What are "Screen Actions" used for in OutSystems?

Screen Actions in OutSystems are specifically designed to define the logic that occurs in response to user interactions on the screen. This functionality allows developers to create interactive and responsive applications by specifying what happens when users perform actions such as clicking a button, submitting a form, or navigating between screens.

When a user interacts with an interface element, like tapping a button, the corresponding Screen Action is triggered. This action can perform a variety of tasks, such as updating data, navigating to different screens, or triggering other logic within the application. By utilizing Screen Actions, developers can enhance user experience by ensuring the application reacts appropriately to user inputs.

In contrast, defining the layout of user interfaces pertains to the overall design and arrangement of elements on the screen, which is not the primary purpose of Screen Actions. While managing database connections and handling API requests are critical functions within application development, these processes are generally managed by different components in OutSystems, not directly by Screen Actions. Thus, the unique role of Screen Actions centers around the direct interaction between the user and the application logic.
