当使用tk.Tk定义多个时，将类定义的tkinter对象放在单个帧上

根据我从Sentdex获得的建议，我编写了一个多页Python / Tkinter应用程序，其中包括在tk.Tk下生活的许多帧的单个帧的单帧上提供时间移动图 . 移动图的编码稍微复杂，所以我选择在类中定义画布：GrpCanvas（tk.Canvas） .

我的问题是这个程序结构似乎导致画布对象出现在我的所有21个页面框架上！如何管理代码以便 graphcanvas=GrpCanvas(HomePage) 仅显示在该页面上？我已经注释掉了一些父定义，以显示我试图做的事情（并且失败了） . 我使用的是Python 3.4.4 .

我在下面显示了代码（尽可能减少以显示问题）：

#Avoiding canvas on all pages when pages are managed using tk.Tk
