c++ - 如何删除控制台窗口 C++ 中的滚动条

Question

我一直在查看一些 Rogue like games (Larn、Rogue 等)是用 C 和 C++ 编写的，我注意到它们在控制台窗口右侧没有滚动条。

我怎样才能完成同样的功能？

要删除滚动条，只需将屏幕缓冲区高度设置为与窗口高度相同:

#include <windows.h>
#include <iostream>
using namespace std;

int main()
{                
    // get handle to the console window
    HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);

    // retrieve screen buffer info
    CONSOLE_SCREEN_BUFFER_INFO scrBufferInfo;
    GetConsoleScreenBufferInfo(hOut, &scrBufferInfo);

    // current window size
    short winWidth = scrBufferInfo.srWindow.Right - scrBufferInfo.srWindow.Left + 1;
    short winHeight = scrBufferInfo.srWindow.Bottom - scrBufferInfo.srWindow.Top + 1;

    // current screen buffer size
    short scrBufferWidth = scrBufferInfo.dwSize.X;
    short scrBufferHeight = scrBufferInfo.dwSize.Y;        

    // to remove the scrollbar, make sure the window height matches the screen buffer height
    COORD newSize;
    newSize.X = scrBufferWidth;
    newSize.Y = winHeight;

    // set the new screen buffer dimensions
    int Status = SetConsoleScreenBufferSize(hOut, newSize);
    if (Status == 0)
    {
        cout << "SetConsoleScreenBufferSize() failed! Reason : " << GetLastError() << endl;
        exit(Status);
    }

    // print the current screen buffer dimensions
    GetConsoleScreenBufferInfo(hOut, &scrBufferInfo);
    cout << "Screen Buffer Size : " << scrBufferInfo.dwSize.X << " x " << scrBufferInfo.dwSize.Y << endl;

    return 0;
}
