Modernize your 4D interfaces with Fluent UI

Behind the scenes, a significant engineering effort has been carried out to bring native Fluent UI integration into 4D. This means that 4D forms can now be displayed using Microsoft’s Fluent UI design system, the same modern visual style that defines Windows, Office, and Teams. 4D is one of the first development environments to offer native WinUI integration, allowing developers to bring the authentic Fluent UI experience to their desktop applications. On the client side, the transition couldn’t be simpler. All it takes is enabling Fluent UI rendering in your project settings and making a few minor layout adjustments in your forms to enjoy the new, modern look.

This main window is technically called MDI (which stands for Multiple Document Interface) and now there’s a way to get rid of it and move to SDI (Single Document Interface) where application windows are all independent…

Interested? Just activate the SDI mode with a single checkbox and it’s done…without a line of code!
