python3GUI--浏览器By:PyQt5（附源码）

---

时隔一个月，使用PyQt5开发了一款浏览器，不但能满足日常网页浏览，还支持一些辅助功能，例如：截图、收藏网址、查看浏览历史、主题颜色设置…来吧~

一．准备工作

1.PyQt5

pyqt5是一套Python绑定Digia QT5应用的框架。它可用于Python 2和3。本教程使用Python 3。Qt库是最强大的GUI库之一。pyqt5的官方网站https://doc.qt.io/qtforpython-5/。
pyqt5做为Python的一个模块，它有620多个类和6000个函数和方法。这是一个跨平台的工具包，它可以运行在所有主要的操作系统，包括UNIX，Windows，Mac OS。pyqt5是双重许可。开发者可以在GPL和商业许可之间进行选择。安装：

pip install PyQt5

PyQt5官方文档：

https://doc.qt.io/qtforpython-5

2.Qwebengineview

pyqt5 已经抛弃 QtWebKit和QtWebKitWidgets，而使用最新的QtWebEngineWidgets。QtWebEngineWidgets，是基于chrome浏览器内核引擎的。安装：

pip install PyQtWebEngine

QWebEngineView官方文档：

https://doc.qt.io/qtforpython-5/PySide2/QtWebEngineWidgets/QWebEngineView.html

3.PyQt5-tools

PyQt5-tools里面包含了一系列QT开发的GUI工具，能有效减少代码量。

在PyQt中编写UI界面可以直接通过代码来实现，也可以通过Qt Designer来完成。Qt Designer的设计符合MVC的架构，其实现了视图和逻辑的分离，从而实现了开发的便捷。Qt Designer中的操作方式十分灵活，其通过拖拽的方式放置控件可以随时查看控件效果。Qt Designer生成的.ui文件（实质上是XML格式的文件）也可以通过pyuic5工具转换成.py文件。
Qt Designer随PyQt5-tools包一起安装，其安装路径在 “Python安装路径\Lib\site-packages\pyqt5-tools”下。
若要启动Qt Designer可以直接到上述目录下，双击designer.exe打开Qt Designer；或将上述路径加入环境变量，在命令行输入designer打开；或在PyCharm中将其配置为外部工具打开。

二．功能展示

1.主页

浏览器启动后，会自动打开设定好的网页。

2.我的收藏

通过读取本地指定txt文件，显示收藏的链接。

3.浏览历史

此界面记录所有本次浏览历史记录。

4.网页截图

通过调用自带的API实现网页截图。

5.收藏

点击收藏，将网页收藏到我的收藏。

6.复制链接

复制当前浏览器网页链接地址到剪切板。

7.网页放大/缩小

通过点击工具栏按钮和设置中的组合栏对浏览器网页进行缩放操作，同时显示当前浏览器放大比例。

8.设置-基本

在基本设置中可以设置主页、搜索引擎、网页缩放比例。

9.设置-个性

在个性设置中，可以设置主题颜色、UA、语言等。

10.设置-隐私

在隐私设置中，可以清理浏览历史记录、cookie、设置文件下载路径、截图保存路径

三．界面设计

1.主窗口设计

2.设置窗口设计

1.设置-基本

2.设置-个性
3.设置-隐私

3.整体QSS设计

使用QSS，设置浏览器整体颜色风格，设置控件边框颜色、边框角度等视觉展示效果，首次启动默认使用此颜色作为主题颜色。

五．总结

本次使用PyQt5制作了一款浏览器，基本实现了一般浏览器的功能，不过还是存在一些不足，例如：
1.所有网页跳转均在主窗口中进行，不支持多页显示和操作
2.不支持视频播放
3.设置里面的部分内容没有实现，比如：语言切换
4.网页收藏格式过于简单，只是文本文件操作，可以使用html格式，便于规范

---

在此，提出我的解决问题方案：
1.PyQt5中使用QTabwidget标签页，网页跳转时，创建新的标签页。可参考：

python PyQt QtWebEngine实现本窗口跳转+ 新窗口跳转

2.重新编译QtWebEngine。可参考：

解决QtWebEngine无法播放H5中的mp4

3.使用QtLinguist，逐个翻译。可参考：

PyQt5 pycharm配置(2)语言家QtLinguist

4.这个简单，使用Python自带的字符串处理函数，将title放在a标签里，将链接地址放在href中，最后存为.html格式
程序打包好放在了百度云中（密码：8888），欢迎各位使用、测试。思路、代码方面有什么不足欢迎各位大佬指正、批评！能点个赞给我个鼓励吗？

六．附录：开发记录

2021-10-10
1.设计UI界面，用浏览器填充整个窗口，设计菜单栏、工具栏
2.绑定浏览器事件以及对应函数
    （1）urlChanged：->show_jump_url(url)  展示“加载”进度条、将URL显示在输入框中
    （2）loadProgress：->show_load_progress(progress)  显示加载进度，设置窗口标题
    （3）loadFinished:->change_history_state()  改变“前进”，“后退”按钮状态
    （4）iconChanged：->lambda icon:self.setWindowIcon(icon)    设置窗口图标

2021-10-18
1.输入时，判断输入类型，根据输入类型改变按钮标题为“转到”或“搜索” textEdited：->judge_input(text)
2.尝试调用X度搜索建议，但是界面会闪退

2021-10-19
1.历史记录URL、title，绑定双击事件、清理缓存
2.收藏记录
