 Name:         »Edit Object Set Format« - Alter settings: Formating

 Opcode:       217 (sub-opcode 1)

 Syntax:       void edit_set_format ( OBJECT *tree, int16_t obj, 
               int16_t tabwidth, int16_t autowrap );

 Description:  The call edit_set_format sets the formatting of text in 
               an editable object. The following apply:

                Parameter  Meaning

                tree       Object tree
                obj        Object index
                tabwidth   1 or tabulator width in pixels
                autowrap    -1: Do not change
                           > 0: Pixel width for auto line wrap 
                           (generally == object width)
                           = 0: No wrapping, but horiz. scrolling

               If one of the two attributes is to remain unchanged 
               then -1 can be passed.

               If the editable object was opened previously then one 
               should generally trigger a redraw when changing one of 
               the attributes. From version 9 of the SLB the number of 
               lines is recalculated when the autowrap setting is 
               altered. In older versions this only happens with 
               edit_set_buf.

 Return value: The function does not return a result.

 Availability: As of MagiC 5.20 by means of a shared library.

 Group:        Editable object functions
