我正在构建一个日历，允许用户按下上个月和下个月创建的按钮来循环显示月份和年份。基本上我想要主窗口做的是在点击PREV或NEXT月份时使用正确的日期更新新月，它只会发出日期按钮，显示月份的特定日期重叠。 以下是我遇到问题的部分：
def prevMonth(self):
try:
self.grid_forget()
#SHOULD REFRESH THE WINDOW SO BUTTONS DONT OVERLAP
print "forgeting"
except:
print "passed the forgetting"
pass
lastMonth = self.month - 1
self.month = lastMonth
self.curr_month()
def nextMonth(self):
try:
self.grid_forget()
#SHOULD REFRESH THE WINDOW SO BUTTONS DONT OVERLAP
print "forgeting"
except:
print "passed the forgetting"
pass
nextMonth = self.month + 1
self.month = nextMonth
self.curr_month()
当程序在网格不刷新的月份之间迭代时，它只会重叠日期和月份。我已经尝试过在研究时间里找到的一切。 “self.destroy（）”只是创建一个空白窗口。 “self.grid.destroy（）”返回错误，该函数没有属性破坏。我已经尝试让网格的孩子在自己内部的所有全局变量，我不能正确地遍历几个月，所以设置是永久性的，但我觉得我错过了一些简单的工作，刷新网格并重新打印基于更新月份。
您能否指出我正确的方向或纠正我错过的错误？
以下是整个计划

这是建议答案的修改版本，其中还包括允许用户在月份中循环并且还将增加年份的原始期望意图。

Tkinter效率很高。对于您拥有的小部件数量，最初创建它们不会对性能产生太大影响。这是一个与你试图做的一样的样本。
