49 The function \fBset_field_opts\fR sets all the given field's option bits (field
50 option bits may be logically-OR'ed together).
52 The function \fBfield_opts_on\fR turns on the given option bits, and leaves
55 The function \fBfield_opts_off\fR turns off the given option bits, and leaves
58 The function \fBfield_opts\fR returns the field's current option bits.
60 The following standard options are defined (all are on by default):
63 The field is visited during processing. If this option is off, the field will
64 not be reachable by navigation keys. Please notice that an invisible field
65 appears to be inactive also.
68 Skip to the next field when this one fills.
71 The field is cleared whenever a character is entered at the first position.
74 The field can be edited.
80 Validate field only if modified by user.
83 The field contents are displayed as data is entered.
86 Field buffers are fixed to field's original size.
87 Turn this option off to create a dynamic field.
