set_field_opts, field_opts_on, field_opts_off, field_opts - set and
get field options
#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);
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, display 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.
These extension options are defined (extensions are off by default):
O_DYNAMIC_JUSTIFY
Permit dynamic fields to be justified, like static fields.
O_NO_LEFT_STRIP
Preserve leading whitespace in the field buffer, which is
normally discarded.
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 argument.
E_CURRENT
The field is the current field.
E_SYSTEM_ERROR
System error occurred (see errno).
