Chapter 7. The Listbox Widget
A listbox widget is designed to list
strings of text, one text string per line. You can then select a line
or multiple lines from the listbox to perform other operations on.
Some examples of things to place inside a listbox:
An alphabetized list of cities.
A list of servers to log in to. Select a server name and then enter a name and password into some entry widgets. Click the OK button to log in.
A list of operating systems.
A list of payment options: MasterCard, American Express, Visa, Check, Cash.
A listbox is ideal for replacing radiobuttons or checkboxes that have become too numerous to display on the screen. Usually 3 or 4 checkbuttons or radiobuttons aren't a big deal, but if you had to try to display 10 at a time, the window could get a little crowded. A group of radiobuttons can be replaced by a listbox that limits the number of selections to one and has a default selection. A bunch of checkbuttons can be replaced by a listbox that allows multiple selections.
