如何找到鼠标按钮的“单击"位置x和y? [英] How to find the mouse button 'click' position x and y?

问题描述

我为搜索鼠标的x和y位置做了很多尝试 在C中的Windows控制台中单击，但是我找不到，所以我 在这里发布.

I tried a lot about searching for getting x and y position of mouse click inside the console of windows in C, but I cant find so I am posting here.

我正在创建自己的文本编辑器项目(出于娱乐目的)，并且我必须集成一项功能，每当我在控制台内单击时，光标就会移至该功能(单击x，y) 我不想知道如何移动光标，但是想知道如何获得点击位置.

I am creating my own text editor project (for fun) and I have to integrate a feature that whenever I click inside the console, the cursor moves to it (click x, y) I don't want to know how to move the cursor but I want to know how to get the click position.

此代码可以接收所有的鼠标和键盘以及鼠标事件，即使单击鼠标也是如此:

This code can receive all mouse and keyboard and mouse event even mouse clicked:

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

HANDLE hStdin;
DWORD fdwSaveOldMode;

VOID ErrorExit(LPSTR);
VOID KeyEventProc(KEY_EVENT_RECORD);
VOID MouseEventProc(MOUSE_EVENT_RECORD);
VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD);

int main(VOID)
{
    DWORD cNumRead, fdwMode, i;
    INPUT_RECORD irInBuf[128];
    int counter=0;

    // Get the standard input handle.

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

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

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

    // Enable the window and mouse input events.

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

    // Loop to read and handle the next 100 input events.

    while (counter++ <= 100)
    {
        // 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
            ErrorExit("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:
                    ErrorExit("Unknown event type");
                    break;
            }
        }
    }

    // Restore input mode on exit.

    SetConsoleMode(hStdin, fdwSaveOldMode);

    return 0;
}
VOID ErrorExit (LPSTR lpszMessage)
{
    fprintf(stderr, "%s\n", lpszMessage);

    // Restore input mode on exit.

    SetConsoleMode(hStdin, fdwSaveOldMode);

    ExitProcess(0);
}

VOID KeyEventProc(KEY_EVENT_RECORD ker)
{
    printf("Key event: ");
    if(ker.bKeyDown)
        printf("key pressed\n");
    else printf("key released\n");
}
VOID MouseEventProc(MOUSE_EVENT_RECORD mer)
{
    #ifndef MOUSE_HWHEELED
    #define MOUSE_HWHEELED 0x0008
    #endif
    printf("Mouse event: ");

    switch(mer.dwEventFlags)
    {
        case 0:

            if(mer.dwButtonState == FROM_LEFT_1ST_BUTTON_PRESSED)
            {
                printf("left button press \n");
            }
            else if(mer.dwButtonState == RIGHTMOST_BUTTON_PRESSED)
            {
                printf("right button press \n");
            }
            else
            {
                printf("button press\n");
            }
            break;
        case DOUBLE_CLICK:
            printf("double click\n");
            break;
        case MOUSE_HWHEELED:
            printf("horizontal mouse wheel\n");
            break;
        case MOUSE_MOVED:
            printf("mouse moved\n");
            break;
        case MOUSE_WHEELED:
            printf("vertical mouse wheel\n");
            break;
        default:
            printf("unknown\n");
            break;
    }
}
VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD wbsr)
{
    printf("Resize event\n");
    printf("Console screen buffer is %d columns by %d rows.\n",    wbsr.dwSize.X, wbsr.dwSize.Y);
}

我听说这不能在C语言中完成，但是如果当鼠标连续移动时我们获得鼠标位置，那么我相信我们可能会获得点击位置.但是我不知道怎么办.

I have heard that it can't be done in C, but if when we get mouse position when mouse is continuously moving then I am sure we may get the click position. But I don't know how.

推荐答案

例如，要获取用户双击要替换的位置，

For example to get the position the user double-clicked you want to replace:

printf("double click\n");

作者:

printf("double clicked at x=%d, y=%d\n", mer.dwMousePosition.X, mer.dwMousePosition.Y);
