-
root.destroy()
類方法關閉 Tkinter 視窗 -
destroy()
非類方法關閉 Tkinter 視窗 -
直接將
root.destroy
函式與按鈕的command
屬性關聯 -
root.quit
關閉 Tkinter 視窗
當使用者單擊 Tkinter 按鈕時,我們可以使用附加在按鈕上的函式或命令來關閉 Tkinter GUI。
root.destroy()
類方法關閉 Tkinter 視窗
try:
import Tkinter as tk
except:
import tkinter as tk
class Test():
def __init__(self):
self.root = tk.Tk()
self.root.geometry('100x50')
button = tk.Button(self.root,
text = 'Click and Quit',
command=self.quit)
button.pack()
self.root.mainloop()
def quit(self):
self.root.destroy()
app = Test()
destroy()
用來關閉視窗。
destroy()
非類方法關閉 Tkinter 視窗
try:
import Tkinter as tk
except:
import tkinter as tk
root = tk.Tk()
root.geometry("100x50")
def close_window():
root.destroy()
button = tk.Button(text = "Click and Quit",
command = close_window)
button.pack()
root.mainloop()
直接將 root.destroy
函式與按鈕的 command
屬性關聯
我們可以直接將 root.destroy
函式繫結到按鈕 command
屬性,而無需定義額外的 close_window
函式。
try:
import Tkinter as tk
except:
import tkinter as tk
root = tk.Tk()
root.geometry("100x50")
button = tk.Button(text = "Click and Quit", command = root.destroy)
button.pack()
root.mainloop()
root.quit
關閉 Tkinter 視窗
root.quit
不僅退出 Tkinter 視窗,而且退出整個 Tcl 直譯器。
如果你的 Tkinter 應用不是從 Python Idle 啟動的,可以使用這種方法。如果從 Idle
呼叫你的 Tkinter 應用程式,則不建議使用 root.quit
,因為 quit
不僅會殺死你的 Tkinter 應用程式,還會殺死 Idle
本身,因為 Idle
也是 Tkinter 應用程式。
try:
import Tkinter as tk
except:
import tkinter as tk
root = tk.Tk()
root.geometry("100x50")
button = tk.Button(text = "Click and Quit", command = root.quit)
button.pack()
root.mainloop()
