Python项目——久坐提醒定时器（PySide6）编写

1、介绍

• 使用Python编写一个久坐提醒软件。
• 功能：
  • 设置工作时间。
  • 设置休息时间。
  • 选择休息时是否播放音乐。
  • 休息时，软件置顶，且不能关闭。
  • 

2、工具

• 语言：python3.11
• UI设计工具：Qt designer
• 编译器：PyCharm
• 包：pygame、PySide6

3、代码

• 新建一个项目，准备好音乐。
  • 
• 使用Qt designer设计一个UI界面，保存ui文件，再转换为py文件并保存到项目目录中，供后续使用。
• 具体方法：Pyside6入门教学——编写一个UI界面并显示-CSDN博客
• 转换后的py文件如下：

4、展示

•  运行程序。
  • 
• 设置工作时间和休息时间，勾选播放音乐，点击开始。倒计时开始...
  • 
• 工作时间结束，播放音乐，开始休息倒计时。此时，窗口置顶，并且不能关闭，也不能点击开始。
  • 
• 休息时间结束，恢复窗口。此时可以关闭，也可以重新开始计时。
  •
