Creating a JCheckbox Component
By default, the state of the checkbox is off; to change the state, see
Getting and Setting the State of a JCheckbox Component. Also by default, the
checkbox is left-justified and vertically centered. The methods to
control the text alignment are identical to those of a JButton;
see Moving the Label/Icon Pair in a JButton Component.
// Create an action
Action action = new AbstractAction("CheckBox Label") {
// This method is called when the button is pressed
public void actionPerformed(ActionEvent evt) {
// Perform action
JCheckBox cb = (JCheckBox)evt.getSource();
// Determine status
boolean isSel = cb.isSelected();
if (isSel) {
// The checkbox is now selected
} else {
// The checkbox is now deselected
}
}
};
// Create the checkbox
JCheckBox checkBox = new JCheckBox(action);
