Tkinter 显示按钮而不是标签

Question

我正在创建一个小应用程序，它将从用户那里获取有关银行交易的详细信息，然后将其显示在表格中。 我目前正在使用 CSV 文件来存储数据，然后当输入一条新数据时，它也会显示出来。

我有一个标签列表，然后在它们底部有一个按钮来提交新条目。我遇到的问题是当表格的长度超过它开始时的长度时会出现显示错误。

class accountant(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        master.title("Accountant")
        self.pack()
        self.numIncoming = 0
        self.numOutgoing = 0
        self.incoming = fs.fileStore("incoming", "csv")
        print("log: incoming.csv opened sucessfully")
        self.outgoing = fs.fileStore("outgoing", "csv")
        print("log: outgoing.csv opened sucessfully")
        self.setup()

    def setup(self):

filestore 只是一个基本上使用打开 csv 的类 reader = csv.reader(open(file+'.'fileExt)) 其中file和fileExt是传入的参数。

这是新条目后的图像。底部的两个按钮应保持原样，顶部的两个按钮应为左列中的 d e f ，右列中应为空格

将 self.pack() 替换为 self.grid()。此外，要将 Label 更改为 Button，您还必须定义一个在按下 Button 时执行的命令函数，请参见下面的代码

bttn = tk.Button(self, text = "buttontitle",  command = self.do_function )
bttn.grid(row = 14, column = 4, sticky = W)


def do_function():
    print "HI"
