Description
The OBJECT Get multiline command returns the current state of the "Multiline" option for the object(s) designated by the object and * parameters.
You can set the "Multiline" option for an object using the Property List, or using the OBJECT SET MULTILINE command option.
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).
The value returned corresponds to one of the following constants, found in the "Form Objects (Properties)" theme:
| Constant | Type | Value | Comment |
|---|---|---|---|
| Multiline Auto | Longint | 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 | Longint | 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 | Longint | 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. |
Note: If you apply the OBJECT Get multiline command to an object that does not support the "Multiline" option, the command returns 0.
