问题描述
我现在遇到了死胡同 - 首先，当您单击一个动态按钮时，会进行函数调用，并且它确实返回所单击按钮的名称。
然而，它应该调用的fEndDay函数似乎没有运行。
编辑：这一天正在运行。 刚刚重新启动了 Liclipse，它开始工作了。 没有解释。 但是，按钮等待问题仍然存在。
我现在也有点卡住了。 本质上我想要：
-
而当日 < 总天数....
- 运行每日事件，更新屏幕对象。
- 通过单击按钮进行选择。
- 增加当前日期。
但是，日循环会停止显示屏幕（即处理循环）。 我想如果有代码将对象显示向上推并处于无限循环中，该循环被按钮单击破坏，那就可以了。 其他想法？ 下面的当前代码。

# add to it.

您希望每天运行一次函数这一事实与希望动画每秒运行 30 帧没有什么不同。 您实际上想要一个运行 1 fpd（每天一帧）的“动画”。
实现这一点的方法是创建一个每天运行一次的函数。
def do_once_a_day():
...
接下来，创建一个每天调用一次该函数的函数：
def call_daily(self):
self.do_once_a_day()
if self.vDayNumber <= self.vFinalDay:
root.after(1000*60*60*24, self.call_daily)
这将导致每 24 小时调用一次do_once_a_day 。
然后，您可以在该函数中做任何您想做的事情。
