tkinter 网格重叠 [英] tkinter grid overlapping
问题描述
我正在构建一个日历，允许用户通过按下上个月和下个月创建的按钮来循环浏览月份和年份.本质上，我希望主窗口做的是在单击 PREV 或 NEXT 月份时使用正确的日期更新新的月份，它确实如此，唯一的问题是在循环时显示该月特定日期的日期按钮重叠.以下是我遇到问题的部分:
I am building a calendar that allows the user to cycle through the months and years by pressing the buttons created of the previous month and next month. Essentially what I want the main window to do is update with the new month upon clicking PREV or NEXT month with the correct days, which it does, only issue is the day buttons that display the specific days of the month overlap when cycling through. Below is the part where I am having issues:
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()
当程序在月份之间迭代时，网格不会刷新，它只会与日期和月份重叠.我已经尝试了我在研究时间里发现的一切.self.destroy()"只是创建一个空白窗口.self.grid.destroy()"返回错误，函数没有属性destroy.我已经尝试使网格的子项成为 self 中的所有全局变量，但我无法正确地遍历几个月，因此设置是永久性的，但我觉得就刷新网格和重新打印基于更新的月份.
When the program iterates between the months the grid does not refresh it just overlaps the days and months. I have tried EVERYTHING I found in my hours of research. "self.destroy()" merely creates a blank window. "self.grid.destroy()" returns and error that function has no attribute destroy. I have tried making the children of grid all global variables within self and I cant iterate through the months correctly so the set up is permanent but I feel like I am missing something simple as far as working with refreshing the grid and reprinting the based upon the updated month.
能否请您指出正确的方向或纠正我遗漏的错误?
Can you please point me in the right direction or correct the error I am missing?
以下是整个程序

推荐答案
这是建议答案的修改版本，其中还包括允许用户循环使用月份的原始预期意图，并且还将增加年份.
This is a modified version of the proposed answer that also includes the original desired intent of allowing the user to cycle through the months and will also increment the year.
