    <p>I need to display multiple images so that users may compare them and I'm not sure what method to use. I have an app that allows the user to choose image files so I have a File Object. I've tried to generate new GUIs with "new" but that doesn't work well.</p> <p>Should I code a standalone app (with a main) and use a system call to start them with a new JVM? I'm new at Java and have just touched the surface of AWT and SWING. </p> <p>The class is called thus where name is an arbitrary unique String:</p> <pre><code>ImageWindowStub iw = new ImageWindowStub(name); </code></pre> <p>Here is simple code that demonstrates the problem if called in succession.</p> <pre><code>package fireScience.airborne.image; import java.awt.Dimension; import javax.swing.BoxLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.SwingConstants; import javax.swing.SwingUtilities; import javax.swing.border.BevelBorder; public class ImageWindowStub { private static JFrame frame; private static JPanel statusPanel; private static JLabel statPixInfoLbl; private static String theString; public ImageWindowStub(String theString) { this.theString = theString; statusPanel = new JPanel(); createAndShowGui(); } private static void createAndShowGui() { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { frame = new JFrame(theString); JFrame.setDefaultLookAndFeelDecorated(true); frame.setResizable(true); frame.setSize(300, 200); frame.setLocation(50, 50); statusPanel = new JPanel(); statusPanel.setBorder(new BevelBorder(BevelBorder.LOWERED)); statusPanel.setPreferredSize(new Dimension(frame.getWidth(), 24)); statusPanel.setLayout(new BoxLayout(statusPanel, BoxLayout.X_AXIS)); statPixInfoLbl = new JLabel("Status Bar"); statPixInfoLbl.setHorizontalAlignment(SwingConstants.LEFT); statusPanel.add(statPixInfoLbl); frame.add(statusPanel); frame.pack(); frame.setVisible(true); } }); } } </code></pre> <p>My core question is "What is the best way to generate multiple independent instances of a GUI class?"</p>

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.
