Abstract

This article describes an OS/2* Presentation Manager* (PM) control that allows the user to enter multi-line data where part of the data is restricted to only a set of certain allowable entries. The Multi- Line Value (MLV) control only allows the user to enter multi-line data, and the List control only allows the user to display multi- column data. This article describes the new Multi-Line/Restricted (MLR) control.

Restrictive Multiple Line Data Fields

       This article describes an OS/2* Presentation Manager*
(PM) control that allows the user to enter multi-line data where part
of the data is restricted to only a set of certain allowable entries.
The Multi- Line Value (MLV) control only allows the user to enter
multi-line data, and the List control only allows the user to display
multi- column data. This article describes the new
Multi-Line/Restricted (MLR) control.

      As an example of only one of the situations where this control
is needed, consider the user who wants to update a SQL data base
table by using a PM front-end (EUI).  One column in the table is the
name of the user, and a second column specifies whether this user has
write access to the table.  The only valid entries in the access
column are Y (Yes) and N (No).  The MLR control allows the user to
type in the name field, but restricts his data entry in the access
column to only a Y or N.  However, the user doesn't type anything
into this column at all, so there can be no data-entry error.

      The MLR control consists of a group of similar PM controls
positioned contiguously side-by-side.  In the case of the SQL table
data- entry described above, the user might need 2 columns for each
row, so the control is constructed as an MLV control on the left and
a List control on the right, except that the vertical scroll bar for
the MLV appears to the right of the List control. The MLV also has
checkboxes on the left, corresponding...
