pyqt5简单使用记录

2024-02-13 11:36:16

背景：有个比较小需求经常要帮客户处理，所以学了下pyqt5,打算做一个图形化的界面，打包成exe提供给客户自己使用

学习主要参考以下：
https://zmister.com/archives/169.html
https://github.com/maicss/PyQt5-Chinese-tutorial/blob/master/SUMMARY.md

. 首先使用图形化工具pyqt5designer.exe画出界面，接下来是一个小demo
具体可参考上面的博客学习，如果没有可手动安装，pip install pyqt5-tools
. 保存界面会生成.ui文件，通过命令pyuic5 -o test.py test.ui会生成一个test.py的python文件，打开.py脚本可以看到代码，手动运行发现界面和设计的一致，加了一些简单的交互代码，点击注册会显示上面控件的结果，如果选择中不为空，则以自身为准，若选择为空，则显示性别的结果
. 直接上所有代码，仅供参考：

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    qt = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(qt)
    ui.pushButton.clicked.connect(click_button)
    qt.show()
    sys.exit(app.exec_())

安装pyinstaller,pip install pyinstaller，使用pyinstaller -F test.py打包，会生成一个test.exe的文件
pyinstaller使用参考https://blog.csdn.net/yufen9987/article/details/73865281
