How to Disable Editing and Resizing of QTableWidget in PyQt5 While Keeping Scrolling Enabled

In the world of graphical user interfaces (GUIs), user experience plays a crucial role in the design and functionality of applications. When using QTableWidget in PyQt5, you may encounter situations where you want to restrict users from editing or resizing the table but still want to enable basic actions like scrolling and selecting data. In this post, we'll address this specific requirement and provide a solution that allows you to achieve these functionalities seamlessly.

The Problem

Imagine you have a QTableWidget in your PyQt5 application. You want to ensure that:

Users cannot edit the table cells.

Users cannot resize the width of the columns.

Users can still scroll through the table and select the data.

You might start with the right idea of using setEditTriggers to disable editing. However, you might still encounter issues with users being able to resize the columns, which can disrupt the layout you intended. Alternatively, disabling the table completely would prevent scrolling and selection, which is not ideal for user interaction.

The Solution

To solve this problem, we need to break down the required steps into clear actions. Let’s go through each of them:

Step 1: Disable Editing

To disable editing of the QTableWidget, you can use the following method as your starting point:

This line effectively prevents users from making changes to the cells, which is the first step towards achieving your goal.

Step 2: Prevent Resizing of Columns

Even after disabling editing, you may still face issues with users dragging column headers to resize the columns. To prevent this, you need to set the resizing policy for the column headers specifically:

This command sets the resize mode for the horizontal header, ensuring that the widths of the columns cannot be altered. This means that the columns will maintain their set width, and users will not be able to adjust them.

Step 3: Retain Scrolling and Selection Features

With the above steps implemented, you’ve already ensured that editing and resizing are disabled. The good news is that by simply not disabling the table widget itself, scrolling and selection features remain fully functional! Users will still be able to scroll through the data and select it for copying without any issues.

Summary

By following these steps, you can easily configure your QTableWidget in PyQt5 to achieve the desired behavior:

Disable cell editing using setEditTriggers.

Prevent column resizing by setting the header's resize mode to Fixed.

Allow scrolling and selection by ensuring not to disable the table widget itself.

This approach strikes a balance between restricting modifications and preserving essential interaction functionality, providing a smoother user experience in your PyQt5 application.

Following these simple steps will help you maintain a clean, user-friendly interface in your applications while ensuring your data remains unaltered. Now you're ready to implement these practices in your own projects!
