Python w/QT Creator form - Possible to grab multiple values? - forms

Question

I'm surprised to not find a previous question about this, but I did give an honest try before posting.
I've created a ui with Qt Creator which contains quite a few QtWidgets of type QLineEdit, QTextEdit, and QCheckbox. I've used pyuic5 to convert to a .py file for use in a small python app. I've successfully got the form connected and working, but this is my first time using python with forms.
I'm searching to see if there is a built-in function or object that would allow me to pull the ObjectNames and Values of all widgets contained within the GUI form and store them in a dictionary with associated keys:values, because I need to send off the information for post-processing.
I guess something like this would work manually:
...
dict = []
dict['checkboxName1'] = self.checkboxName1.isChecked()
dict['checkboxName2'] = self.checkboxName2.isChecked()
dict['checkboxName3'] = self.checkboxName3.isChecked()
dict['checkboxName4'] = self.checkboxName4.isChecked()
dict['lineEditName1'] = self.lineEditName1.text()
... and on and on
But is there a way to grab all the objects and loop through them, even if each different type (i.e. checkboxes, lineedits, etc) needs to be done separately?
I hope I've explained that clearly.
Thank you.

Finally got it working. Couldn't find a python specific example anywhere, so through trial and error this worked perfectly. I'm including the entire working code of a .py file that can generate a list of all QCheckBox objectNames on a properly referenced form.
I named my form main_form.ui from within Qt Creator. I then converted it into a .py file with pyuic5
pyuic5 main_form.ui -o main_form.py
This is the contents of a sandbox.py file:
from PyQt5 import QtCore, QtGui, QtWidgets
import sys
import main_form
# the name of my Qt Creator .ui form converted to main_form.py with pyuic5
# pyuic5 original_form_name_in_creator.ui -o main_form.py
class MainApp(QtWidgets.QMainWindow, main_form.Ui_MainWindow):
def __init__(self):
super(self.__class__, self).__init__()
self.setupUi(self)
# Push button object on main_form named btn_test
self.btn_test.clicked.connect(self.runTest)
def runTest(self):
# I believe this creates a List of all QCheckBox objects on entire UI page
c = self.findChildren(QtWidgets.QCheckBox)
# This is just to show how to access objectName property as an example
for box in c:
print(box.objectName())
def main():
app = QtWidgets.QApplication(sys.argv) # A new instance of QApplication
form = MainApp() # We set the form to be our ExampleApp (design)
form.show() # Show the form
app.exec_() # and execute the app
if __name__ == '__main__': # if we're running file directly and not importing it
main() # run the main function

See QObject::findChildren()
In C++ the template argument would allow one to specify which type of widget to retrieve, e.g. to just retrieve the QLineEdit objects, but I don't know if or how that is mapped into Python.
Might need to retrieve all types and then switch handling while iterating over the resulting list.
