如何将自定义工具栏小部件添加到子窗体

Question

我有一个工具栏小部件，我希望它包含在所有数据表单中 由于QTDesigner不允许在designer中使用自定义小部件，所以我想在代码中添加它 上述数据表单将添加到主表单的MDI区域中 努力理解PyQT的工作原理

data_toolbar.py的代码如下

import sys

我想将其添加到下面的子表单代码中

from PyQt5 import QtCore, QtGui, QtWidgets

        self.label_2.setObjectName("label_2")
        self.lcdNumber = QtWidgets.QLCDNumber(DataForm)
        self.lcdNumber.setGeometry(QtCore.QRect(10, 50, 64, 23))
        self.lcdNumber.setObjectName("lcdNumber")
        self.pushButton = QtWidgets.QPushButton(DataForm)

        self.tb = QtWidgets.QWidget()
        self.tb.setGeometry(QtCore.QRect(0, 290, 577, 80))
        self.tb.setObjectName("tb")
        ui = Ui_FormToolBar("data_print", "n")
        ui.setupUi(self.tb)
        ui.reconfig(self)
        self.tb.show()
        self.retranslateUi(DataForm)
        QtCore.QMetaObject.connectSlotsByName(DataForm)

    def retranslateUi(self, DataForm):
        _translate = QtCore.QCoreApplication.translate
        DataForm.setWindowTitle(_translate("DataForm", "DataForm"))
        self.label_2.setText(_translate("DataForm", "TextLabel"))

        self.label.setText(_translate("DataForm", "TextLabel"))

似乎什么都不起作用，任何人都可以给出一个类似的例子或链接 实现同样目标的标准方法
