Curses Programming 1

[GouseBaig]

Hi everybody,

I am working on a solaris box using vt100 terminal. I didnt have xterm or any graphic supported terminals.

I need to write a small applications having a screen and some menu options. Based on the user selection on menus , it has to fetch some data from file/database and display, some time draw a form and capture the input from the user and etc ...

I didnt tried anything with curses/ncurses. I need guidlines to start on this. I need some usefull reference sites or if any one can send some sample programs also will help me.

Any Small help will be appriciated.


Thanx
baig.

Thanx saleem and singh.

I was going through those links and its good.

But I am not able to find any solid examples for menu programs using curses.

I am trying to create a screen with menus. I have written a small sample program, its getting failed and I need to close my terminal since my prompt messages are becoming junk.

Here is that sample program.

============================================================
#include <menu.h>

int main ()
{
WINDOW *w [2] ;

ITEM *menu1_items [4] ;

MENU *menu1 ;

OPTIONS opts ;

int index ;

initscr () ;
refresh () ;

w [1] = stdscr ;
scrollok ( w[1], TRUE ) ;
box ( w[1], '*', '*' ) ;

touchwin ( w[1] ) ; wrefresh ( w[1] ) ;

menu1_items [0] = new_item ( &quot;Add&quot; , &quot;Add-&quot; ) ;
menu1_items [1] = new_item ( &quot;Delete&quot; , &quot;Delete-&quot; ) ;
menu1_items [2] = new_item ( &quot;List&quot; , &quot;List-&quot; ) ;
menu1_items [3] = new_item ( &quot;Update&quot; , &quot;Update-&quot; ) ;

menu1 = new_menu ( menu1_items ) ;

opts = O_ONEVALUE | O_SHOWDESC | O_SHOWMATCH | O_ROWMAJOR | O_IGNORECASE ;
set_menu_opts ( menu1, opts ) ;

set_menu_format ( menu1, 3, 1) ;

post_menu ( menu1 ) ;

refresh () ;
wrefresh ( w[1] ) ;

getch () ;

unpost_menu ( menu1 ) ;

for (index = 0 ; index <= 3 ; index ++ )
{
free_item ( menu1_items [ index ] ) ;
}

free_menu ( menu1 ) ;

endwin () ;

}

============================================================

I am unable to find the problem.

If anyone help me by giving solid example programs with menus and multi screens, it will be great.

Thanks and Regards
baig.
