_EdIndent( ) API Library Routine

Visual FoxPro 9.0 SP2

_EdIndent( ) API Library Routine


void _EdIndent(WHANDLE wh, int tabstops) WHANDLE wh; /* Handle of editing window. / int tabstops; / Number of tab stops. */

Remarks

You can specify a negative number for tabstops to cause a hanging indent for the selection.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.

Example

The following example opens an editing session for a file specified by a parameter, and indents lines 13 and 15 in the file by a single tab stop.
