PyQt5 實現顯示和業務邏輯分離, 繼承主界面文件的主窗口類

環境

操作系統: Windows 10 專業版 64-bit (10.0, Build 16299) (16299.rs3_release.170928-1534)

Python Version: 3.7.1

PyQt5 Version: 5.11.3

Qt Designer Version: 5.11.2

界面代碼如下(firstMainWin.py)

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'firstMainWin.ui'

#

# Created by: PyQt5 UI code generator 5.11.3

#

# WARNING! All changes made in this file will be lost!

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):

def setupUi(self, MainWindow):

MainWindow.setObjectName("MainWindow")

MainWindow.resize(800, 600)

self.centralwidget = QtWidgets.QWidget(MainWindow)

self.centralwidget.setObjectName("centralwidget")

self.pushButton = QtWidgets.QPushButton(self.centralwidget)

self.pushButton.setGeometry(QtCore.QRect(220, 160, 141, 51))

self.pushButton.setObjectName("pushButton")

MainWindow.setCentralWidget(self.centralwidget)

self.menubar = QtWidgets.QMenuBar(MainWindow)

self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 23))

self.menubar.setObjectName("menubar")

MainWindow.setMenuBar(self.menubar)

self.statusbar = QtWidgets.QStatusBar(MainWindow)

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", "haha"))

self.pushButton.setText(_translate("MainWindow", "PushPush"))

主要邏輯代碼如下

import sys

from PyQt5.QtWidgets import QApplication, QMainWindow

from firstMainWin import *

class MyMainWindow(QMainWindow, Ui_MainWindow):

def __init__(self, parent=None):

super(MyMainWindow, self).__init__(parent)

self.setupUi(self)

if __name__ == "__main__":

app = QApplication(sys.argv)

myWin = MyMainWindow()

myWin.show()

sys.exit(app.exec_())

運行后顯示效果如下圖
