Energize your Web applications with the OutgoingMessage Class

In today’s digital world, a smooth and intuitive user experience is key to any web application’s success. A critical part of this experience is providing users with easy access to various resources—whether documents, images, or other data types. To make this possible, your server must manage and deliver different content formats efficiently.

With 4D’s new REST server feature, managing diverse content delivery is now easier than ever. Previously, the REST server could only return scalar, entity, or entity selection data. Now, it can deliver full web content directly—content ready for a browser to handle.

Downloading files or receiving binary data from the REST server is now straightforward, thanks to the new OutgoingMessage class. With it, you can easily customize responses to suit your needs.

Read on to explore how the OutgoingMessage class can enhance your application!

Qodly Studio for 4D: Dynamic User Interfaces with Page States

With 4D 20 R6, Qodly Studio for 4D introduced an exciting new feature: Page States. Perhaps you’ve already come across our previous post, but let’s explore what makes this feature so valuable for dynamic UIs.

Imagine UIs that adapt instantly to different user steps or contexts.

Here are some common use cases where Page States shine:

  • Enable or disable components based on user actions (e.g., activate the “Save” button only when all mandatory fields are filled).
  • Switch between light and dark modes with a simple toggle.
  • Restrict access to actions (read, update, etc.) based on user privileges.
