在 Tkinter 中刷新窗口 [英] Refreshing a window in Tkinter

问题描述

我正在尝试在 Tkinter 中创建一个 GUI 并且想知道如何刷新窗口，即如果我填充一个矩形，我希望 GUI 在指定时间后将其删除.我该怎么做呢?Tkinter 上的文档似乎很薄...

I am trying to make a GUI in Tkinter and am wondering how to refresh a window, namely if I fill in a rectangle, I want the GUI to delete it a specified time later. How would I go about doing this? Documentation on Tkinter seems to be thin...

推荐答案

每个 Tkinter 小部件都有一个 after 方法，您可以使用它来调用矩形删除函数，例如在下面的示例中，我首先使用 after 更改 msg，然后使用 after

Each Tkinter widget has a after method, which you can use to call your rectangle delete function e.g. in the example below first I change a msg using after, and then destruct the window using after

from Tkinter import *

def changeMsg():
    label.configure(text="I will self destruct in 2 secs")
    label.after(2000, root.destroy)

root = Tk()
mainContainer = Frame(root)
label = Label(mainContainer, text="")
label.configure(text="msg will change in 3 secs")
label.pack(side=LEFT, ipadx=5, ipady=5)
mainContainer.pack()
label.after(3000, changeMsg)
root.title("Timed event")
root.mainloop()
