win32:模拟点击而不模拟鼠标移动? [英] win32: simulate a click without simulating mouse movement?

问题描述

我正在尝试模拟在窗口上单击鼠标.我目前按如下方式成功执行此操作(我使用的是 Python，但它应该适用于一般的 win32):

I'm trying to simulate a mouse click on a window. I currently have success doing this as follows (I'm using Python, but it should apply to general win32):

win32api.SetCursorPos((x,y))
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0)
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)

这很好用.但是，如果在我手动移动鼠标时发生点击，光标位置会被抛出.有没有办法直接将点击发送到给定的 (x,y) 坐标而无需将鼠标移动到那里?我尝试过类似以下的方法，但运气不佳:

This works fine. However, if the click happens while I'm moving the mouse manually, the cursor position gets thrown off. Is there any way to send a click directly to a given (x,y) coordinate without moving the mouse there? I've tried something like the following with not much luck:

nx = x*65535/win32api.GetSystemMetrics(0)
ny = y*65535/win32api.GetSystemMetrics(1)
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN | 
                     win32con.MOUSEEVENTF_ABSOLUTE,nx,ny)
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP | 
                     win32con.MOUSEEVENTF_ABSOLUTE,nx,ny)

推荐答案

尝试 WindowFromPoint() 函数:

Try WindowFromPoint() function:

POINT pt;
    pt.x = 30; // This is your click coordinates
    pt.y = 30;

HWND hWnd = WindowFromPoint(pt);
LPARAM lParam = MAKELPARAM(pt.x, pt.y);
PostMessage(hWnd, WM_RBUTTONDOWN, MK_RBUTTON, lParam);
PostMessage(hWnd, WM_RBUTTONUP, MK_RBUTTON, lParam);
