Question

此代码由带有滚动条的输入框组成，滚动条应显示在最右侧。但是，框不可见，滚动条也不在正确的位置。我想这是在画布中传递/创建帧的问题，但似乎没有任何效果。我将不胜感激任何帮助。

    from Tkinter import *
    from random import randint

    root = Tk()
    root.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(),root.winfo_screenheight()))

    global label2

    def onFrameConfigure(canvas):
        canvas.configure(scrollregion=canvas.bbox("all"))

    def populate(label2):
        Label(label2, bg='Light Blue',font = ("Verdana 10 bold"),text="NUMBER OF COMPONENTS REQUIRED").grid(row = 1, column = 1, sticky = W, padx = 10)
        Label(label2, bg='Light Blue',text="COMPONENT 1").grid(row = 4, column = 1, padx = 10,sticky=W)
        Label(label2, bg='Light Blue',text="COMPONENT 2").grid(row = 5, column = 1, padx = 10, sticky=W)

   canvas.pack(side = "right", fill = "both", expand = True)
   canvas.grid(sticky = NE+SE)
   canvas.create_window((4,4), window = label2, anchor = "ne")

   frame.bind("<Configure>", lambda event, canvas = canvas: onFrameConfigure(canvas))

   populate(frame)

   root.mainloop( )

Answer 1

您已将label2作为root的孩子，但随后您在画布中嵌入了label2。但是，您的populate方法会将小部件放入frame。

Tkinter内容和滚动条未正确显示
