my GUI screen is freeze and having issue for passing the value from 2nd window to 1st window (Pyqt5)

Below are the 2 window codes, 1st is main window and 2nd is widget window:

Below are 2nd window:

submit_execute_thread.start()
self.check_execute_thread()
def check_execute_thread(self):
if submit_execute_thread.isRunning() == True:
time.sleep(10)
self.check_execute_thread()
else:
Form.close()
def ok_execute(self):
if self.checkBox_1.isChecked() and self.checkBox_2.ischecked():
self.list_result = ["a","b","c","d","e"]
i have 2 issue here:
My objective is click the File --> Open and 2nd window appear, when i tick the checkbox1 and checkbox2 and press ok_button, i connect the ok_button to OK_thread and make a Qthread to ok_execute function to prevent freezing while running the function and keep checking the thread every 10 seconds until it run finish and close the Form window. I am not sure what is the issue here as it could not work, my GUI still freezing after i press OK_button and never run finish.
passing value:
i try to define the list = [] in def init() in both main window and 2nd window but some variable become not declarable such as "Form", so when i open the Form window from main window, it could not work. and another issue is how do i pass the value from Form window which is from ok_execute return self.list_result to Mainwindow, so when i click the result button in Main Window, it will show the list_result in the listview widget.
Please help me modify the code and appreciate your help.
Thank you.

document.print_(printer) is very convenient but it is not a little flexible.
Because you don't use QTextEdit, you must edit the format information by your code only. (except for setHtml in advance.)
If you draw QPrinter document as you like, you can use QPainter.
Normarly, although QPainter is used in paintEvent(self, event), only if you set a subclass of QPaintDevice to constructor of QPainter, you can draw as you like.
But you must calculate the allocation exactly.
QPrinter is a subclass of QPaintDevice.
Trap
The topleft of QPainter.drawText is the bottom line of Text.
(x, y)→ MY TEXT
Here is the code.
# -*- coding: utf-8 -*-

documentRootFrameFormat = document.rootFrame().frameFormat()
documentLeftMargin = documentRootFrameFormat.leftMargin()
documentTopMargin = documentRootFrameFormat.topMargin()
drawn_im = QtGui.QImage("logo4.jpg")
drawn_im_height = drawn_im.height()
painter = QtGui.QPainter(printer)
painter.drawImage(documentLeftMargin, documentTopMargin, drawn_im)
painter_font = painter.font()
#you can set flag which font is used.
custom_font = QtGui.QFont("Segoe UI Light", 18)

painter.save()
painter.setFont(custom_font)

My Result
If you want to use QTextCursor, you can set Font & format by using the method of QTextCursor.
You can get the similar result by this code.
I recommend this if you don't hope high control.

I used this code too which is present in official documentation.

playlist.setCurrentIndex(1)
player.play()
while using this code which is in official documentation. this error occurred.

As the error and the docs point out, a QMediaContent must be passed to the addMedia method. To build a QMediaContent you can use a QUrl:

How to pass variable through different windows in PyQt5?

I have two windows, first window is 'FirstWindow' and second is 'Calendar'. first window has one push button (pbSelectDate) and one label (lbDate). calendar window has calendar (CalendarBox) and one push button (pbSelect).
when i click select (pbSelectDate) from first window, calendar window pops up. I select the date and press select button (pbSelect) in the calendar window. i want to print the selected date to the label (lbDate) in the first window.
thanks in advance. :)

Do not modify the code generated by Qt Designer but create another class that inherits from the appropriate widget and use the initial class to fill it.
QLabel.setText(const QString )
Setting the text clears any previous content.

Show and hide\close windows with user arguments using PyQt5

I am writing GUI app with the help of Qt Designer. The app consists of multiple windows, so when the user clicks the push button on one window, the next window should open and the current window should hide. I achieved this feature for going from window 1 to window 2. But I am not able to do this to move from window 2 to window 3. I think this might be because the window 2 gets user arguments.
Is there any way to hide the window which gets user arguments?
The code is as follows:
Class for main window:
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
import user_data
class MainWindow(object):
def user_data(self):
self.user_data_window = QtWidgets.QMainWindow()
self.next_window = user_data.Ui_UserData()
self.next_window.setupUi(self.user_data_window)
main_window.hide()
self.user_data_window.show()
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(640, 480)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(140, 100, 361, 81))
font = QtGui.QFont()
font.setPointSize(24)
font.setBold(True)
font.setWeight(75)
self.label.setFont(font)
self.label.setObjectName("label")
