NAME
| | form_field_new, new_field, dup_field, link_field, free_field - create and destroy forms fields |
SYNOPSIS
| |
cc [ flag... ] file... -lform -lcurses [ library... ]
#include <form.h> FIELD *new_field(int r, int c, int frow, int fcol, int nrow, int ncol); |
| | FIELD *dup_field(FIELD *field, int frow, int fcol); |
| | FIELD *link_field(FIELD *field, int frow, int fcol); |
| | int free_field(FIELD *field); |
| |
new_field() creates a new field with r rows and c columns, starting at frow, fcol, in the subwindow
of a form. nrow is the number of off-screen rows and nbuf is the number of additional working buffers. This routine returns a pointer to the new field.
dup_field() duplicates field at the specified location. All field attributes are duplicated, including the current contents of the field buffers.
link_field() also duplicates field at the specified location. However, unlike dup_field(), the new field shares the field buffers with the original field. After creation, the attributes of the new field can be changed without affecting
the original field.
free_field() frees the storage allocated for field.
|
| |
Routines that return pointers return NULL on error. free_field() returns one of the following:
- E_OK
- Thefunction returned successfully.
- E_CONNECTED
- The field is already connected to a form.
- E_SYSTEM_ERROR
- System error.
- E_BAD_ARGUMENT
- An argument is incorrect.
