SVG_SET_DOCUMENT_VARIABLE ( pointer )
| Parameter | Type | Description | |
|---|---|---|---|
| pointer | Pointer | → | Pointer to variable to set |
The SVG_SET_DOCUMENT_VARIABLE method sets a pointer to the variable of the host database that is updated after each call to SVG_SAVE_AS_PICTURE or SVG_SAVE_AS_TEXT. You must call this method only once per session (in an initialization method, for instance).
In the pointer parameter, you pass a pointer to the variable whose value you want to follow (usually the Document system variable).
You can pass a Nil pointer in the pointer parameter to remove the link.
