Displaying a Popup Window on Click in PySimpleGUI

When developing applications with PySimpleGUI, a common requirement is to display additional information or results in a popup window. For instance, if you want to show results from an API after a user selects an item, it can be frustrating when nothing appears upon clicking a button. Don't worry! In this guide, we'll walk you through the steps to create a popup window efficiently using PySimpleGUI.

Identifying the Problem

In this scenario, we are trying to create a simple interface where users can select images from a directory, and upon selecting an image, we want to display certain results retrieved from an API in a popup window. However, without the correct implementation, nothing shows when the button is clicked.

Solution Breakdown

Step 1: Set Up the PySimpleGUI Environment

Before we dive into the popup functionality, make sure you have PySimpleGUI installed. You can do this via pip with the following command:

Step 2: Implementing the Popup Functionality

To ensure the popup window displays correctly, you need to modify the respective part of your code where you handle the API results. The key here is to use the sg.Popup() function. Here’s how you can do it:

After retrieving the license plate information, incorporate the following line into your code to create a popup:

Step 3: Understanding the Popup Behavior

Popup Features: By adding keep_on_top=True to your sg.Popup(), you ensure that the popup remains on top of other windows. This way, users can see the message immediately.

Potential Overlap: It’s important to note, however, that if another window also has a "keep on top" setting enabled, it could potentially cover your popup. Be mindful of the window management in your app to avoid this issue.

Step 4: Complete Example

Here’s an example snippet where we incorporate the sg.Popup() within your existing code structure:

Final Note on User Experience

Popup windows are a great way to enhance user interaction by providing immediate feedback or additional information without cluttering the main interface. Just remember to implement them thoughtfully to ensure a seamless experience for your users.

Conclusion

Incorporating a popup window in your PySimpleGUI application is relatively simple and can greatly enhance interactivity. With just a few lines of code, you can present essential information in a way that grabs your user's attention. Try implementing the code above in your project, and you’ll be able to display results like a pro.

Feel free to experiment with additional customization in the popup function to suit your application's style and usability needs. Happy coding!
