4.2.2 Dialogs

A dialog is a screen type used to get detailed input from the operator, for example a
SCSI ID, a name or a password. See Figure 4.6.

Figure 4.6 Standard Dialog Layout.

The dialogs come in several forms, but there are only a few main types.
Dialogs, Discrete Values
The dialog in Figure 4.7 is used to enter discrete values. It handles one character or
digit at a time. The digit or character being manipulated is said to be in focus. The
digit or character in focus is shown in inverse video. As the character map on the
screen used restricts the flexibility of the inverse display of the character, some
digits and characters may appear to be mutilated when inverted. For example, the
"0" digit appears as an open rectangle when inverted.
The Up and Down arrows on the left are used to increment (up arrow) or decrement
(down arrow) the value of the character or digit in focus. If increment is selected and
the value of the character of digit in focus is at its highest legal value, it wraps to its
lowest legal value and vice versa.

The Right arrow (on the right) is used to shift the focus one place to the right. If the
focus is already at the rightmost position, the focus wraps to the leftmost position.
The Ok button is used to accept the value displayed.
If the value was changed, the selected and original values will then be displayed as
messages. The operator may then accept or reject the change.
The discrete value type of dialog does a running check of the validity of what the
user enters, and changes it if needed.
Examples: If the value "0" or "1" is selected in the Fixed IP address dialog
above, the user is allowed to select values between "0" and "9" as the
next two digits. (The maximum value allowed in this dialog is "255"
within each group.) If, however, "2" is selected, only values between
"0" and "5" are available in the second digit. If a value between "0"
