PyQt5 - 鼠标连点器

⭐️前言

本次设计的鼠标连点器主要是对QVBoxLayout、QHBoxLayout和QStackedWidget进行一个回顾复习，加深对它们的理解，提高运用的熟练度。

⭐️鼠标连点器

如以下代码所示，设计两个QWidget控件，分别为QWidget1和QWidget2，QWidget1中设计的是连点器基本设计窗口，可输入鼠标的点击速度和点击总时长；QWidget2中设计的是连点器执行后的窗口，其中有倒计时准备和执行过程的窗口显示。

    liandianqi.show()
    sys.exit(app.exec_())

运行结果：

• 写一个窗口测试点击，点击“开始点击”按钮前
  
• 点击“开始点击”按钮后进入5秒倒计时
  
• 开始点击。进入设置的3秒点击时长，0.01秒/次的点击速度。鼠标每点击“点击”按钮一次，就会在控制台打印被点击。
