public class ContribCheckbox
extends Checkbox
The Checkbox class in the Java AWT does not allow a value to be associated with the checkbox. ContribCheckbox does allow this through the value member variable. ContribCheckbox also contains two functions for building groups of checkboxes: makeGroup() takes an array of labels and an array of values and creates a group of radio buttons with associated values for each button. makeCollection() takes the same parameters and produces an array of individual check boxes. In combination with ContribCheckboxGroup, these functions can simplify the creation of checkboxes. The .class files are also reduced in size.
