Dynamically insert checkboxes into a tabWidget

Question

I am building a small application using pyQt5. Till now I've built a UI using QtCreator, converted that to a Python file using pyuic and now on the push of a button, it should dynamically populate the tabWidget's tabs with checkboxes having labels pulled from a string list. I can't seem to figure out the best way to go about this problem.

Till now I've done the following.

1. Link the UI file with my main python code.
2. Handle a button click to call a function to insert checkboxes.

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.auth_select.clicked.connect(self.handle_auth)
        self.show()
    def populate_tabs(self):
        self.tabWidget.addWidget(QtWidgets.QCheckBox())

I cannot seem to figure out how to dynamically insert the checkboxes into a certain tab. Let's say my tab name is main_tab; I want to insert 5 checkboxes whose labels and ids come from 2 lists labels[] and ids[].

Answer 1

Alright, for anyone who stumbles upon this. I went about this as described below.

1. Create a layout to house inner elements
2. Dynamically insert QWidgets into this layout
3. Finally set the layout of the tab/widget you need to, to the above.

A small example is [extended from above]

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.auth_select.clicked.connect(self.handle_auth)
        self.show()
        self.populate_tabs(connection_string)
    def populate_tabs(self, connection_string):
        layout = QGridLayout()
        for i in range(1, 5):
            for j in range(1, 10):  
                layout.addWidget(QCheckBox("Check #{}".format(i)) , i, j)

        self.tabWidget.widget(2).setLayout(layout)
