WkCheckBox provides a customizable version of a standard check box. It has a boolean value that is set to true when the box is checked and false when the box is unchecked. The value is toggled on and off by clicking on the check box. The state of a checkbox can be queried and changed using the #getState and #setState:notify: messages, respectively. Checkboxes call their valueChanged callback when their state is changed. The textual label that appears to the right of the check box can be changed at runtime with the #labelString: message.
