NAME    [Toc]    [Back]

       form_field_opts - set and get field options

SYNOPSIS    [Toc]    [Back]

       #include <form.h>
       int set_field_opts(FIELD *field, OPTIONS opts);
       int field_opts_on(FIELD *field, OPTIONS opts);
       int field_opts_off(FIELD *field, OPTIONS opts);
       OPTIONS field_opts(const FIELD *field);

DESCRIPTION    [Toc]    [Back]

       The  function  set_field_opts  sets  all  the given field's option bits
       (field option bits may be logically-OR'ed together).

       The function field_opts_on turns on the given option bits,  and	leaves
       others alone.

       The function field_opts_off turns off the given option bits, and leaves
       others alone.

       The function field_opts returns the field's current option bits.

       The following options are defined (all are on by default):

       O_VISIBLE
	    The field is displayed.  If this option is	off,  display  of  the
	    field is suppressed,

       O_ACTIVE
	    The  field	is  visited during processing.	If this option is off,
	    the field will not be reachable by navigation keys. Please	notice
	    that an invisible field appears to be inactive also.

       O_PUBLIC
	    The field contents are displayed as data is entered.

       O_EDIT
	    The field can be edited.

       O_WRAP
	    Words  that  don't	fit  on  a  line are wrapped to the next line.
	    Words are blank-separated.

       O_BLANK
	    The field is cleared whenever a character is entered at the  first
	    position.

       O_AUTOSKIP
	    Skip to the next field when this one fills

       O_NULLOK
	    Allow a blank field.

       O_STATIC
	    Field buffers are fixed to field's original size.

       O_PASSOK
	    Validate field only if modified by user.
