一、首先是主界面

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication
import Dialog1
import Dialog2
import sys


class Ui_Form(object): #這是用PyQt Designer生成的代碼，很簡單的，拖動(dòng)控件，生成ui文件，然后UIC轉(zhuǎn)換成py文件
  def setupUi(self, Form):
    Form.setObjectName("Form")
    Form.resize(440, 310)
    self.form = Form
    self.btn_d1 = QtWidgets.QPushButton(Form)
    self.btn_d1.setGeometry(QtCore.QRect(60, 140, 75, 23))
    self.btn_d1.setObjectName("btn_d1")

  def jump_to_demo1(self):    #這一塊注意，是重點(diǎn)從主界面跳轉(zhuǎn)到Demo1界面，主界面隱藏，如果關(guān)閉Demo界面，主界面進(jìn)程會(huì)觸發(fā)self.form.show()會(huì)再次顯示主界面

    ui = Dialog1.Ui_Dialog1()
    ui.setupUi(form1)

    self.pushButton = QtWidgets.QPushButton(Dialog2)
    self.pushButton.setGeometry(QtCore.QRect(140, 160, 75, 23))
    self.pushButton.setObjectName("pushButton")

    self.retranslateUi(Dialog2)
    QtCore.QMetaObject.connectSlotsByName(Dialog2)

  def retranslateUi(self, Dialog2):
    _translate = QtCore.QCoreApplication.translate
    Dialog2.setWindowTitle(_translate("Dialog2", "Dialog"))
    self.pushButton.setText(_translate("Dialog2", "Jump to main"))

  form = QtWidgets.QDialog()
  ui = Ui_Dialog2()
  ui.setupUi(form)
  form.show()
  sys.exit(app.exec_())
