   from PyQt4
import QtGui, QtCore

class MyWindow(QtGui.QWidget):
   def __init__(self, parent = None):
   super(MyWindow, self).__init__(parent)

self.pushButtonSimulate = QtGui.QPushButton(self)
self.pushButtonSimulate.setText("Simulate Mouse Release!")

self.layoutHorizontal = QtGui.QHBoxLayout(self)

def on_pushButtonSimulate_clicked(self):
   mouseReleaseEvent = QtGui.QMouseEvent(

QtCore.QCoreApplication.postEvent(self, mouseReleaseEvent)

def mouseReleaseEvent(self, event):
   if event.button() == QtCore.Qt.LeftButton:
   print "Mouse Release"

super(MyWindow, self).mouseReleaseEvent(event)

if __name__ == "__main__":
   import sys

app = QtGui.QApplication(sys.argv)

main = MyWindow()


You can use:

from PyQt4.QtTest
import QTest

#(...) Where you want to release
QTest.mouseRelease(widget_to_release, Qt.LeftButton)

This demonstrates how to control the mouse with Python. Using pynput we are able to simulate mouse events into any window. This will show you how to press buttons, scroll and move the mouse.,Make a variable called mouse and set it to an instance of Controller. Now using the mouse variable we can control the mouse.,To click buttons on the mouse, we would use Passing a button from the Button class imported and an integer, we can perform single, double and triple clicks for any button.,We will be using the pynput module to listen to mouse events. To install this module execute pip install pynput in cmd. Watch the output to make sure no errors have occurred; it will tell you when the module has been successfully installed.

from pynput.mouse
import Button, Controller
mouse = Controller()
print("Current position: " + str(mouse.position))
mouse.position = (10, 20)
mouse.move(20, -13)
# Click the left button, 1)
# Click the right button, 1)
# Click the middle button, 1)
# Double click the left button, 2)
# Click the left button ten times, 10)
