一. 演示效果
二. 准备工作
1. 使用pip 下载所需包 pyqt5
2. 下载可视化UI工具 QT Designer
链接:https://pan.baidu.com/s/1ic4S3ocEF90Y4L1GqYHPPA?pwd=ywct
提取码:ywct
3. 可视化UI工具汉化
把上面的链接打开, 里面有安装和汉化包, 前面的路径还要看你安装在哪里, 然后把汉化包直接放到这个文件夹中就可以了
4. pycharm配置QT Designer
Arguments: -m PyQt5.uic.pyuic FileName -o FileNameWithoutExtension.py
QT Designer作用: 快速打开QT Designer布局工具PyUIC作用: .ui布局文件转成.py布局文件, 也就是test.ui -> test.py
三. 代码
1. 文件结构
2. 代码
test.ui

四. 打包- pyinstaller
说明: 桌面软件开发完毕之后, 需要打包成.exe文件, 这样才能分发给其他人使用
下载好之后, 把pyinstaller配置到电脑的PATH中, 这样就可以使用cmd执行了
打包后的样子
完毕!!! 希望可以让刚开始学的小伙伴增加点思路~
