Ubuntu下PyQt5使用总结_ubuntu pyqt5

       因为工作中需要给交付团队开发桌面工具，考虑到交付团队多使用Mac，调研了一下发现PyQt5可以实现跨平台，满足工具开发需要，就用其开发了桌面工具。现以ubuntu开发环境为例总结一下开发过程。

目录

1.安装python3.7

2.安装PyQt5版本5.15.2

3.protobuf库使用

4.编写pyqt5程序

4.1设计界面并产生py代码

 4.2封装mainwindow.py成MainWidget.py

4.3调用MainWidget.py

5.打包

 i. 安装pyinstaller

ii. 打包

---

1.安装python3.7

sudo apt-get install python3.7

2.安装PyQt5版本5.15.2

sudo pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple/ pyqt5==5.15.2
另外一种安装方法：
sudo pip3 install PyQt5==5.15.2

3.protobuf库使用

i. 查看版本
sudo pip3 index versions protobuf
ii. 卸载
 sudo pip3 uninstall protobuf
iii. 安装指定版本
sudo pip3 install protobuf==3.19.0

4.编写pyqt5程序

4.1设计界面并产生py代码

i. 安装Qt Designer并使用其设计界面
例如得到界面文件mainwindow.ui

ii. .ui文件转.py文件
python3 -m PyQt5.uic.pyuic -o mainwindow.py mainwindow.ui

 4.2封装mainwindow.py成MainWidget.py

mainwindow.ui

4.3调用MainWidget.py

项目目录结构如下：

main.py

"""
This is the main module.
"""
#coding=utf-8
from PyQt5 import QtCore, QtGui, QtWidgets
from MainWidget import MainWidget
import sys
 
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    main_widget = MainWidget()#QtWidgets.QMainWindow()
    main_widget.setWindowTitle("version: " + "1.0.0.1")
    main_widget.show()
    deskRect = QtWidgets.QApplication.desktop().screenGeometry()
    x = deskRect.width() / 12
    y = deskRect.height() / 12
    main_widget.move(x, y)
    main_widget.resize(deskRect.right() - 2 * x, deskRect.bottom() - 2 * y)
    sys.exit(app.exec_())

运行结果如下：

python3 main.py

 

5.打包

 i. 安装pyinstaller

sudo pip3 install pyinstaller

ii. 打包

pyinstaller -i tool.ico -w main.py

tar -zcvf  anptools_v1.0.0.10.tar.gz dist

dist/main目录下的main即可运行
