form_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 options are defined (all are on by default): O_VISIBLE The field is displayed. If this option is off, dis- play 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. O_NULLOK Allow a blank field. O_STATIC Field buffers are fixed to field's original size. Turn this option off to create a dynamic field. O_PASSOK Validate field only if modified by user.
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).
The header file <form.h> automatically includes the header file <curses.h>.
These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
