    <p>Hi, I am making a program that has a <code>JSplitPane</code> and its background is transparent so I add two panels with a <code>JScrollPane</code> on the <code>JSplitPane</code>.. when I add the contents in the panel it doesn't appear.</p> <p>This is the code that I was using:</p> <pre><code>import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JSplitPane; import javax.swing.JViewport; import javax.swing.UIManager; public class sample { JFrame mainFrame; JPanel mainPanel; JPanel splitPaneLeftPanel; JPanel splitPaneRightPanel; JSplitPane splitPane; JScrollPane rightPanelScroll; JScrollPane leftPanelScroll; JViewport viewport; sample(){ Frame(); SplitPaneAndContent(); mainFrame.setVisible(true); } public void Frame(){ mainFrame = new JFrame(); mainFrame.setTitle("Sample"); mainFrame.setLayout(new BorderLayout()); mainFrame.setSize(1024,720); mainFrame.setMaximumSize(new Dimension(1366,768)); mainFrame.setMinimumSize(new Dimension(800,600)); mainFrame.setResizable(true); mainFrame.setLocationRelativeTo(null); mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public void SplitPaneAndContent(){ mainPanel = new JPanel(new BorderLayout()); splitPaneLeftPanel = new JPanel(new BorderLayout()); splitPaneRightPanel = new JPanel(new BorderLayout()); mainPanel.setBackground(Color.blue); JScrollPane rightPanelScroll = new JScrollPane(splitPaneRightPanel); JScrollPane LeftPanelScroll = new JScrollPane(splitPaneLeftPanel); viewport = new JViewport(); rightPanelScroll.setViewport(viewport); rightPanelScroll.getViewport().setOpaque(false); JLabel Text = new JLabel("SAMPLE"); Text.setBackground(Color.red); splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,LeftPanelScroll,rightPanelScroll); splitPane.setDividerLocation(300); splitPaneLeftPanel.setOpaque(false); splitPaneRightPanel.setOpaque(false); rightPanelScroll.setOpaque(false); splitPane.setOpaque(false); splitPaneRightPanel.add(Text, BorderLayout.CENTER); mainPanel.add(splitPane, BorderLayout.CENTER); mainFrame.add(mainPanel, BorderLayout.CENTER); } public static void main(String[] args) { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); new sample(); } catch (Exception e) { System.out.println(e); } } } </code></pre>

    1. COWhen Opaque is set to false, both the pane and its children will be hidden. That's how it works.

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.
