Question

我只想在窗口小于其内部框架时将滚动条添加到程序的每一页。

我的程序创建一个tkinter窗口，并将程序中某一部分的内容放入框架中。当用户转到程序的另一部分时，旧的框架获取器将被销毁，而新的框架将被放入。该想法来自另一个教程，该教程目前无法找到。它是这样的：

        self.switch_frame(StartPage)

    def switch_frame(self, frame_class):

        self.version.pack(anchor='se')

然后，我找到了有关如何添加滚动条的本教程Adding a scrollbar to a group of widgets in Tkinter。它说我需要把框架放在画布上。因此，尽管我可以将框架放置在画布中并向所有窗口添加滚动条，而不是将框架放置在窗口中。但是我不知道该怎么做以及在哪里做。我试图像这样在PTools类中进行更改：

class PTools(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)

        canvas = tk.Canvas(self, borderwidth=0, background="#ffffff")
        frame = tk.Frame(canvas, background="#ffffff")
        vsb = tk.Scrollbar(self, orient="vertical", command=canvas.yview)
        canvas.configure(yscrollcommand=vsb.set)
        vsb.pack(side="right", fill="y")
        canvas.pack(side="left", fill="both", expand=True)
        canvas.create_window((4,4), window=frame, anchor="nw")
        frame.bind("<Configure>", lambda event, canvas=canvas: onFrameConfigure(canvas))
        #self.geometry("%dx%d"%(self.winfo_screenwidth()+200,self.winfo_screenheight()+200))
        self._frame = None        
        self.title("Odatas Meister Tools")
        self.switch_frame(StartPage)

但这不起作用。我一开始会导入多个其他框架，这些框架对我认为的问题并不重要。我还将包括一个检查，以便仅在窗口小于我尝试添加的框架时才显示滚动条。每个框架的大小仅与几何图形管理器使之相同，才用小部件填充。我不手动设置大小。

将滚动条技术与tkinter方式相结合来更改框架
