When using PyQt5, you may encounter a common error: AttributeError: ‘NoneType’ object has no attribute ‘clicked’when using the connect() function. Fortunately, with the use of some quick expert tips and tricks, you can solve this error quickly.

The Problem

The error can be quite frustrating as it prevents your code from executing properly. To understand the error, it’s important to know that the connect() function is used to link signals and slots in PyQt5. It allows you to connect a widget to a slot that handles events triggered by that widget.

The error message

The AttributeError: ‘NoneType’ object has no attribute ‘clicked’ error message occurs when the programmer tries to connect a signal to a slot that doesn’t exist. Basically, the function is looking for a slot to connect to but can’t find it, so it throws an error.

Causes of the Error

There are several causes why the connect() function couldn’t find a slot to connect to:

Typo in Slot Name

One of the most common reasons for the error is a typo in the slot name. This happens when the programmer misspells the name of the slot function or forgets to define it.

Wrong Widget Object Type

Another reason could be the wrong widget object being passed as an argument for the connect() function. The widget object must be the one that emits the signal you want to connect to the slot function.

Incorrect Signal Syntax

Another cause of the error could be that the signal syntax is incorrect. The signal’s name needs to be followed by an argument list that matches the data the signal sends.

Tips to Solve the Error

To solve the AttributeError: ‘NoneType’ object has no attribute ‘clicked’ error, you can follow these expert tips and tricks:

Use PyQt5 Signals and Slots Documentation

One way to avoid the error is to refer to the official PyQt5 Signals and Slots Documentation. Here, you can find a list of signals and their associated arguments. This documentation can help you determine the correct syntax for your signal and slot.

Check for Typing Errors

You can also double-check your code for any spelling or typing errors. Make sure that the names of the signals and slots are spelled correctly and match in all instances.

Check for Correct Widget Type

You must ensure that the widget object you’re connecting with connect() function is the one where the signal originates. If it isn’t, then you will get the error message.

Double Check Signal Syntax

If you’ve verified that the widget is correct, the next step is to check the syntax of the signal. Take heed of what types of arguments the signal sends and ensure that they match your code’s slot arguments.

Use Debugging Techniques

One of the best ways to troubleshoot the error is to use debugging techniques such as inserting print statements in your code. Use this to track the flow of execution and identify where the problem lies.

Table Comparison

Here is a table comparing the possible causes and solutions of the AttributeError: ‘NoneType’ object has no attribute ‘clicked’ error:

Cause Solution
Typo in Slot Name Double-check spelling and syntax of the slot name.
Wrong Widget Type Ensure the widget object being passed to connect() is the correct one.
Incorrect Signal Syntax Verify the signal syntax and the signal arguments match with the slot arguments.


The AttributeError: ‘NoneType’ object has no attribute ‘clicked’ error can be fixed by using the right tips and tricks. The possible causes of the error are typos in the slot name, incorrect widget type, and faulty signal syntax. Always debug your code and use the official PyQt5 documentation to avoid this error altogether. By following these expert tips and tricks, you should be able to solve the error quickly and continue working on your PyQt5 program with ease.
