How to Create a Responsive Bottom Frame in Tkinter GUI

Creating a user-friendly interface in your Tkinter applications is crucial, especially when it comes to providing an adaptable layout. One common requirement is to have a frame that stays fixed at the bottom of the window while the content above it changes size based on the window dimensions. In this post, we’ll explore how to achieve this in a simple and effective manner.

Understanding the Scenario

You may have faced a situation where you want your application window to consist of two frames: one at the top that expands and shrinks with the window size, and another fixed at the bottom for controls or information. The goal is to make sure that no matter how the user resizes the window, the top frame adjusts while the bottom frame remains locked in position.

The Problem

The original challenge is that your frames do not maintain their desired positions and sizes when the user changes the dimensions of the Tkinter window. Below is the previously used code that illustrates this issue:

In this setup, while you have fixed the size of the two frames, they are not adjustable to changes in the window size. Let's switch it up for a better solution!

The Solution

To make the top frame responsive and the bottom frame fixed, we will need to combine relheight and height for positioning the top frame, while using rely and y for the bottom frame. Here’s how you can do that:

Step-by-Step Implementation

Import Tkinter: Make sure you import the Tkinter library to use its functionalities.

Create the Main Window: Set up your root Tkinter window and define its size.

Configure Frames: Use the method place() effectively to define the layout of your frames.

Adjust Responsiveness: Ensure that the top frame occupies the remaining space as the window is resized.

Here's the updated code that accomplishes this:

Key Breakdown of the Code

relwidth=1: This makes the frame occupy the full width of the window.

relheight=1 with height=-80: This tells Tkinter to make the top frame take up all the available height except for the bottom frame’s height (which is 80 pixels).

rely=1 and y=-80: These options position the bottom frame exactly at the bottom of the window, with respect to the height of the window.

Conclusion

With this approach, you have now seamlessly integrated a responsive top frame that adjusts its size with the window while keeping the bottom frame fixed at all times. This not only enhances the aesthetics of your application but also improves the usability, providing a better experience for your users.
