How does the expression widget function in the context of displaying data?

The expression widget plays a crucial role in displaying data within OutSystems applications by calculating and presenting dynamic values. This widget is designed to process and render information that can change based on user interactions, database queries, or other runtime events. This ability to display values that are not just static enhances the interactivity and responsiveness of the application.

When using the expression widget, developers can insert formulas or reference variables that hold dynamic data, allowing the content to update in real-time as the application state changes. For example, if a user makes a selection that updates a value or if data retrieved from a database changes, the expression widget can reflect those changes immediately on the user interface.

In contrast, the other options either describe more limited functionalities or misrepresent the capabilities of the expression widget. It is not limited to displaying static images, nor does it only handle text. While it can display text, this is just one aspect of its functionality; the strength of the expression widget lies in its ability to calculate and showcase data dynamically, which is essential for developing modern web applications. Additionally, the expression widget does not generate records in a list format; that is a different functionality typically managed by list widgets or tables designed for displaying collections of data.
