由于您希望一次只显示一个窗口,您可以将各种“屏幕”定义为tk.Frame
s 并使用该lift
方法显示正确的框架:
import Tkinter as tk
class Page(tk.Frame):
def __init__(self, master, text, height, width, *args, **kwargs):
tk.Frame.__init__(self, *args, borderwidth=20, **kwargs)
self.height = height
self.width = width
button = tk.Button(self, text=text, font=('Comic Sans MS', 20),
command=lambda: self.callback())
button.pack(side="top", fill="both", expand=True)
def onlift(self):
root.geometry('{}x{}'.format(self.width, self.height))
self.lift()
class App(tk.Frame):
def __init__(self, *args, **kwargs):
tk.Frame.__init__(self, *args, **kwargs)
p1 = Page(self, 'This is page 1', height=200, width=300)
p2 = Page(self, 'Next page is 2', height=400, width=300)
p3 = Page(self, 'We love number 3', height=400, width=600)
p1.callback = p2.onlift
p2.callback = p3.onlift
p3.callback = p1.onlift
p1.place(x=0, y=0, relwidth=1, relheight=1)
p2.place(x=0, y=0, relwidth=1, relheight=1)
p3.place(x=0, y=0, relwidth=1, relheight=1)
p1.onlift()
root = tk.Tk()
app = App(root)
root.mainloop()
因此,在您的情况下,您可以定义 的其他子类tk.Frame
,并使用它们代替Page
.
