我在Python上创建了两个函数:
当我启动它们时,新的窗口运行得很好,但是create_button会显示[无法调用“button”命令:应用程序已被销毁]就好像我的主窗口被破坏了一样。。。但我的窗户还开着!在
。。。你知道吗??在
import Tkinter
from Tkinter import *
def new_window():
master = Tk()
def create_buttons(display):
new_button= Button(master, text=display)
new_button.pack()
new_window() ### OK, CREATES A WINDOW
create_buttons('text') ### DISPLAYS FOLLOWING BUG :

正如J.F.Sebastian所说,您需要使
master
变量可用于创建按钮的位置。执行此操作的某些代码可能如下所示:这不漂亮,但应该足够好,可以随意摆弄一下。如果代码变得严肃起来,最好将新窗口及其按钮打包到自己的类中。在
