    <p>i have a popup menu (that comes out when the user uses right click on specified elements), wich items are readed from a list. I want that when an item is selected, that item is disabled in the popupMenu (then if some action happen it will return enabled). I have implemented the popupMenu, but i cannot implement this enable/disable JMenuItem element. Anyone can help me? Thanks</p> <pre><code> class PopupTriggerListener extends MouseAdapter { public void mousePressed(MouseEvent ev) { if (ev.isPopupTrigger()) { menu.show(ev.getComponent(), ev.getX(), ev.getY()); x = ev.getX(); y = ev.getY(); } } public void mouseReleased(MouseEvent ev) { if (ev.isPopupTrigger()) { menu.show(ev.getComponent(), ev.getX(), ev.getY()); x = ev.getX(); y = ev.getY(); } } public void mouseClicked(MouseEvent ev) { } } } JLabel label = new MyLabel("right-click"); public Test() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JMenuItem item = new JMenuItem("Test1"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("Menu item Test1"); JLabel newLabel = new JLabel("test"); label.add(newLabel); newLabel.setBounds(x, y, 40, 10); } }); menu.add(item); item = new JMenuItem("Test2"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("Menu item Test2"); } }); menu.add(item); getContentPane().add(label); pack(); setSize(300, 100); } public static void main(String[] args) { new Test().setVisible(true); } </code></pre>

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.
