前言
本文给大家分享的是如何通过用PyQt5制作小型桌面应用
PyQt概述
PyQt5是Qt框架的Python/ target=_blank class=infotextkey>Python语言实现,由Riverbank Computing开发,是最强大的GUI库之一。PyQt提供了一个设计良好的窗口控件集合,每一个PyQt控件都对应一个Qt控件,因此PyQt的API接口与Qt的API接口很接近,但PyQt不再使用QMake系统和Q_OBJECT宏。
PyQt5可以做这些桌面程序。
准备了Python 编写的 15 个小型桌面应用程序
桌面应用程序
开发工具
Python版本:3.7
相关模块:
socket模块
time模块
sys模块
threading模块
PyQt5模块
环境搭建
安装Python并添加到环境变量,pip安装需要的相关模块即可。
Conda环境
建议安装anaconda集成环境,简称conda环境, 内部默认安装数据分析(Numpy/Pandas)、爬虫Scrapy框架、Web框架、PyQt等相关工具。

在 bin目录下,存在一个Designer.app应用是PyQt的Designer设计器。文件的扩展名是.ui。
因为Conda安装之后,默认是base环境,所以可以使用Coda命令创建新的开发环境:
conda create -n gui python=python3.7
激活环境
conda activate gui
安装pyqt5
(gui) > pip install pyqt5==5.10
如果安装的PyQt5版本高于5.10,部分库将要单独安装,如WebEngine
(gui) > pip install PyQtWebEngine
PyQt5+Socket实现中心化网络服务
