How to use pyQT5 to display web pages

Editor to share with you how to use pyQT5 to display web pages, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. PyQTWebEngine installation Library

You need to use the PyQTWebEngine library to load the web page. You can use import PyQt5.QtWebEngineWidgets to test whether this library exists. If not, you need to install it first.

Pip install PyQtWebEngine-I https://pypi.douban.com/simple/2, Design form

In QT Designer, there is no WebEngine form, you can only create it in the program, put the rest of it away first.

3. Generate code

Using pyUIC to generate code, the generated code is:

#-*-coding: utf-8-*-# Form implementation generated from reading ui file 'web.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, QtWidgetsclass Ui_MainWindow (object): def setupUi (self, MainWindow): MainWindow.setObjectName ("MainWindow") MainWindow.resize (1200) self.centralwidget = QtWidgets.QWidget (MainWindow) self.centralwidget.setObjectName ("centralwidget") self.lineEdit = QtWidgets.QLineEdit (self.centralwidget) self.lineEdit.setGeometry (QtCore.QRect (20,10,631) 31) self.lineEdit.setObjectName ("lineEdit") self.pushButton = QtWidgets.QPushButton (self.centralwidget) self.pushButton.setGeometry (QtCore.QRect (690,10,90,30) self.pushButton.setObjectName ("pushButton") MainWindow.setCentralWidget (self.centralwidget) self.menubar = QtWidgets.QMenuBar (MainWindow) self.menubar.setGeometry (QtCore.QRect (0,0,1200) 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") self.lineEdit.setText (_ translate ("MainWindow", "http://www.baidu.com")) self.pushButton.setText (_ translate (" MainWindow "," Open ")) 4, add code

Import library files

From PyQt5 import QtCore, QtGui, QtWidgets,QtWebEngineWidgets

1. Add WebEngine forms

# # create web form self.qwebengine = QtWebEngineWidgets.QWebEngineView (MainWindow) self.qwebengine.setGeometry (20,50,600)

2. Create button function

# # creating a connection self.pushButton.clicked.connect (self.open_url)

3. Write button function

Def open_url (self): url=self.lineEdit.text () self.qwebengine.load (QtCore.QUrl (url))

4. Add a startup program

Import sysif _ _ name__ ='_ main__': app = QtWidgets.QApplication (sys.argv) MainWindow = QtWidgets.QMainWindow () # create a form object ui = Ui_MainWindow () # create a form object designed by PyQt ui.setupUi (MainWindow) # call the form method to initialize the object MainWindow.show () # display form sys.exit (app.exec_ ()) # exit the process when the program closes

5. Complete code
