What are the basic building blocks or visual elements of screens in OutSystems?

In OutSystems, widgets serve as the fundamental visual elements or building blocks used to create screens. They are versatile components that can be combined and configured to form the user interface of applications. Widgets include elements such as buttons, text inputs, images, and other interactive components that users interact with during their experience in the application.

By utilizing these widgets, developers can design user-friendly and visually appealing screens that facilitate user interaction with the application's functionalities. Containers, templates, and forms are also important in screen design, as they help in organizing and structuring the layout or group similar widgets together, but the term 'widgets' specifically refers to the individual interactive elements that make up the user interface. Therefore, understanding the role of widgets is essential for effectively building and managing screens in OutSystems applications.
