Question

我的问题是我不能在不使用grid（）的情况下将滚动条放在我的列表框中。除非我创建第二帧，否则我不能使用grid（）。我正在努力用一个类来创建第二个框架。下面是我使用该类的代码。我没有尝试将def标签（）添加到我的 init 中，因为它会抛出使用grid（）的语法。我想使用grid（）作为我的def列表框...所以如果我创建第二帧我应该能够使用grid（），如果他们在自己的框架内。我希望。

下面是另一批不使用类的代码，所有内容都是手动输入的，这样可以更好地显示应用程序。我宁愿使用我的顶级代码并学习如何正确地做事。

我不太清楚问题是什么。如果你想创建一个列表框和滚动条，并将它们放在一个框架中，那么你需要做的就是：创建一个框架并在其中放置一个列表框和滚动条。

def listbox(self):

    # create the frame
    lbframe = Frame(self)
    lbframe.pack(side="left", expand=True, fill=Y)

    # create a listbox and scrollbar as children of the frame
    lb = Listbox(lbframe, selectmode=SINGLE)
    scrollbar = Scrollbar(lbframe, orient="vertical")

    # pack the listbox and scrollbar in the frame
    lb.pack(side="left", expand=True, fill=BOTH)
    scrollbar.pack(side=RIGHT, fill=Y)

    for line in range(100):
        lb.insert(END, "This is line number " + str(line))

如果您只想将grid用于列表框和滚动条，那么您当然可以这样做。在这种特定情况下，我不确定它是否比使用pack提供任何好处。

使用带有tkinter的class（）创建第二帧
