About the List Master Example
This GUI, called List Master, lets its users manage multiple lists such as to-do
and shopping lists, cell phone numbers, catalogs of music or video recordings,
or any set of itemizations. It has the following features:
• Ability to create new GUIs from an existing List Master GUI
• A scrolling list box containing a numbered or unnumbered sequence of
items
• A text box and push buttons enabling users to edit, add, delete, and reorder
list items
• Capability to import and export list data and to save a list by saving the
GUI itself
A File menu handles creating, opening, and saving GUIs, and importing and
exporting list data. The followin g figure displays the File menu of a new ,
unpopulated, List Master GUI on the left. On the right is a sample GUI it
created, showing imported text data.
