pyqt5学习

首先贴出官方文档：https://www.riverbankcomputing.com/static/Docs/PyQt5/sip-classes.html

然后是github上的中文档：https://github.com/maicss/PyQt5-Chinese-tutorial

1 第一个PyQt5程序

1 利用pyqtdesign生成界面源码

利用pyqtdesign生成一个界面程序，然后将之转换为py源代码（这一步网上教程很多，略过）

2 从源码继承我们的逻辑类

CallFirstMainWin.py

from PyQt5.QtWidgets import QMainWindow
from CallFirstMainWin_ui import *


class MyMainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MyMainWindow, self).__init__(parent)
        self.setupUi(self)

3 写测试代码

main.py

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

import sys
from PyQt5.QtWidgets import QApplication
from CallFirstMainWin import MyMainWindow


if __name__ == "__main__":
    app = QApplication(sys.argv)
    myWin = MyMainWindow()
    myWin.show()
    sys.exit(app.exec_())

最后附上qtdesign工具生成转换得到的py文件 

CallFirstMainWin_ui.py

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

# Form implementation generated from reading ui file 'CallFirstMainWin_ui.ui'
#
# Created by: PyQt5 UI code generator 5.15.4
#
# WARNING: Any manual changes made to this file will be lost when pyuic5 is
# run again.  Do not edit this file unless you know what you are doing.


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")
        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", "MainWindow"))

运行界面：
