax.swing.JEditorPane; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JWindow; import javax.swing.ScrollPaneConstants; /** * * @author Aubrey */ public class SSCE { JWindow w = new JWindow(); Container c = w.getContentPane(); JPanel[] ps; Toolkit toolkit = Toolkit.getDefaultToolkit (); Dimension dim = toolkit.getScreenSize(); int width = dim.width; int height= dim.height; public SSCE(){ c.setLayout(new FlowLayout(FlowLayout.CENTER, 20, 5)); JScrollPane scrollPane = new JScrollPane(c); scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_NEVER); scrollPane.setOpaque(false); ps = new JPanel[19]; for(int i=0; i&lt;19; i++){ ps[i]=new JPanel(); ps[i].setLocation(0, 0); ps[i].setSize(400, 400); ps[i].setVisible(true); JEditorPane area = new JEditorPane(); area.setEditable(false); area.setOpaque(false); area.setSize(400, 400); area.setForeground(Color.WHITE); area.setText("Date: \nFrom: \n\nMessage: "+i); ps[i].add(area); ps[i].setBorder(BorderFactory.createLineBorder(Color.GRAY)); ps[i].setBackground(Color.darkGray); c.add(ps[i]); } if (AWTUtilities.isTranslucencySupported(AWTUtilities.Translucency.TRANSLUCENT)) { System.out.println("TranslucencySupported !!!!"); AWTUtilities.setWindowOpaque(w, false); }else{System.out.println("Translucency NOT Supported !!!!");} //Problem seems to be here --&gt; either the scrollPane or the Container is not non-opaque (ie. transparent)!

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.
