控制台鼠标输入不起作用 [英] Console Mouse Input not working

问题描述

我正在Visual Studio中使用c ++进行控制台项目，其中鼠标负责所有输入工作。
在Windows 7上可以正常工作，但在Windows 10上却不能。

I am working on a console project in c++ with visual studio, in which the mouse is doing all the input stuff. It is working fine on windows 7, but not on windows 10.

我将向您展示一些代码，这是我的一个非常简化的版本实际代码。但这是相同的：在win7上工作，而不在win 1上工作

I'll show you some code, which is a very simplefied version, of my actual code. But here is the same: working on win7, not on win 1

#include <stdio.h>
#include <windows.h>

void MouseEventProc(MOUSE_EVENT_RECORD);
VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD);
VOID KeyEventProc(KEY_EVENT_RECORD);
VOID GetInputEvents(VOID);
void gotoxy(int, int);

void MyErrorExit(char *s)
{
    printf("Fatal: %s\n", s);
    exit(1);
}

int main(void)
{
    HANDLE hStdin;
    DWORD cNumRead, fdwMode, fdwSaveOldMode, i;
    INPUT_RECORD irInBuf[128];

    // Get the standard input handle. 

    hStdin = GetStdHandle(STD_INPUT_HANDLE);
    if (hStdin == INVALID_HANDLE_VALUE)
        MyErrorExit("GetStdHandle");

    // Save the current input mode, to be restored on exit. 

    if (!GetConsoleMode(hStdin, &fdwSaveOldMode))
        MyErrorExit("GetConsoleMode");

    // Enable the window and mouse input events. 

    fdwMode = ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT;
    if (!SetConsoleMode(hStdin, fdwMode))
        MyErrorExit("SetConsoleMode");

    // Loop to read and handle the input events. 

    while (1)
    {

        // Wait for the events. 

        if (!ReadConsoleInput(
            hStdin,      // input buffer handle 
            irInBuf,     // buffer to read into 
            128,         // size of read buffer 
            &cNumRead)) // number of records read 
            MyErrorExit("ReadConsoleInput");

        // Dispatch the events to the appropriate handler. 

        for (i = 0; i < cNumRead; i++)
        {
            switch (irInBuf[i].EventType)
            {
            case KEY_EVENT: // keyboard input 
                KeyEventProc(irInBuf[i].Event.KeyEvent);
                break;

            case MOUSE_EVENT: // mouse input 
                MouseEventProc(irInBuf[i].Event.MouseEvent);
                break;

            case WINDOW_BUFFER_SIZE_EVENT: // scrn buf. resizing 
                ResizeEventProc(
                    irInBuf[i].Event.WindowBufferSizeEvent);
                break;

            case FOCUS_EVENT:  // disregard focus events 

            case MENU_EVENT:   // disregard menu events 
                break;

            default:
                MyErrorExit("unknown event type");
                break;
            }
        }
    }

    return 0;
}

VOID MouseEventProc(MOUSE_EVENT_RECORD ir)
{
    if (ir.dwEventFlags == MOUSE_MOVED)
        gotoxy(ir.dwMousePosition.X, ir.dwMousePosition.Y);
}

VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD dummy) { return; };
VOID KeyEventProc(KEY_EVENT_RECORD dummy) { return; };
VOID GetInputEvents(VOID) { return; };

void gotoxy(int x, int y)
{
    COORD coord;
    coord.X = x;
    coord.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

推荐答案

我有类似问题 。而且问题似乎是由于在Windows10的控制台Windows属性的设置中启用了快速编辑模式 选项引起的。我已经复制并粘贴了您指定的MCVE代码，但在Windows10计算机上也无法正常运行。但是，它按照 Microsoft有关禁用快速编辑模式的文档。在启用窗口&之前，我首先做了（em>禁用 这件事（！）。鼠标输入事件，方法是通过以下方式在您的代码中包含/添加快速编辑模式-禁用代码行：

I had similar problem on my Windows-10 machine. And the problem seemingly was being caused by 'Quick Edit Mode' option being enabled in settings of 'Console Windows Properties' on Windows10. I have copied and pasted your given MCVE-code, it wasn't working on my windows10 machine either. But, it started working after i disabled 'Quick Edit Mode' as per Microsoft's docs about disabling 'Quick Edit Mode'. I did this 'disabling' thing first(!), before enabling the window & mouse input events, by including/adding the 'Quick Edit Mode'-disabling-code-lines to your code in following manner:

    /* 
       Step-1:
       Disable 'Quick Edit Mode' option
    */
       fdwMode = ENABLE_EXTENDED_FLAGS;
       if (! SetConsoleMode(hStdin, fdwMode) )
           MyErrorExit("SetConsoleMode");
    /* 
       Step-2:
       Enable the window and mouse input events,
       after you have already applied that 'ENABLE_EXTENDED_FLAGS'
       to disable 'Quick Edit Mode'
    */
       fdwMode = ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT;
       if (!SetConsoleMode(hStdin, fdwMode))
           MyErrorExit("SetConsoleMode");

在包含上述内容之后，您的程序开始运行，并且控制台光标通过您的 gotoxy（）函数，按您提供的MCVE代码的预期，在我的 Windows10控制台上！

After this above-quoted inclusion, your program started working and the Console Cursor kept following my Mouse pointer via your gotoxy() function, as intended by your provided MCVE-code, on my Windows10-Console!
