Ctypes mouse_events

Question

ctypes.windll.user32.mouse_event (3, 0, 0, 0,0)

I fumbled with mouse positions and stumbled upon this line, which from what I understand emulates a mouse click. Does anyone have documentation for similar strings (e.g. right click, etc.)?

Answer 1

I have a small class that wraps mouse controls.

import win32gui, win32api, win32con, ctypes class Mouse: """It simulates the mouse""" MOUSEEVENTF_MOVE = 0x0001 # mouse move MOUSEEVENTF_LEFTDOWN = 0x0002 # left button down MOUSEEVENTF_LEFTUP = 0x0004 # left button up MOUSEEVENTF_RIGHTDOWN = 0x0008 # right button down MOUSEEVENTF_RIGHTUP = 0x0010 # right button up MOUSEEVENTF_MIDDLEDOWN = 0x0020 # middle button down MOUSEEVENTF_MIDDLEUP = 0x0040 # middle button up MOUSEEVENTF_WHEEL = 0x0800 # wheel button rolled MOUSEEVENTF_ABSOLUTE = 0x8000 # absolute move SM_CXSCREEN = 0 SM_CYSCREEN = 1 def _do_event(self, flags, x_pos, y_pos, data, extra_info): """generate a mouse event""" x_calc = 65536L * x_pos / ctypes.windll.user32.GetSystemMetrics(self.SM_CXSCREEN) + 1 y_calc = 65536L * y_pos / ctypes.windll.user32.GetSystemMetrics(self.SM_CYSCREEN) + 1 return ctypes.windll.user32.mouse_event(flags, x_calc, y_calc, data, extra_info) def _get_button_value(self, button_name, button_up=False): """convert the name of the button into the corresponding value""" buttons = 0 if button_name.find("right") >= 0: buttons = self.MOUSEEVENTF_RIGHTDOWN if button_name.find("left") >= 0: buttons = buttons + self.MOUSEEVENTF_LEFTDOWN if button_name.find("middle") >= 0: buttons = buttons + self.MOUSEEVENTF_MIDDLEDOWN if button_up: buttons = buttons << 1 return buttons def move_mouse(self, pos): """move the mouse to the specified coordinates""" (x, y) = pos old_pos = self.get_position() x = x if (x != -1) else old_pos[0] y = y if (y != -1) else old_pos[1] self._do_event(self.MOUSEEVENTF_MOVE + self.MOUSEEVENTF_ABSOLUTE, x, y, 0, 0) def press_button(self, pos=(-1, -1), button_name="left", button_up=False): """push a button of the mouse""" self.move_mouse(pos) self._do_event(self.get_button_value(button_name, button_up), 0, 0, 0, 0) def click(self, pos=(-1, -1), button_name= "left"): """Click at the specified placed""" self.move_mouse(pos) self._do_event(self._get_button_value(button_name, False)+self._get_button_value(button_name, True), 0, 0, 0, 0) def double_click (self, pos=(-1, -1), button_name="left"): """Double click at the specifed placed""" for i in xrange(2): self.click(pos, button_name) def get_position(self): """get mouse position""" return win32api.GetCursorPos() 

Here is a small example:

 import time mouse = Mouse() mouse.click((20, 10), "left") time.sleep(2.0) mouse.click((100, 100), "right") 

I hope this helps

This is from http://blog.lazynice.net/?p=63 .

The script every minute detects window inactivity. If inactivity exceeds 5 minutes, it simply sends a mouse event that moves the mouse a bit, so the splash screen may think that it is coming from the user, then reset the timer. Just set the idle time to less than the screen timeout, and then run it!

 from ctypes import Structure, windll, c_uint, sizeof, byref import time class LASTINPUTINFO(Structure): _fields_ = [('cbSize', c_uint), ('dwTime', c_uint)] def get_idle_duration(): lastInputInfo = LASTINPUTINFO() lastInputInfo.cbSize = sizeof(lastInputInfo) windll.user32.GetLastInputInfo(byref(lastInputInfo)) millis = windll.kernel32.GetTickCount() – lastInputInfo.dwTime return millis / 1000.0 while True: d = get_idle_duration() if d > 60 * 5: windll.user32.mouse_event(1, 1, 1, 0, 0) time.sleep(60)
