我正在尝试制作基于菜单的应用程序。它需要在一个帧中显示多个屏幕，即当用户按下“下一个”按钮时，它将清除输出并显示他们选择的选项。我尝试过Toplevel方法，但我认为不是答案。
非常感谢任何帮助。

基本思想是从包含框架开始，然后＆＃34;堆叠＆＃34;所有屏幕都在彼此之上。然后，要显示特定屏幕，只需将其提升到堆叠顺序的顶部即可。
以下是一个例子：
import Tkinter as tk
class Screen(tk.Frame):
'''This defines one "screen"'''
def __init__(self, parent, label):
tk.Frame.__init__(self, parent)
l = tk.Label(self, text=label)
self.entry = tk.Entry(self)
l.pack(side="top", fill="x")
self.entry.pack(side="top", fill="x", padx=20)
self.entry.insert(0, "this is the entry for " + label)
class Example(tk.Frame):
'''This is the main application'''
def __init__(self, *args, **kwargs):
tk.Frame.__init__(self, *args, **kwargs)
# an array of screens, and a pointer to the current screen
self.current = None
self.screens = []
# the basic layout is a toolbar on top and
# a container on the bottom which will hold all
# of the "screens"
container = tk.Frame(self)
toolbar = tk.Frame(self)
toolbar.pack(side="top", fill="x")
container.pack(side="bottom", fill="both", expand=True)
# create 10 "screens" that we can cycle through
for i in range(10):
screen = Screen(container, "screen %s" % i)
screen.place(x=0, y=0, anchor="nw", relwidth=1.0, relheight=1.0)
self.screens.append(screen)
# create a "next" button to cycle through the screens
next = tk.Button(toolbar, text="next", command=self.next)
next.pack(side="right")
# start by showing screen zero
self.show(0)
def show(self, index):
self.current = index
self.screens[self.current].lift()
def next(self):
'''Show the next screen, or screen zero if at the end'''
if self.current == len(self.screens)-1:
self.show(0)
else:
self.show(self.current+1)
if __name__ == "__main__":
root = tk.Tk()
root.geometry("600x400")
Example(root).pack(side="top", fill="both", expand=True)
root.mainloop()
