[Tkinter-discuss] 回复： why tkinter do not quit?

[守株待兔]

it's so strage for me to understand
code1
import Tkinter 
top=Tkinter.Tk()
button=Tkinter.Button(top,text = 'Hello Button',command = top.quit)
button.pack()
top.mainloop()

code1 can run ,when you click button ,it will quit

code2
import Tkinter 
top=Tkinter.Tk()
button=Tkinter.Button(top,text = 'Hello Button',command = top.quit())
button.pack()
top.mainloop()


code2 can run too ,but when you click button,it will  not  quit.

what is the difference  between  quit and quit() ??

 Hi,

root.quit is a reference to object field but not a quit() method.
Try using root.quit() This should resolve an issue.

 here is my program:
from Tkinter import *
def helloButton():
    print 'hello button'
    root.quit
root = Tk()
Button(root,text = 'Hello Button',command = helloButton).pack()
root.mainloop()
 
when i click on my  button,print is ok,why  root.quit have no effect?
