Почему не работают кнопки в диалоговом окне pyqt5?

Question

[renatakhabirova]

в первом файле создается основное окно

        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "Калькулятор физических величин"))
        self.label.setText(_translate("MainWindow", "Механика"))
        self.toolButton.setText(_translate("MainWindow", "Кинематика"))
        self.pushButton_2.setText(_translate("MainWindow", "Гидростатика"))
        self.pushButton_3.setText(_translate("MainWindow", "Динамика"))
        self.pushButton_4.setText(_translate("MainWindow", "Статика"))
        self.label_2.setText(_translate("MainWindow", "Термодинамика"))
        self.pushButton_5.setText(_translate("MainWindow", "Состояний"))
        self.pushButton_7.setText(_translate("MainWindow", "Процессов"))
        self.label_3.setText(_translate("MainWindow", "Оптика"))
        self.pushButton_6.setText(_translate("MainWindow", "Геометрическая"))
        self.pushButton_8.setText(_translate("MainWindow", "Волновая "))
        self.pushButton_9.setText(_translate("MainWindow", "Квантовая"))

во втором создается диалоговое окно, аналогично первому. при нажатии на кнопку вызываются функции.

self.pushButton.clicked.connect(self.ravnd)
        self.pushButton_2.clicked.connect(self.centr)
        self.pushButton_3.clicked.connect(self.prd)
        self.pushButton_4.clicked.connect(self.chst)

    def ravnd(self):  # функция, которая будет выполняться после нажатия кнопки
        a = self.lineEdit.text()
        b = self.lineEdit_2.text()
        c = int(a) / int(b)
        self.textEdit.append(str(c))

    def centr(self):
        a = self.lineEdit_7.text()
        b = self.lineEdit_8.text()
        c = int(a) ** 2 / int(b)
        self.textEdit_2.append(str(c))

    def prd(self):
        a = self.lineEdit_3.text()
        b = self.lineEdit_4.text()
        c = int(b) / int(a)
        self.textEdit_3.append(str(c))

    def chst(self):
        a = self.lineEdit_5.text()
        b = self.lineEdit_6.text()
        c = int(a) / int(b)
        self.textEdit_4.append(str(c))

в третьем "связываются" два окна, диалоговое вызывается по нажатию кнопки

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow, QDialog
import sys
from calcf import Ui_MainWindow
from kinematika import Ui_Dialog

app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()

def openkinem():
    global Dialog
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()

ui.toolButton.clicked.connect(openkinem)

sys.exit(app.exec_())

диалоговое окно появляется, но уже не работают кнопки в нем. но если запускать отдельно файл с диалоговым окном, то все работает

[Dimonchik]

маловато кода

[renatakhabirova]

Dimonchik, чего именно не хватает? просто ограничение стоит, поэтому второе окно полностью не вместила, импорты тоже

[Andrey]

Все плохо...

global Dialog
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()

Создаем QDialog и пихаем его в Ui которое уже диалоговое окно...
За global вам отдельное наказание надо придумать

По аналогии реализации нажатия на кнопку "Закрыть" реализуете и свои варианты событий
В целом конечно же надо вам заканчивать бездумно копировать код из инета и почитать чего-нибудь
