    <p>So this is my code:</p> <pre><code>public class DesktopFrame extends JFrame{ private JDesktopPane theDesktop; private JInternalFrame login; private JMenuBar bar; private JMenu fileMenu; private JMenuItem newLoginFrame; private LoginPanel panel; // set up GUI public DesktopFrame(){ super( "Application" ); bar = new JMenuBar(); // create menu bar bar.setBackground(new Color(255,215,0)); fileMenu = new JMenu( "File" ); // create Add menu fileMenu.setBackground(new Color(255,215,0)); newLoginFrame = new JMenuItem( "Login" ); newLoginFrame.setBackground(new Color(255,215,0)); fileMenu.add( newLoginFrame ); // add new frame item to Add menu bar.add(fileMenu); // add Add menu to menu bar setJMenuBar(bar); // set menu bar for this application theDesktop = new JDesktopPane(); // create desktop pane theDesktop.setBackground(Color.BLUE); add(theDesktop); // add desktop pane to frame // set up listener for newLoginFrame menu item newLoginFrame.addActionListener(new ActionListener(){ // anonymous inner class // display new internal window public void actionPerformed( ActionEvent event ){ login = new JInternalFrame("Member Login", false, false, false, false); panel = new LoginPanel(); login.add( panel, BorderLayout.CENTER ); // add panel login.setSize(375,300); login.setLocation(20,20); theDesktop.add( login ); // attach internal frame login.setVisible( true ); // show internal frame } // end method actionPerformed } // end anonymous inner class); // end call to addActionListener } // end DesktopFrame constructor public void getValid(){ if(panel.getValid() == true){ try{ login.setClosed(true); } catch(PropertyVetoException p){ } } } } // end class DesktopFrame </code></pre> <p>In this document, there is also another class "LoginPanel" which handles all of the login frame. If the username/password work, it creates a boolean variable "valid" that is true. I have called it with "panel.getValid()". As you can see the purpose is to exit the login frame when "valid" is true. Is this possible? What do people recommend? Right now, with the "setClosed" it is exiting the entire frame, not just the inner "Login" frame. I don't know why</p>

    1. CO1) Don't extend frame or other top level containers. Instead create & use an instance of one. 2) Use a consistent and logical indent for code blocks. The indentation of the code is intended to help people understand the program flow. 3) For better help sooner, post an [SSCCE](http://sscce.org/).

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.
