Here is a minimal example of one method I used recently; the key is in PythonGUI.show_frame, which moves the appropriate frame to the front for display.
import Tkinter as tk
class BaseFrame(tk.Frame):
"""An abstract base class for the frames that sit inside PythonGUI.
Args:
master (tk.Frame): The parent widget.
controller (PythonGUI): The controlling Tk object.
Attributes:
controller (PythonGUI): The controlling Tk object.
"""
def __init__(self, master, controller):
tk.Frame.__init__(self, master)
self.controller = controller
self.grid()
self.create_widgets()
def create_widgets(self):
"""Create the widgets for the frame."""
raise NotImplementedError
class ExecuteFrame(BaseFrame):
"""The application home page.
Attributes:
new_button (tk.Button): The button to switch to HomeFrame.
"""
def create_widgets(self):
"""Create the base widgets for the frame."""
self.new_button = tk.Button(self,
anchor=tk.W,
command=lambda: self.controller.show_frame(HomeFrame),
padx=5,
pady=5,
text="Home")
self.new_button.grid(padx=5, pady=5, sticky=tk.W+tk.E)
class HomeFrame(BaseFrame):
"""The application home page.
Attributes:
new_button (tk.Button): The button to switch to ExecuteFrame.
"""
def create_widgets(self):
"""Create the base widgets for the frame."""
self.new_button = tk.Button(self,
anchor=tk.W,
command=lambda: self.controller.show_frame(ExecuteFrame),
padx=5,
pady=5,
text="Execute")
self.new_button.grid(padx=5, pady=5, sticky=tk.W+tk.E)
class PythonGUI(tk.Tk):
"""The main window of the GUI.
Attributes:
container (tk.Frame): The frame container for the sub-frames.
frames (dict of tk.Frame): The available sub-frames.
"""
def __init__(self):
tk.Tk.__init__(self)
self.title("Python GUI")
self.create_widgets()
self.resizable(0, 0)
def create_widgets(self):
"""Create the widgets for the frame."""
# Frame Container
self.container = tk.Frame(self)
self.container.grid(row=0, column=0, sticky=tk.W+tk.E)
# Frames
self.frames = {}
for f in (HomeFrame, ExecuteFrame): # defined subclasses of BaseFrame
frame = f(self.container, self)
frame.grid(row=2, column=2, sticky=tk.NW+tk.SE)
self.frames[f] = frame
self.show_frame(HomeFrame)
def show_frame(self, cls):
"""Show the specified frame.
Args:
cls (tk.Frame): The class of the frame to show.
"""
self.frames[cls].tkraise()
if __name__ == "__main__":
app = PythonGUI()
app.mainloop()
exit()
