Using buttons in Tkinter to navigate to different pages of the application?

by

Make each page a frame. Then, all your buttons need to do is hide whatever is visible, then make the desired frame visible.

A simple method to do this is to stack the frames on top of each other (this is one time when place makes sense) and then ,lift() the frame you want to be visible. This technique works best when all pages are the same size; in fact, it requires that you explicitly set the size of containing frame.

The following is a contrived example. This isn’t the only way to solve the problem, just proof that it’s not a particularly hard problem to solve:

import Tkinter as tk

class Page(tk.Frame):
    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self, *args, **kwargs)
    def show(self):
        self.lift()

class Page1(Page):
   def __init__(self, *args, **kwargs):
       Page.__init__(self, *args, **kwargs)
       label = tk.Label(self, text="This is page 1")
       label.pack(side="top", fill="both", expand=True)

class Page2(Page):
   def __init__(self, *args, **kwargs):
       Page.__init__(self, *args, **kwargs)
       label = tk.Label(self, text="This is page 2")
       label.pack(side="top", fill="both", expand=True)

class Page3(Page):
   def __init__(self, *args, **kwargs):
       Page.__init__(self, *args, **kwargs)
       label = tk.Label(self, text="This is page 3")
       label.pack(side="top", fill="both", expand=True)

class MainView(tk.Frame):
    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self, *args, **kwargs)
        p1 = Page1(self)
        p2 = Page2(self)
        p3 = Page3(self)

        buttonframe = tk.Frame(self)
        container = tk.Frame(self)
        buttonframe.pack(side="top", fill="x", expand=False)
        container.pack(side="top", fill="both", expand=True)

        p1.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
        p2.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
        p3.place(in_=container, x=0, y=0, relwidth=1, relheight=1)

        b1 = tk.Button(buttonframe, text="Page 1", command=p1.show)
        b2 = tk.Button(buttonframe, text="Page 2", command=p2.show)
        b3 = tk.Button(buttonframe, text="Page 3", command=p3.show)

        b1.pack(side="left")
        b2.pack(side="left")
        b3.pack(side="left")

        p1.show()

if __name__ == "__main__":
    root = tk.Tk()
    main = MainView(root)
    main.pack(side="top", fill="both", expand=True)
    root.wm_geometry("400x400")
    root.mainloop()
