Checkbox
Checkbox Widget. Caution is not to make series of check boxes operate like radio buttons. Check boxes let users
to make independent choices: checking one box does not aotomatically uncheck all the others in a group. That't not to
say there might not be some connection among check boxes in a group. For example, it is not out of the question to script
the checkbox that clicking it will automatically checks other related checkboxes. Because a check box widget is a simple type of
the button, its methods are very similar to the button widget.
