I'm programming in C using ncurses libraries (it's the first time) and I've two problems. I'm on ubuntu with the default terminal (gnome terminal).
1) I need to resize the terminal. I used resizeter() and resize_term(), but they fail.
2) I use scrollok() function and the problem is that I lose scrolled lines (when I get back with wscrl(), there are blank lines).
#include <ncurses.h>
int main() {
WINDOW *win, *win2;
int i;
char c;
initscr();
cbreak();
noecho();
win=newwin(8,20,1,1);
box(win,0,0);
win2=newwin(6,18,2,2);
scrollok(win2,1);
wrefresh(win);
wrefresh(win);
for(i=0;i<15;i++){
c=wgetch(win2);
if(c=='u'){
wscrl(win2,-1);
wrefresh(win2);
}
else{
wprintw(win2,"%c\n",c);
wrefresh(win2);
}
}
delwin(win);
delwin(win2);
endwin();
return 0;
}
