PyQt5说明
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http://www.riverbankcomputing.co.uk/news。
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。
pyqt5的类别分为几个模块,包括以下:
- QtCore:包含了核心的非GUI功能。此模块用于处理时间、文件和目录、各种数据类型、流、URL、MIME类型、线程或进程。
- QtGui:包含类窗口系统集成、事件处理、二维图形、基本成像、字体和文本。
- QtWidgets:包含创造经典桌面风格的用户界面提供了一套UI元素的类。
- QtMultimedia:包含的类来处理多媒体内容和API来访问相机和收音机的功能。
- QtBluetooth:包含类的扫描设备和连接并与他们互动。描述模块包含了网络编程的类。这些类便于TCP和IP和UDP客户端和服务器的编码,使网络编程更容易和更便携。
- QtNetwork
- QtPositioning:包含类的利用各种可能的来源,确定位置,包括卫星、Wi-Fi、或一个文本文件。
- Enginio:模块实现了客户端库访问Qt云服务托管的应用程序运行时。
- QtWebSockets:包含实现WebSocket协议类。
- QtWebKit:包含一个基于Webkit2图书馆Web浏览器实现类。
- QtWebKitWidgets:包含的类的基础webkit1一用于qtwidgets应用Web浏览器的实现。
- QtXml:包含与XML文件的类。这个模块为SAX和DOM API提供了实现。
- QtSvg:提供了显示SVG文件内容的类。可伸缩矢量图形(SVG)是一种描述二维图形和图形应用的语言。
- QtSql:提供操作数据库的类。
- QtTest:包含测试的功能,使pyqt5应用程序的单元测试
PyQt4和PyQt5的区别
pyqt5不向后兼容pyqt4。pyqt5有几个显著的变化。将旧代码调整到新库并不困难。有几个大的改变如下:
- Python模块已经重组。一些模块已经删除(qtscript),有的被分割成子模块(QtGui,QtWebKit)。
- 新的模块作了详细的介绍,包括qtbluetooth,qtpositioning,或enginio。
- pyqt5只支持新型的信号和槽handlig。电话signal()或slot()不再支持。
- pyqt5不支持Qt的API被标记为过时或陈旧的任何部分在QT V5.0。
Demo
本人曾写过一个数字货币搬砖的界面,效果如下图:
界面的设计用的是pyqt5,设计完成后使用命令 python -m PyQt5.uic.pyuic xxx.ui -o xxx.py 转换为python的代码
转换后的代码:
