如何在ncurses中获得正确大小的窗口 [英] how to get a correctly sized window in ncurses

问题描述

我正在尝试在Linux(Mint)上用C语言进行ncurses编程，并且遇到了一个奇怪的问题.我一直在获取窗口的第一行和最后一行具有错误的列数.例如，使用此代码可在StackOverflow上找到

I am trying out ncurses programming in C on Linux (Mint) and am having a strange problem. I keep getting windows with the wrong number of columns for the first and final lines. For example, with this code found on StackOverflow

#include <ncurses.h>
int main(){
  initscr();

  WINDOW * win = newwin(10,50,10,10);
  box(win,0,0);
  wrefresh(win);

  wgetch(win);
  endwin();
  return 0;
}

我得到以下输出:

          ┌─┐
          │                                                │
          │                                                │
          │                                                │
          │                                                │
          │                                                │
          │                                                │
          │                                                │
          │                                                │
          └─┘

好像第一行和最后一行只有三列宽.如果我使用waddch向窗口添加文本，那么我也只能在顶部一行添加三个字符.

As if the first and final lines are only three columns wide. If I add text to the window, using waddch, I can only add three characters to the top line as well.

任何帮助将不胜感激，我在网络上找不到其他人遇到此问题的示例，但这并不是最简单的选择一个好的搜索字符串的方法.

Any help would be appreciated, I can't find examples of other people running into this issue on the web, but it's not the easiest thing to come up with a good search string for.
