Oracle Forms Developer – Form Builder Reference, Volume 1

Column Mapping Properties property
Description
The Column Mapping Properties group includes Column Name, Column Title, Display Width, and
Return Item.
Applies to LOV
Set Form Builder
Column Name
Specifies the names of the columns in an LOV.
Required/Optional At least one column must be defined.
Default
The names of the columns in the underlying record group.
Usage Notes
The column names must adhere to object naming standards.
Column Title
Specifies the title that displays above the column currently selected in the column name list.
Display Width
Specifies the width for the column currently selected in the Column Name list.
Required/Optional optional
Usage Notes
• Set the Display Width property to the width in appropriate units (points, pixels, centimeters, inches,
or characters as specified by the form’s Coordinate System property) that you want Form Builder to
reserve for the column in the LOV window. Column value truncation may occur if the Display
Width is smaller than the width of the column value. To avoid this situation, increase the Display
Width for the column.
• To make the column a hidden column, set Display Width to 0. (You can specify a return item for a
hidden column, just as you would for a displayed column.)
To add extra space between columns in the LOV window, set the Display Width wider than the column’s
default width. Note, however, that as an exception to this rule, you cannot increase the width between
a NUMBER column and a non-NUMBER column by increasing the display width for the NUMBER
column because LOVs display numbers right-justified. For example, assume that your LOV contains 3
columns: column 1 and 3 are type CHAR and column 2 is type NUMBER. To increase the width
between each column, increase the Display Width for columns 1 and 3.
Return Item
Specifies the name of the form item or variable to which Form Builder should assign the column’s value
whenever the operator selects an LOV record.
