int set_field_opts(FIELD *field, Field_Options opts);

.SH DESCRIPTION
|
|
The function \fBset_field_opts\fR sets all the given field's option bits (field
|
|
option bits may be logically-OR'ed together).
|
|
.PP
|
|
The function \fBfield_opts_on\fR turns on the given option bits, and leaves
|
|
others alone.
|
|
.PP
|
|
The function \fBfield_opts_off\fR turns off the given option bits, and leaves
|
|
others alone.
|
|
.PP
|
|
The function \fBfield_opts\fR returns the field's current option bits.
|
|
.PP
|
|
The following standard options are defined (all are on by default):
|
|
.TP 5
|
|
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.
|
|
.TP 5
|
|
O_AUTOSKIP
|
|
Skip to the next field when this one fills.
|
|
.TP 5
|
|
O_BLANK
|
|
The field is cleared whenever a character is entered at the first position.
|
|
.TP 5
|
|
O_EDIT
|
|
The field can be edited.
|
|
.TP 5
|
|
O_NULLOK
|
|
Allow a blank field.
|
|
.TP 5
|
|
O_PASSOK
|
|
Validate field only if modified by user.
|
|
.TP 5
|
|
O_PUBLIC
|
|
The field contents are displayed as data is entered.
|
|
.TP 5
|
|
O_STATIC
|
|
Field buffers are fixed to field's original size.
|
|
Turn this option off to create a dynamic field.
|
|
.TP 5
|
|
O_VISIBLE
|
|
The field is displayed.
|
|
If this option is off, display of the field is
|
|
suppressed.
|
|
.TP 5
|
|
O_WRAP
|
|
Words that do not fit on a line are wrapped to the next line.
|
|
Words are
|
|
blank-separated.
|
|
.PP
|
|
These extension options are defined (extensions are off by default):
|
|
.TP 5
|
|
O_DYNAMIC_JUSTIFY
|
|
Permit dynamic fields to be justified, like static fields.
|
|
.TP 5
|
|
O_NO_LEFT_STRIP
|
|
Preserve leading whitespace in the field buffer, which is normally discarded.
|
|
.TP 5
|
|
O_EDGE_INSERT_STAY
|
|
When inserting into a field up to the boundary position,
|
|
optionally delay the scrolling,
|
|
so that the last inserted character remains visible,
|
|
but advance the cursor to reflect the insertion.
|
|
This allows the form library to display the
|
|
inserted character in one-character fields
|
|
as well as allowing the library to maintain consistent state.
|
|
.TP 5
|
|
O_INPUT_FIELD
|
|
The \fBset_max_field\fP function checks for this extension,
|
|
which allows a dynamic field to shrink if the new
|
|
limit is smaller than the current field size.
|
|
.SH RETURN VALUE
|
|
Except for \fBfield_opts\fR, each routine returns one of the following:
|
|
.TP 5
|
|
.B E_OK
|
|
The routine succeeded.
|
|
.TP 5
|
|
.B E_BAD_ARGUMENT
|
|
Routine detected an incorrect or out-of-range argument.
|
|
.TP 5
|
|
.B E_CURRENT
|
|
The field is the current field.
|
|
.TP 5
|
|
.B E_SYSTEM_ERROR
|
|
System error occurred (see \fBerrno\fR(3)).
