RE: Separator in Combo box

[Farwell, Paul]

We got this functionality by stuffing a JSeparator into the combo model where the separator should appear and then overriding BasicComboBoxRenderer to return a specialized renderer.   Here is the implementation of our BasicComboBoxRenderer:       /**     * Override super.getListCellRendererComponent()     */    public Component getListCellRendererComponent(JList list,              Object value,              int index,              boolean isSelected,              boolean cellHasFocus) {         // ...       Component renderer = super.getListCellRendererComponent(                                        list,                                        value,                                        index,                                        isSelected,                                        cellHasFocus);       // other logic here....         // create a specialized renderer is the model value is a JSeparator....       if (value instanceof JSeparator) {          renderer = getSeparator();       }         return renderer;    }      /**     * Creates a list separator.     */    private JPanel getSeparator() {       if (_sepPanel != null)          return _sepPanel;         // we put the separator inside a panel to control       // its appearance       _sepPanel = new JPanel();       Border sepBorder = BorderFactory.createEmptyBorder(1, 3, 1, 3);       _sepPanel.setOpaque(false);       _sepPanel.setBorder(sepBorder);       _sepPanel.setLayout(new BoxLayout(_sepPanel, BoxLayout.Y_AXIS));       _sepPanel.add(Box.createRigidArea(new Dimension(0, 4)));       _sepPanel.add(new JPopupMenu.Separator());       _sepPanel.add(Box.createRigidArea(new Dimension(0, 4)));       return _sepPanel;    }         You also want to create a subclass of JComboBox, overriding setSelectedIndex and setSelectedItem so that these methods skip selection of the JSeparator in the combo list. -----Original Message----- From: Lim Ting [mailto:[EMAIL PROTECTED]] Sent: Friday, July 20, 2001 10:37 PM To: [EMAIL PROTECTED] Subject: Separator in Combo box Does anyone know how to create a separator in a combo box, something similar like menu separator?   Lim Ting
