Question

我有一个标签设置为一定的大小但是当我运行我的程序时，主窗口不够大，无法看到整个标签。如何增加主窗口的大小？我尝试了不同的选择，但我没有运气。

import win32com.client
import os
# import threading # use the Timer
import tkinter

from tkinter import Tk, Label, Button

class myGUI:

    def timer(self):

        import pythoncom       
        pythoncom.CoInitialize()  

        outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")

        inbox = outlook.GetDefaultFolder(6) 



        messages = inbox.Items
        message = messages.GetLast()
        body_content = message.Subject # can be Body, To, REcipients, Sender, etc


        self.answer_label['text'] = (body_content) # orginally used body_content.encode("utf-8") to fixed character encoding issue


        self.master.after(20, self.timer) # after needs to be called from an existing widget such as master
                                         # In this case, the after method is used to refresh the e-mails instead of threading

    def __init__(self, master):
        self.master = master
        master.title("CheckStat")


        self.answer_label = Label(master, text='', fg="light green", bg="dark green", font="Helvetica 16 bold italic")
        self.answer_label.place(height=100, width=600)

        self.timer()


root = Tk()
my_gui = myGUI(root)
root.mainloop()

如果您使用pack或grid代替place，则窗口会自动增大或缩小以适合标签的内容。如果有的话，place最好用得非常谨慎。

如果您想使用place，可以使用根窗口的geometry方法为窗口指定显式大小。

例如，要使根窗口为600x100，您应该添加以下行：

root.geometry("600x100")

如何在Python中更改主Tkinter窗口的大小？
