+----Prompter
- public class Prompter
- extends Object
Provides a dialog box prompt for user input of long and double values. The dialog
is modal and does not return (unless specifically cancelled) until the user enters a
valid value of the right type.
To use a Prompter, create one, passing it a Frame (NOT null).
You then just call getLong, getDouble... supplying a prompt string that informs
the user what is required. A dialog box will be put up with a button labeled
with the type of data required. The user pushes this button when data have been
added to the Reply field. The dialog will not accept illegal values.
The cancel button will cancel the function and will return default values (zero).
