How to Position a Resized Window in Tkinter

Creating applications with graphical interfaces can be frustrating, especially when trying to manage the position and size of your windows. In Python's Tkinter library, you may encounter challenges when resizing windows and placing them correctly on the screen. This guide will walk you through solving the specific problem of positioning resized Tkinter windows accurately.

Understanding the Problem

You want to resize your Tkinter windows to fit a device but also place them in specific spots on the screen. The code provided below attempts to set up two windows, one taking up two-thirds of the screen width and the second taking up one-third. However, you encounter a TypeError stating that you cannot concatenate a string with an integer.

Example Code That Causes an Error

[[See Video to Reveal this Text or Code Snippet]]

The error arises because of the way you are concatenating the geometry parameters: + 0 + 0 is incorrect as it tries to concatenate integers (0) with a string.

Solution Overview

The geometry method in Tkinter uses the format widthxheight±x±y, where width and height specify the dimensions of the window, and x and y specify the position of the window on the screen. To correctly position your windows without causing errors, the following adjustments can be made.

Step-by-Step Solution

Adjust Geometry String Format: Ensure that the geometry string correctly includes both size and position parameters in the right format.

Example Code Fix: Here’s how you should modify your original code:

Key Points

The geometry method format you should use is "%dx%d+ %d+ %d", which allows you to specify both size and position.

Ensure that both the dimensions and the position (x and y coordinates) are all included and properly formatted as integers where necessary.

Conclusion

By following the corrected code structure provided above, you can successfully resize your Tkinter windows to fit your device's screen and place them in specific spots without encountering the TypeError. Tkinter can be quite powerful for GUI development, and with a little understanding of its geometry management, you can create visually appealing interfaces with ease. Happy coding!
