OBJECT SET MULTILINE
OBJECT SET MULTILINE ( {* ;} object ; multiline )
| Parameter | Type | Description | |
|---|---|---|---|
| * | Operator | → | If specified, object is an object name (string) If omitted, object is a field or variable |
| object | any | → | Object name (if * is specified) or Field or variable (if * is omitted) |
| multiline | Integer | → | Status of multiline property |
Description
The OBJECT SET MULTILINE command modifies the "Multiline" property of the object(s) designated by the object and * parameters.
The "Multiline" property controls two parameters related to the display and printing of text areas: display of words located at the end of the line in single-line areas and the automatic insertion of line returns. For more information, refer to Multiline in the Design Reference manual. If you apply this command to an object that does not support this property, the command does nothing.
Passing the optional * parameter indicates that the object parameter is an object name (string). If you do not pass this parameter, it indicates that the object parameter is a field or variable. In this case, you pass a field or variable reference instead of a string (field or variable object only).
In the multiline parameter, pass the new value of the option that you want to set. You can use the following constants, found in the "Form Objects (Properties)" theme:
| Constant | Type | Value | Comment |
|---|---|---|---|
| Multiline Auto | Integer | 0 | In single-line areas, words located at the end of lines are truncated and there are no line returns. In multiline areas, 4D carries out automatic line returns. |
| Multiline No | Integer | 2 | There are never line returns: the text is always displayed on a single row. If the Alpha or Text field or variable contains carriage returns, the text located after the first carriage return is removed as soon as the area is modified. |
| Multiline Yes | Integer | 1 | In single-line areas, the text is displayed up to the first carriage return or until the last word that can be displayed entirely. 4D inserts line returns; it is possible to scroll the contents of the area by pressing the down arrow key. In multiline areas, 4D carries out automatic line returns. |
Example
You want to prohibit multiple lines in an entry area:
