Не отображается динамически созданный элемент Qlabel в QFrame

Question

При добавлении QLabel в QFrame элемент не отображается в нем, но создается.

Если изначально создать объект QLabel в конструкторе класса и при нажатии на QButton последний отобразится, но изначально будет создан в QFrame, но будет невидимым (что не нужно).

Как динамически создавать один и тот же QLabel в QFrame чтобы изначально QFrame не имел дочерних элементов, а они появлялись в нем только после нажатия на кнопку.

class Ui_MainWindow(object):
def __init__(self):
    self._translate = QtCore.QCoreApplication.translate

def setupUi(self, MainWindow):
    MainWindow.setObjectName("MainWindow")
    MainWindow.resize(1000, 600)
    self.centralwidget = QtWidgets.QWidget(MainWindow)
    self.centralwidget.setObjectName("centralwidget")
    self.gridLayout = QtWidgets.QGridLayout(self.centralwidget)
    self.gridLayout.setObjectName("gridLayout")
    self.widget = QtWidgets.QWidget(self.centralwidget)
    self.widget.setObjectName("widget")
    self.gridLayout_2 = QtWidgets.QGridLayout(self.widget)
    self.gridLayout_2.setObjectName("gridLayout_2")

    self.frame = QtWidgets.QFrame(self.widget)
    self.frame.setFrameShape(QtWidgets.QFrame.StyledPanel)
    self.frame.setFrameShadow(QtWidgets.QFrame.Raised)
    self.frame.setObjectName("frame")


    self.gridLayout_2.addWidget(self.frame, 0, 0, 1, 1)
    self.gridLayout.addWidget(self.widget, 0, 0, 1, 1)

    self.widget_2 = QtWidgets.QWidget(self.centralwidget)
    self.widget_2.setObjectName("widget_2")

    self.pushButton = QtWidgets.QPushButton(self.widget_2)
    self.pushButton.setGeometry(QtCore.QRect(30, 30, 113, 32))
    self.pushButton.setObjectName("pushButton")
    self.pushButton.clicked.connect(self.addLabel)
    self.gridLayout.addWidget(self.widget_2, 0, 1, 1, 1)
    MainWindow.setCentralWidget(self.centralwidget)

    MainWindow.setMenuBar(self.menubar)
    self.statusbar = QtWidgets.QStatusBar(MainWindow)
    self.statusbar.setObjectName("statusbar")
    MainWindow.setStatusBar(self.statusbar)

def retranslateUi(self, MainWindow):
    MainWindow.setWindowTitle(self._translate("MainWindow", "MainWindow"))
    self.pushButton.setText(self._translate("MainWindow", "PushButton"))

    self.label.setObjectName("label")
    self.label.setText(self._translate("MainWindow", "TextLabel"))
    print(self.frame.children())

Не уверен что правильно понимаю вас, но я увидел вашу задачу так:

Update

мне нужно нажатием по кнопке плодить Qlabel, а не переопределять старый объект. Что бы при каждом нажатии создавался + еще один объект. 1,2,3,4,5...
