- 1、pyqtwebengine安装库
开发环境配置请参考博文：
【python】在pycharm中使用pyqt5进行gui开发的基本流程
1、pyqtwebengine安装库
加载网页需要使用pyqtwebengine库，可以使用import pyqt5.qtwebenginewidgets测试是否有这个库，如果没有，需要先安装
pip install pyqtwebengine -i https://pypi.douban.com/simple/
2、设计窗体
在qt designer里面，没有webengine窗体，只能在程序中创建，先将其他的部分放好。
这儿放置了一个lineedit，用于输入网址，一个按钮
3、生成代码
使用pyuic生成代码，生成的代码为：
# -*- 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, qtwidgets class ui_mainwindow(object): def setupui(self, mainwindow): mainwindow.setobjectname("mainwindow") mainwindow.resize(1200, 700) 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", "https://www.baidu.com")) self.pushbutton.settext(_translate("mainwindow", "打开"))
4、添加代码
引入库文件
from pyqt5 import qtcore, qtgui, qtwidgets,qtwebenginewidgets
1、添加webengine窗体
## 创建web窗体 self.qwebengine = qtwebenginewidgets.qwebengineview(mainwindow) self.qwebengine.setgeometry(20, 50, 1600, 600)
2、创建按钮功能
## 创建连接 self.pushbutton.clicked.connect(self.open_url)
3、编写按钮函数
def open_url(self): url=self.lineedit.text() self.qwebengine.load(qtcore.qurl(url))
4、添加启动程序
import sys if __name__ == '__main__': app = qtwidgets.qapplication(sys.argv) mainwindow = qtwidgets.qmainwindow() # 创建窗体对象 ui = ui_mainwindow() # 创建pyqt设计的窗体对象 ui.setupui(mainwindow) # 调用窗体的方法对对象进行初始化设置 mainwindow.show() # 显示窗体 sys.exit(app.exec_()) # 程序关闭时退出进程
