PyQt笔记002——页面代码分离

使用Qt Designer制作一个简单的ui页面
将ui界面个格式从.ui转为.py

ui界面的python代码

from PyQt5 import QtCore, QtGui, QtWidgetsclass Ui_MainWindow(object):    def setupUi(self, MainWindow):        MainWindow.setObjectName("MainWindow")        MainWindow.resize(497, 332)        self.centralwidget = QtWidgets.QWidget(MainWindow)        self.centralwidget.setObjectName("centralwidget")        self.pushButton = QtWidgets.QPushButton(self.centralwidget)        self.pushButton.setGeometry(QtCore.QRect(334, 210, 121, 61))        self.pushButton.setObjectName("pushButton")        MainWindow.setCentralWidget(self.centralwidget)        self.menubar = QtWidgets.QMenuBar(MainWindow)        self.menubar.setGeometry(QtCore.QRect(0, 0, 497, 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)        self.pushButton.clicked.connect(MainWindow.close)        QtCore.QMetaObject.connectSlotsByName(MainWindow)    def retranslateUi(self, MainWindow):        _translate = QtCore.QCoreApplication.translate        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))        self.pushButton.setText(_translate("MainWindow", "quit"))if __name__ == "__main__":    import sys    app=QtWidgets.QApplication(sys.argv)    widget = QtWidgets.QMainWindow()    ui=Ui_MainWindow()    ui.setupUi(widget)    widget.show()    sys.exit(app.exec_())

继承界面

from PyQt5 import QtWidgetsfrom simplewindow import Ui_MainWindowclass mywindow(QtWidgets.QMainWindow): # QtWidgets.+"继承的页面类型"     def __init__(self):        super(mywindow,self).__init__()        self.new = Ui_MainWindow()        self.new.setupUi(self)if __name__=="__main__":    import sys    app = QtWidgets.QApplication(sys.argv)    myshow = mywindow()    myshow.show()    sys.exit(app.exec())

直接继承界面

from PyQt5 import QtWidgetsfrom simplewindow import Ui_MainWindowclass mywindow(QtWidgets.QMainWindow, Ui_MainWindow):    def __init__(self):        super(mywindow,self).__init__()        self.setupUi(self)if __name__=="__main__":    import sys    app = QtWidgets.QApplication(sys.argv)    myshow = mywindow()    myshow.show()    sys.exit(app.exec_())
