python3.4 + pyqt5: Getting x,y out of QMouseEvent - python-3.4

Question

python3.4+pyqt5
I'm trying to write a program in which buttons shall create other buttons by dragging and press_releasing to form a representation of a rolling mill street.
I created a class Button which does the moving and handles several clicking events for the buttons in creation. This part is working fine.
Where I'm stuck is, I want to read the mouse position where these button should be created.
Here's the code:
def createConnects(self):
self.id000001.released.connect(self.do_something)
self.id000002.released.connect(self.do_something)
#QtCore.pyqtSlot()
def do_something(self):
self.bname = 'Button'
self.button = Button(self.bname, self)
posx = QtGui.QMouseEvent.x()
print(posx)
posy = QtGui.QMouseEvent.y
print(posy)
sender = self.sender()
print(str(sender.objectName()))
#self.button.move(posx, posy)
qmouseevent provides several functions, but the posx line gives me this error:
TypeError: QMouseEvent.x(): first argument of unbound method must have type 'QMouseEvent'
posy-line gives < built-in function y > which isn't what I want, too, but clear.
MouseTracking is switched on in MainWindow class.
Maybe, normaly one would do that by using event in the def line but since it's a slot, that would lead to other problems.
Any hints to get along?
Update:
As recommended here's the full code of the prototype:
#!/usr/bin/env python3.4
import sys, os, math, shutil, re
from subprocess import call, Popen
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.uic import loadUiType
Ui_MainWindow, QMainWindow = loadUiType('mainwindow.ui')
def main(argv):
app = QtWidgets.QApplication(argv)
mainwindow = MyMainWindow()
mainwindow.show()
sys.exit(app.exec_())
class Button(QtWidgets.QPushButton):
def __init__(self, title, parent):
super().__init__(title, parent)
self.button = QtWidgets.QPushButton()
def mouseMoveEvent(self, event):
if event.buttons() != QtCore.Qt.RightButton:
return
mimeData = QtCore.QMimeData()
drag = QtGui.QDrag(self)
drag.setMimeData(mimeData)
drag.setHotSpot(event.pos() - self.rect().topLeft())
dropAction = drag.exec_(QtCore.Qt.MoveAction)
def mousePressEvent(self, event):
QtWidgets.QPushButton.mousePressEvent(self, event)
if event.button() == QtCore.Qt.LeftButton:
print(event.button(),' pressed')
class MyMainWindow(QtWidgets.QMainWindow,Ui_MainWindow):
def __init__(self, *args):
QtWidgets.QMainWindow.__init__(self, *args)
self.setupUi(self)
self.setMouseTracking(True)
self.createConnects()
def dragEnterEvent(self, event):
event.accept()
def dropEvent(self, event):
position = event.pos()
self.button.move(position)
event.setDropAction(QtCore.Qt.MoveAction)
event.accept()
def createConnects(self):
self.id000001.released.connect(self.do_something)
self.id000002.released.connect(self.do_something)
#QtCore.pyqtSlot()
def do_something(self):
print('do_something')
self.bname = 'Button'
self.button = QtWidgets.QPushButton()
#self.button = Button(self.bname, self)
self.button.move(100, 65)
#posx = QtGui.QMouseEvent.x()
#print(posx)
#posy = QtGui.QMouseEvent.y
#print(posy)
sender = self.sender()
print(str(sender.objectName()))
#self.button.move(posx, posy)
if __name__ == '__main__':
main(sys.argv)
