About JCheckBox

[Sameer]

What is the method to check whether a given JCheckButton is in selected
state or not?
I searched the API documentation for the same but was not able to find
it.

Do I have to code like following?

jcheckBox.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
if (e.getStateChange() == ItemEvent.SELECTED) {

// 'selected' stuff
}
else {

// 'non selected' stuff
}
}
}
);

Sun 'hid' it in a superclass.

Do a 'Find' on 'ssel' (SSEL).

When searching the docs, you always need to keep in mind that whatever class
you're looking at also inherits all public and protected methods from ALL
its parent classes.

So when searching for a method you may also need to either walk the
inheritance hierarchy "up stream", or analyse the javadoc sections entitled
"Methods inherited from xxxxxxxx"

Checkbox uses getState and setState, where JCheckBox uses isSelected
and setSelected.
