Question

Hello,有一天。

因此,我用剪辑或封顶的曲线来撰写这一简单图象,当时你正在把<条码>-down或<条码>上页-up纽顿。

#include <curses.h>
#include <stdio.h>
#include <Windows.h>

int main(void)
{
    int ch;

    initscr();
    cbreak();
    keypad(stdscr,TRUE);
    idlok(stdscr,TRUE);
    scrollok(stdscr,TRUE);

    printw("Welcome!");
    refresh();


    ch = getch();
    while(ch !=  q ){
        if(ch == KEY_PPAGE){
            scrl(-1);
            refresh();
        }
        else
        {
            scrl(1);
            refresh();
        }
        ch = getch();
    }

    endwin();
    return 0;

}

The problem is that if the world "Welcome" goes out of the window , then you cannot bring it back with the opposite button. I thought that something like this will be solved by increasing window buffer. But don t know how such a thing will be done and if its good to be done.

是否有帮助我解决这一问题的想法?

Answer 1

I use curses in python, and the way I solve this issue is to have a list-like data structure attached to the window which holds all lines to be remembered, as well as an index which denotes the first visible line. From there you can figure out what lines should be visible, and recalculate as necessary.

一种是在假日使用可在https://gist.github.com/1622523” rel=“nofollow”> 查询。它不是在C,而是我希望它能够提供帮助。
