2.4.19 LIST BOX - SET SLIDER A (AES 175, 0)

This function positions Slider A and draws it within the redraw rectangle <rect>. The contents of the list box will not be updated, so one may have to call lbox_update(). If <rect> is 0L, then only the position of the slider objects will be altered, but the objects will not be drawn.

Declaration:
void lbox_set_slider( LIST_BOX *box, WORD first, GRECT *rect );

Call:
lbox_set_slider( box, first, &rect );
       or
lbox_set_asldr( box, first, &rect );
