Updating the Form Background

You can update the background items on the form by calling fm_updbg(). fm_updbg() can be called for menus as well as for data forms. The call for fm_updbg() is as follows:

void fm_updbg(fmp)

FORMPTR fmp;        /* Data form or menu to update            */

Before calling this function, the form must be displayed on the screen or made ready by calling fm_ready().

fm_updbg() goes through the linked list of background items for the form, redisplaying each on the form window.
