JButton – Events


Action Fired

jButton1.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent evt) {
        System.out.println("Action Command: " + evt.getActionCommand());
        System.out.println("Modifier Keys");
        System.out.println("    SHIFT: " + ((evt.getModifiers()& ActionEvent.SHIFT_MASK)>0));
        System.out.println("     CTRL: " + ((evt.getModifiers()& ActionEvent.CTRL_MASK)>0));
        System.out.println("     META: " + ((evt.getModifiers()& ActionEvent.META_MASK)>0));
        System.out.println("      ALT: " + ((evt.getModifiers()& ActionEvent.ALT_MASK)>0));
        System.out.println("Timestamp of when this occured: " + (new Date(evt.getWhen())));
    }
});

Change Listener

jButton1.addChangeListener(new ChangeListener() {
    @Override
    public void stateChanged(ChangeEvent evt) {
        System.out.println("Source (hash): " + evt.getSource().getClass().getSimpleName() + "(" + evt.getSource().hashCode() + ")");
    }
});

Item Listener

jButton1.addItemListener(new ItemListener() {
    @Override
    public void itemStateChanged(ItemEvent evt) {
        System.out.println("Item: " + evt.getPropertyName());
        
        String stateString = "unknown";
        if(state == ItemEvent.SELECTED){
            stateString = "SELECTED";
        }else if(state == ItemEvent.DESELECTED){
            stateString = "DESELECTED";
        }
        
        System.out.println("State Change: " + stateString);
    }
});
