    <p>Essentially, you're going to need to supply a "renderer" for the tab. Take a look at <a href="http://docs.oracle.com/javase/6/docs/api/javax/swing/JTabbedPane.html#setTabComponentAt%28int,%20java.awt.Component%29" rel="noreferrer">JTabbedPane.setTabComponentAt(...)</a> for more information.</p> <p>The basic idea is to supply a component that will be laid out on the tab.</p> <p>I typically create a JPanel, onto which I add a JLabel (for the title) and, depending on what I want to display, some kind of control that acts as the close action.</p> <pre><code>tabPane.addTab(title, tabBody); int index = tabPane.indexOfTab(title); JPanel pnlTab = new JPanel(new GridBagLayout()); pnlTab.setOpaque(false); JLabel lblTitle = new JLabel(title); JButton btnClose = new JButton("x"); GridBagConstraints gbc = new GridBagConstraints(); gbc.gridx = 0; gbc.gridy = 0; gbc.weightx = 1; pnlTab.add(lblTitle, gbc); gbc.gridx++; gbc.weightx = 0; pnlTab.add(btnClose, gbc); tabPane.setTabComponentAt(index, pnlTab); btnClose.addActionListener(myCloseActionHandler); </code></pre> <p>Now somewhere else, I establish the action handler...</p> <pre><code>public class MyCloseActionHandler implements ActionListener { public void actionPerformed(ActionEvent evt) { Component selected = tabPane.getSelectedComponent(); if (selected != null) { tabPane.remove(selected); // It would probably be worthwhile getting the source // casting it back to a JButton and removing // the action handler reference ;) } } } </code></pre> <p>Now, you just as easily use any component you like and attach a mouse listener to it and monitor the mouse clicks...</p> <p><strong>Updated</strong></p> <p>The above example will only remove the currently active tab, there are a couple of ways to fix this.</p> <p>The best is to probably provide some means for the action to find the tab it's associated with...</p> <pre><code>public class MyCloseActionHandler implements ActionListener { private String tabName; public MyCloseActionHandler(String tabName) { this.tabName = tabName; } public String getTabName() { return tabName; } public void actionPerformed(ActionEvent evt) { int index = tabPane.indexOfTab(getTabName()); if (index &gt;= 0) { tabPane.removeTabAt(index); // It would probably be worthwhile getting the source // casting it back to a JButton and removing // the action handler reference ;) } } } </code></pre> <p>This uses the name of tab (as used with <code>JTabbedPane#addTab</code>) to find and then remove the tab and its associated component...</p>

    3. COThat's try. If you read the code, the ActionListener is using the selected tab. You associate the tab component with the action listener, find the index and remove it instead

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.
