如何使用SetConsoleCursorPosition函数

Question

我刚刚用 c 语言编写了河内塔的代码，我想使用字符以图形模式显示解决方案。

我想使用 windows.h 和

SetConsoleCursorPosition

函数在控制台中移动光标。

您能帮我告诉我这个功能是否有效以及如何使用它吗？请举一些例子。

Answer 1

这里有一个如何调用

SetConsoleCursorPosition

函数的示例，摘自 cplusplus:

void GoToXY(int column, int line)
{
    // Create a COORD structure and fill in its members.
    // This specifies the new position of the cursor that we will set.
    COORD coord;
    coord.X = column;
    coord.Y = line;

    // Obtain a handle to the console screen buffer.
    // (You're just using the standard console, so you can use STD_OUTPUT_HANDLE
    // in conjunction with the GetStdHandle() to retrieve the handle.)
    // Note that because it is a standard handle, we don't need to close it.
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    // Finally, call the SetConsoleCursorPosition function.
    if (!SetConsoleCursorPosition(hConsole, coord))
    {
        // Uh-oh! The function call failed, so you need to handle the error.
        // You can call GetLastError() to get a more specific error code.
        // ...
    }
}

您还可以通过查看SDK文档来了解如何使用Win32函数。谷歌搜索该函数的名称通常会显示相应的文档页面作为第一个命中。

Answer 2

  include <Windows.h>
HANDLE desc = GetStdHandle(STD_OUTPUT_HANDLE);//getting the console handle
void ConsoleCursor(bool show, short size) {
    CONSOLE_CURSOR_INFO CursorInfo;
    GetConsoleCursorInfo(desc, &CursorInfo);
    CursorInfo.bVisible = show;
    CursorInfo.dwSize = size;
    SetConsoleCursorInfo(desc, &CursorInfo);
}
void CurPos(short x, short y) {
    SetConsoleCursorPosition(desc, { x, y });
    /*
similarly:
COORD pos ;
pos.X = 50 ;
pos.Y = 12 ;
SetConsoleCursorPosition(desc, pos);
*/ 
}
