Question

How can i do this? Now I will try using 2 ChangeListener and 2 ActionListeners, but this will not work. When I click the button, the checkbox from MenuItem should be checked ...

Answer 1

• a common element is a common action
• the associated property is the value for SELECTED_KEY

in code, something like

Action action = new AbstractAction("shared toggle") { @Override public void actionPerformed(ActionEvent e) { LOG.info("pressed"); } }; action.putValue(Action.SELECTED_KEY, Boolean.TRUE); JPopupMenu menu = new JPopupMenu(); menu.add(new JCheckBoxMenuItem(action)); JComponent box = new JPanel(); box.setComponentPopupMenu(menu); box.add(new JToggleButton(action)); box.add(new JCheckBox(action));

You may have the same ButtonModel . setModel and getModel defined in AbstractButton .
