NAME

       form_field_opts - set and get field options


SYNOPSIS

       #include <form.h>
       int set_field_opts(FIELD *field, Field_Options opts);
       int field_opts_on(FIELD *field, Field_Options opts);
       int field_opts_off(FIELD *field, Field_Options opts);
       Field_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 standard options are defined (all are on  by
       default):

       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_AUTOSKIP
            Skip to the next field when this one fills.

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

       O_EDIT
            The field can be edited.

       O_NULLOK
            Allow a blank field.

       O_PASSOK
            Validate field only if modified by user.

       O_PUBLIC
            The field contents are displayed as data is entered.

       O_STATIC
            Field  buffers  are  fixed  to field's original size.
            Turn this option off to create a dynamic field.

       O_VISIBLE
            The field is displayed.  If this option is off,  dis-
            play of the field is suppressed.

       O_WRAP
            Words  that  do  not fit on a line are wrapped to the
            next line.  Words are blank-separated.

       One extension option is defined  (extensions  are  off  by
       default):

       O_DYNAMIC_JUSTIFY
            Permit  dynamic  fields  to be justified, like static
            fields.


RETURN VALUE

       Except for field_opts, each routine  returns  one  of  the
       following:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine  detected  an incorrect or out-of-range argu-
            ment.

       E_CURRENT
            The field is the current field.

       E_SYSTEM_ERROR
            System error occurred (see errno).
