/*
 * To Do:
 *
 * - Fix function naming to be classItemVerb (checkboxValueGet instead of checkboxGetValue)
 * - Replace any direct data manipulation from outside a class with methods to handle it
 * - More widget states:  Ghosted, hidden
 * - Move setup math for paint events inside the dirty check
 * - Methods that can change the width of a widget (such as setTitle) need to repaint the parent window as well
 *
