如何在Tkinter中同时调用多个按钮

Question

我正在尝试创建一个有3个按钮的窗口。当用户单击其中一个按钮时，将调用分配的函数。这是我的代码，从我在文档中读到的内容，我尝试了一切，但我似乎无法克服它

我还添加了程序调用的函数，它们工作得很好，只是添加它们以供参考。此外，buttons（）函数只被调用一次，它是一个没有参数的简单调用

def buttons():
    root.geometry('1000x1000')

    btncreation = tkinter.Button(root, text='Order by Creation',
                                 command=creation)
    btncreation.pack()

    btnmodified = tkinter.Button(root, text='Order by Last Modified',
                                 command=lastmodified)
    btnmodified.pack()

    btnaccessed = tkinter.Button(root, text='Order by Last Accessed',
                                 command=lastaccessed)
    btnaccessed.pack()


def creation():
    lst.sort(key=os.path.getctime)
    num = 1
    for line in lst:
        dst = newpath + name + str(num) + suffix
        rename(line, dst)
        num += 1


def lastmodified():
    lst.sort(key=os.path.getmtime)
    num = 1
    for line in lst:
        dst = newpath + name + str(num) + suffix
        rename(line, dst)
        num += 1

按钮调用的函数：

def lastaccessed():
    lst.sort(key=os.path.getatime)
    num = 1
    for line in lst:
        dst = newpath + name + str(num) + suffix
        rename(line, dst)
        num += 1

另外，请，请不要对我的问题设置答案的格式。我只是想得到一些真诚的帮助，而不是关于如何“更好地安排我的问题”的5条评论。如果你需要更多的信息，我很乐意提供。但我不会回答关于格式的尖刻评论：）

buttons()

root.mainloop()

Answer 1

您可以从使用hide(root)开始，但在调用buttons()之前或之后，比如说，show(root)，因此：

# Rest of your code
hide(root)
# Rest of your code

show(root)
buttons()
