enalbe, disable checkboxes

[Alex Teslin]

Hi,

Is there a way to enable or disable checkboxes as you can do it for JButtons , such as this:

button1.setActionCommand("disable");
button1.setEnabled(false);

Then:

actionPerformed(ActionEvent e)
if("enable".equals(e.getActionCommand())) {
button1.setEnabled(true);
}

But when i try in checkBoxes like this:

itemStateChanged(ItemEvent e) {
if("enable".equals(e.getActionCommand())){}

it gives me an error:
cannot find symbol-method getActionCommand()

Which is not surprising because in ItemEvent class there is no getActionCommand() method.

But how can i use the same functionality as for JButtons?

Thank you

This should do about the same thing.

((JCheckBox)e.getItem()).getText()

[Alex Teslin]

Which class getText() is in?

Compiler can not find it.

Thanks

Yes, but that returns the name of the JCheckBox.
How would i know if it is enabled or disabled?
Because i need to enable or disable depending on that

The ActionEvent class has a getActionCommand method. The ItemEvent class does not. However, both classes have access to their superclass (EventObject) method getSource which is used to get a reference to the component that generated the event. In the case of a class extending AbstractButton (JButton, JMenuItem and JToggleButton) there is also a getActionCommand method. JCheckBox extends from JToggleButton so it has access to the getActionCommand method of AbstractButton.
So how might this work?

JCheckBox cb = new JCheckBox("one");
cb.setActionCommand("number one");
...
public void itemStateChanged(ItemEvent e) {
    // get a reference to the JCheckBox that sent the event,
    // this cast is okay if JCheckBox is the only type of
    // Component registered with this ItemListener
    JCheckBox checkBox = (JCheckBox)e.getSource();
    String ac = checkBox.getActionCommand();
    if(ac.equals("number one")) {
        someComponent.setEnabled(checkBox.isSelected());
        anotherComponent.setEnabled(!anotherComponent.isEnabled());
    }
