public class CheckBoxSelector
extends AbstractCheckSelector

A Javascript-based "Select All" checkbox component that works with a loose collection of CheckBox components. By default, clicking on any of the controlled checkboxes automatically updates the state of the "select all" checkbox. Override AbstractCheckSelector.wantAutomaticUpdate() to change this.
