Pyqt5 Stop Function with Stop Button - python

We control our process with variables like "self.runHunt". If we get the "True" value, we start the time and print our text. When we press stop, we tell it to take the value "false" and stop the process. I think there is no problem here.
But;
Time starts when our function is "while true". At that time, even if we press the stop button, time continues and our value still remains as "True" and cannot update itself. However, after the time expires, the value becomes "false".
My question is how can I get the "false" variable without waiting for the time to complete?

PyQt5 QPushbutton to store ariables Python

Using PyQt5 QPlaintext to store variables. Example AO = userinput?
What I have so far minus the GUI setup. I need to store it as simple variables so i can output to a DOCX. I know I have to manually user input for every QPlaintextbox available. would I use the getText(), link it to the push button to generate the variables. Thank you for your time.

as I see on your code, to get string from the QLineEdit you can use this code.
self.num.text()
if you print that code, it will automatically print the inputed string of QLineEdit.
you can add a QPushButton then make a signal slot to do that as a form in commonly use.
like these:
self.button = QPushButton()
self.button.clicked.connect(self.getLineEdit)
def getLineEdit(self):
lineEditText = self.num.text()
print(lineEditText)

I just need to be able to pull the results from the input that has been entered, if the frames are enabled(checked) when I click the submit buttons. Output should be true or false for checkboxes and radio buttons and integers, a double, and a string for the rest. I'm sure I'm missing something simple.

We created a class MainWindow for the top-level window.
Create an instance of it and display the widget on the screen.
w = MainWindow()
w.show()
Added the ability to get the selected item in the QComboBox drop-down list.
Corrected the output format in the on_clicked method.

How to show the live preview from picamera in a GUI Window made by PyQt5?

I am designing a GUI to capture an image from picamera, I am using PyQt5 to develop the GUI. I used camera.start_preview() function to see the live preview. After that I used a button named "Take" to capture the image and after capturing the image I showed the image in Qlabel by using self.label_2.setPixmap(QtGui.QPixmap()) command till this my code is working fine. Now I want to set the live preview of PiCamera into the same Qlabel, which I am using to show the captured image. Is it possible to set the live preview inside a QLabel?
After googling I found PIL can be used to stream live preview inside an window, but I have no idea how to implement it.

Getting an error while trying to close and open current dialog window in python
I need to open and close two windows in loop.
also attaching the error that i got.
enter image description here

The reason of the error is that Dialog is not available in scope of loginCheck method and need to be passed explicitly as a param in the following line:
self.pbtn_signin.clicked.connect(self.loginCheck)
Here is the question with the answers, how to do it.
One of the options would be import partial from functools:
from functools import partial
And use this function to pass Dialog to loginCheck:
self.pbtn_signin.clicked.connect(partial(self.loginCheck, Dialog))
