form_field_opts(3)  UNIX Programmer's Manual   form_field_opts(3)

NAME

     form_field_opts - set and get field options

SYNOPSIS

     #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

     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 do not 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.
