141 Scrolling Lists
Publication 2711E-6.15 – November 1998
After you configure the Local Message Object List and any other
object lists that are part of the same Scrolling List, group the object
lists with the Cursor List. You must group all the components of the
Scrolling List at the same time or PanelBuilder will report a
validation error. For more information about grouping objects see
Chapter 9, Creating Objects, in the PanelBuilder 1400e
Configuration Software for Windows User Manual.
For an example of how to configure Local Message Object Lists that
would be displayed with your Cursor List, see “Scrolling List
Example” at the end of this chapter.
The number of Numeric Data Display objects in a list is determined
by the Number of States you defined for the Cursor List.
Configuring the Numeric Data Display Object List
Configure the Numeric Data Display Object List according to the
following table:
Field Meaning
Name Assign a name, up to 15 characters, to document the object for
printed reports. This increases the application’s size by 1 byte
per character.
Fill Left With You can choose whether the left portion of the display will be
filled with zeros or blank spaces, when fewer than the maximum
number of digits is displayed.
Number of Digits Specify the number of digits to display, up to a maximum of 16.
Keep in mind that a decimal point and minus sign each take the
place of one digit. If you choose to display several digits after
the decimal point, be sure to take these into account also.
Number of Visible
States Define the number of objects that the operator can see at any
given time. For the scrolling list to be valid, the Number of
Visible States must be the same as the Cursor List’s Number of
Visible States.
Highlight Bar Select this option if you want the current state (controlled by the
Cursor Control or cursor buttons) to appear highlighted.
Decimal Display How you configure the decimal display and polarity determines
the appearance and behavior of the Numeric Data Display. It
also determines the controls you must assign. Each Numeric
Data Display Object List can have only one configuration.
Disabled—Check this button if you do not want a decimal point
displayed. If the Visible State value contains a decimal point, it
is rounded off.
Implicit—The value from the Visible State control is displayed
as it is, without any external decimal position manipulation. For
example, a value of “1” is displayed as “1” and a value of “1.3”
is displayed as “1.3”. If the number of digits following the
decimal point is too large to fit in the display, the fraction is
rounded off to fit the number of digits. For example, if the
display has four digits, and the value is “1.237”, the display
shows “1.24”. If an integer value or the integer portion of a
number can’t be displayed fully, asterisks (***) are displayed.
