#include <form.h> int main(void) { int ch; FORM *formp; FIELD *fields[3]; initscr(); cbreak(); noecho(); keypad(stdscr, TRUE); fields[0] = new_field(1, 32, 4, 18, 0, 0); fields[1] = new_field(4, 32, 6, 18, 0, 0); fields[2] = NULL; set_field_back(fields[0], A_STANDOUT); field_opts_off(fields[0], O_AUTOSKIP); set_field_back(fields[1], A_STANDOUT); field_opts_off(fields[1], O_AUTOSKIP); formp = new_form(fields); post_form(formp); refresh(); mvprintw(4, 5, "IP Address:"); mvprintw(6, 5, "Message:"); move(4, 18); refresh(); while( (ch = getch()) != KEY_F(1) ) { switch(ch) { case KEY_DOWN: form_driver(formp, REQ_NEXT_FIELD); form_driver(formp, REQ_END_LINE); break; case KEY_UP: form_driver(formp, REQ_PREV_FIELD); form_driver(formp, REQ_END_LINE); break; default: form_driver(formp, ch); break; } } unpost_form(formp); free_form(formp); free_field(fields[0]); free_field(fields[1]); endwin(); return 0; }

compile with:

 gcc -lform -g test.c -o test
