Creating Multiple Labels in Tkinter: A Simple Guide to Displaying a Timer

Are you looking to implement a timer display using Tkinter in your Python application? If you're playing a game and want to keep track of time via a simple overlay, this article will guide you through the process of creating multiple labels each time a key is pressed.

The Problem

In the scenario originally posed, the user wanted to create a timer that triggers when the "p" key is pressed. The challenge was to showcase this timer using a Label widget in the overlay. However, the user's initial code did not successfully create multiple labels, which was needed for displaying the updated timer continuously.

Solution: Using Threads to Create Dynamic Labels

To solve this, we will utilize the keyboard module to detect key presses and threading to manage the timer functionality efficiently without freezing the GUI. Here's how you can implement this solution step-by-step:

Step 1: Set Up Your Environment

First, ensure you have the required libraries installed:

Step 3: Create the Timer Functionality

Now, let's define a thread function that monitors for the key press:

Step 4: Update the Label When Key is Pressed

Next, define the function that creates and updates the label:

This function will create a new label each time the "p" key is pressed, displaying the current time.

Step 5: Set Up the Main GUI

Now, set up the main Tkinter window:

Step 6: Start the Thread Listener

Finally, we need to create a thread that runs the keyboard listener:

Final Thoughts

With this setup, you successfully create an overlay that generates multiple labels, each showing the time when "p" is pressed. This method is efficient and keeps the graphical user interface responsive, thanks to threading.

Feel free to customize the label text or design further according to your game requirements. Happy coding, and enjoy your game!
