PyQt5 QCommandLinkButton – 设置自动重复间隔时间

在这篇文章中，我们将看到如何设置QCommandLinkButton的自动重复间隔时间。它定义了自动重复属性启用时自动重复间隔的长度，单位是毫秒。在自动重复属性中，当命令链接按钮下降时，按下、释放和点击的信号会以固定的时间间隔发出。自动重复属性默认是关闭的，尽管它可以在setAutoRepeat方法的帮助下被启用。

为了做到这一点，我们对命令链接按钮对象使用setAutoRepeatDelay方法。

语法： button.setAutoRepeatDelay(n)

参数： 它以整数为参数

返回： 它返回无

下面是实现方法
