Changing Pages in Tkinter | Changing Frames in Tkinter | Shifting Between Multiple Pages in Tkinter

Switching pages or frames in Tkinter is a common requirement when building GUI applications. In this tutorial, we will cover how to switch pages and frames in Tkinter to develop multi-page applications.

Step 1: Setting up the Tkinter window

To start, we need to import the Tkinter library and create a root window for our application.

import tkinter as tk

root = tk.Tk()
root.title("Switch Pages in Tkinter")
root.geometry("800x600")

Step 2: Creating multiple frames

Next, we will create multiple frames to represent different pages of our application. Each frame will contain different widgets such as buttons, labels, or entry fields.

frame1 = tk.Frame(root, bg="red", width=800, height=600)
frame2 = tk.Frame(root, bg="blue", width=800, height=600)

frame1.pack(fill='both', expand=True)

Step 3: Defining functions to switch frames

Now, we need to create functions that will switch between the frames when called. We will use the pack_forget() method to hide the current frame and the pack() method to display the new frame.

def show_frame1():
    frame1.pack()
    frame2.pack_forget()

def show_frame2():
    frame2.pack()
    frame1.pack_forget()

Step 4: Adding buttons to switch frames

We will now create buttons that will call the functions defined above to switch between the frames.

button1 = tk.Button(frame1, text="Go to Page 2", command=show_frame2)
button1.pack()

button2 = tk.Button(frame2, text="Go to Page 1", command=show_frame1)
button2.pack()

Step 5: Running the application

Finally, we can run our application by starting the Tkinter main loop.

show_frame1()
root.mainloop()

Now, you should see a window with two frames and buttons to switch between them. This is a basic example of how to switch frames in Tkinter. You can extend this concept to create more complex multi-page applications by adding more frames and buttons and defining additional functions to switch between them.

In conclusion, switching pages or frames in Tkinter is a key aspect of building GUI applications. By following the steps outlined in this tutorial, you can create multi-page applications with ease. Experiment with different widgets, layouts, and functionalities to enhance your Tkinter applications.
