如何在 Win 上不移动鼠标的情况下发送点击事件？

Question

I'm trying to write a function to allow me to send a left click to x, y co-ordinates on screen without my mouse cursor moving.

I've read through the send message documentation and the mouse input notification documentation and I've come up with a few different approaches, none of which work. And none throw an error.

I'm using win32gui.FindWindow to get the hwnd and then I've tried using both PostMessage and SendMessage to perform the click, none so far work.

import win32api, win32gui, win32con

def control_click(x, y):

    hWnd = win32gui.FindWindow(None, "Pixel Starships")
    l_param = win32api.MAKELONG(x, y)

    if button == 'left':
        win32gui.PostMessage(hWnd, win32con.WM_LBUTTONDOWN, win32con.MK_LBUTTON, l_param)
        win32gui.PostMessage(hWnd, win32con.WM_LBUTTONUP, win32con.MK_LBUTTON, l_param)
   
control_click(526, 694)

def click(x, y):
    hWnd = win32gui.FindWindow(None, "Pixel Starships")
    lParam = win32api.MAKELONG(x, y)

    win32api.SendMessage(hWnd, win32con.WM_LBUTTONDOWN, win32con.MK_LBUTTON, lParam)
    win32api.SendMessage(hWnd, win32con.WM_LBUTTONUP, win32con.MK_LBUTTON, lParam)

click(526,694)

def leftClick(pos):
    hWnd = win32gui.FindWindow(None, "Pixel Starships")
    lParam = win32api.MAKELONG(pos[0], pos[1])

    win32gui.SendMessage(hWnd, win32con.WM_LBUTTONDOWN, win32con.MK_LBUTTON, lParam) 
    win32gui.SendMessage(hWnd, win32con.WM_LBUTTONUP, 0, lParam)

leftClick([526,964])

What do I need to do to get this function to work?

Answer 1

Could this work?

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

I would also recommend trying pyautogui . It might help.

Answer 2

I would also recommend using pyautogui because afaik it has a function to generate a click at a specific position without changing current cursor location.

Also you probably want to have a couple of milliseconds between button-down and button-up function because windows sometimes tend to not register the second button function due to beeing to fast after the button down. Additionally if this is for a game (pixel starships), you want to randomize this milliseconds waitingframe. Otherwise you might run into anti-bot checks and get dispelled/banned from the game server if pixel starships implements those.

Answer 3

I have been looking for an answer to this question for over 2 years. I have tried all possible scripts, nothing worked (well, pywinauto works fine in a lot of cases, but with some apps, it doesn't). I found something yesterday that I want to share with you. It is not a script for mouse clicks, but for keystrokes. However, it might be the way to solve your (our) problem. I have tested it already with some apps that gave me trouble sending keystrokes, and it worked like a charm. I hope I can get it to run with mouse clicks. Keep us informed if you find something, I will also keep looking for a solution.

https://github.com/byt3bl33d3r/Invoke-AutoIt

Loads the AutoIt DLL and PowerShell assemblies into memory and executes the specified keystrokes.

This was mainly created to bypass some application restrictions when it came to sending keystroke input via sendkeys(), sendinput() or sendmessage(). eg Windows's Remote Desktop Client ;)

Maybe you can try with Pywinauto is another library similar to PyAutoGUI, but allows you to manipulate apps via her control identifier.

import pywinauto
app = pywinauto.Application().connect(path='notepad.exe')
app.UntitledNotepad.MenuSelect("Edit->Replace")
