QThread does not Wait()

[Demosthenes Koptsis]

Hello, i test Qthread and i made an example with a Form, Run, Stop 
buttons and a progressbar.

I want to click Run button and start a thread and to click Stop button 
and Wait the thread.

I try to implement a movetothread example but the wait fails.

Here is the code.

MainWindow.py

     def setupUi(self, Form):
         Form.setObjectName("Form")
         Form.resize(400, 138)
         self.btnRun = QtWidgets.QPushButton(Form)
         self.btnRun.setGeometry(QtCore.QRect(20, 20, 89, 25))

         self.btnStop.setGeometry(QtCore.QRect(20, 60, 89, 25))
         self.btnStop.setObjectName("btnStop")
         self.progressBar = QtWidgets.QProgressBar(Form)
         self.progressBar.setGeometry(QtCore.QRect(20, 100, 371, 23))
         self.progressBar.setProperty("value", 24)
         self.progressBar.setObjectName("progressBar")
         self.dial = QtWidgets.QDial(Form)
         self.dial.setGeometry(QtCore.QRect(200, 20, 50, 64))
         self.dial.setObjectName("dial")
         self.lcdNumber = QtWidgets.QLCDNumber(Form)
         self.lcdNumber.setGeometry(QtCore.QRect(260, 20, 64, 71))
         self.lcdNumber.setObjectName("lcdNumber")

         self.retranslateUi(Form)
         QtCore.QMetaObject.connectSlotsByName(Form)

     def retranslateUi(self, Form):
         _translate = QtCore.QCoreApplication.translate
         Form.setWindowTitle(_translate("Form", "Test Thread"))
         self.btnRun.setText(_translate("Form", "Run"))
         self.btnStop.setText(_translate("Form", "Stop"))

When i call WaitThread the emit of counter stops but the while loop 
works after all
