However, you may occasionally run into issues—in this case, a common one is the Combobox not getting a value when you try to retrieve it with the get() function. If you've encountered this frustrating issue, don't worry! This guide will walk you through the problem and provide a reliable solution. Understanding the Problem As you've experienced, when a Tkinter Combobox is employed in a new window, using the get() method on the associated variable may not return the expected output. Specifically, in the provided code, the intention was to retrieve and print the selected value from the Combobox, but it didn’t work as intended. The Scenario You have a Combobox created in a new window and a button to print the selected value. However, trying to get the selection using the StringVar associated variable leads to erroneous behavior. Let's take a look at the relevant snippet quickly: [[See Video to Reveal this Text or Code Snippet]] This code aims to print out what is stored in r_location_value, but it ends up not showing the correct selection of the Combobox. The Solution To effectively retrieve the value selected in the Combobox, we suggest modifying the retrieval method within your button's command function. Step-by-Step Guide to Fixing the Issue Define the Retrieval in the Button's Command The key adjustment you need to make is to retrieve the value directly from the Combobox itself rather than the StringVar. Implement the Change in Your Code Update the command function to use location.get() directly, which fetches the currently selected value. Here is the improved code segment: [[See Video to Reveal this Text or Code Snippet]] Final Code Example Here's how your full code could look after incorporating the above solution: [[See Video to Reveal this Text or Code Snippet]] Conclusion By changing the way you retrieve the value from the Combobox, you can seamlessly print the selected item without any hiccups. This solution not only resolves your issue but also enhances your understanding of working with the Tkinter library.
