Как динамически изменять размеры QLineEdit в сетке QGridLayput?

Question

[kapit]

При демонстрации QLineEdit разрушает все построение QGridLayput, а хотелось бы чтобы QLineEdit вел себя так же как QLabel. Как этого добиться?

class winShow(QtWidgets.QWidget):
	def __init__(self):
		super(winShow, self).__init__()
		self.allotted = list()
		self.dict_widgets = dict()
		self.create_grid()

	def create_grid(self):
		self.layout = QtWidgets.QVBoxLayout()
		self.gridbox = QtWidgets.QGridLayout()
		n = ['name_label_{}'.format(str(x)) for x in range(9)]
		ne = ['name_edit_{}'.format(str(x)) for x in range(9)]
		t = ['12', '13', '14', '34', '10', '54', '67', '43', '34']
		p = [(i,j) for i in range(3) for j in range(3)]

		for name, text, position in zip(n, t, p):
			self.dict_widgets[name] = QtWidgets.QLabel(text)
			self.gridbox.addWidget(self.dict_widgets[name], *position)
			self.dict_widgets[name].setObjectName(name)
			self.allotted.append(name)

		for name, text, position in zip(ne, t, p):
			self.dict_widgets[name] = QtWidgets.QLineEdit(text)
			self.gridbox.addWidget(self.dict_widgets[name], *position)
			self.dict_widgets[name].hide()

		self.layout.addLayout(self.gridbox)
		self.layout.addStretch(10)
		self.setLayout(self.layout)
		qApp.installEventFilter(self)

	def eventFilter(self, obj, event):
		if event.type() == QEvent.MouseButtonPress:
			if obj.objectName() in self.allotted:
				name = obj.objectName()
				for widget in self.dict_widgets:
					if 'edit' in widget: 
						self.dict_widgets[widget].hide()
					elif 'label' in widget: 
						self.dict_widgets[widget].show()
				nl = name.split('_')
				self.dict_widgets[name].hide()
				self.dict_widgets['{}_edit_{}'.format(nl[0], nl[2])].show()

		return QWidget.eventFilter(self,obj,event)

if __name__ == '__main__':
	app = QtWidgets.QApplication(sys.argv)
	window = winShow()
	window.resize(200, 50)
	window.show()
	sys.exit(app.exec_())

Лучше, конечно, использовать нормальную таблицу, например, QTreeWidget.
Но можно так:

class MineLineEdit(QtWidgets.QLineEdit):
  def __init__(self, text, parent=None):
    super().__init__(text, parent)
    self.setSizePolicy(QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Preferred, QtWidgets.QSizePolicy.Preferred))
    self.parent = parent

  def sizeHint(self):
    if not self.parent:
      return super().sizeHint()
    print(self.parent.size())
    return self.parent.size()

<...>

      self.dict_widgets[name] = MineLineEdit(text, self.dict_widgets[name.replace('edit', 'label')])
