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.
Track, Audit, Optimize: Take Control of Your 4D Web Sessions
Since the introduction of scalable sessions, server-side session management has become an important component of modern 4D architectures. These sessions enable fine-tuned scalability for web applications, but also require stricter supervision to guarantee performance, stability, and license control. With 4D 21, you now have a comprehensive means of inspecting all open web sessions, whether they originate from REST connections, SOAP calls, or 4DACTION requests.
Find the right spot in your 4D Write Pro document with AI
In 4D applications, large documents are commonplace: financial reports, internal guidelines, technical manuals… Searching for an exact keyword often isn’t enough. Scrolling through 30-page reports to find one paragraph is not only time-consuming but also error-prone. This is where AI can help.
The semantic approach based on vectors, introduced in 4D 20 R10, already makes it possible to find a relevant 4D Write Pro document even when different wordings are used (for example, “insert image” vs. “add picture”).
But what happens when a document spans multiple pages and covers various subtopics? Even if the entire text can be converted into a single vector, results are often better when we work at a finer scale. This is the idea behind chunking: splitting a document into coherent segments, each represented by its own vector.
This is precisely what allows us to go further: retrieving not only the right document, but also the exact passage that matches the search.
Intelligent 4D Write Pro document analysis with AI
In many business applications, users enter or receive unstructured text: customer feedback, internal notes, support tickets, reports, and more. This content represents valuable information, but it’s difficult to leverage without specific processing.
This is where artificial intelligence becomes a powerful tool: by automatically analyzing the written content of a 4D Write Pro document, it can extract useful metadata for understanding, sorting, or prioritizing.
In this demonstration, we’ve implemented a complete scenario of automatic analysis of 4D Write Pro documents using AI. From a simple text, the AI is capable of:
- Generating a concise title reflecting the content
- Identifying the tone (positive, negative, informative, urgent…)
- Suggesting classification tags
- Evaluating the document’s writing quality
The goal is clear: automatically enrich documents with usable metadata, without changing the user experience.
AI Brings Magical Search to 4D Write Pro Documents
In many 4D business applications, documents are everything — technical notes, reports, manuals, internal guides. But when users can’t remember the exact wording, finding the right one becomes slow, frustrating, or worse — impossible.
With 4D 20 R10, semantic search powered by AI vectors changes that. Instead of matching keywords, you match meaning. Users get the right document, even if they search in different words or a different language. It’s a smarter way to surface the knowledge hidden in your documents — fast, accurate, and built for how people actually search.
Let’s consider a concrete example: a user wants to locate a technical note that explains how to insert an image into a 4D Write Pro document. However, they may not recall the precise phrase used in the document.
Building Forms on the fly with New Data Source Commands
In application development, it is often necessary to build forms dynamically. For example, you might want to generate a search form on the fly, tailored to the user’s needs. In 4D, there are two main approaches for building dynamic forms: either constructing the entire form programmatically or adding objects to an existing form layout. For the second option, until now, it was possible to duplicate objects with OBJECT DUPLICATE, and modify the data source with OBJECT SET DATA SOURCE, all using a classic pointer-based approach.
With 4D 20 R10, new and powerful commands, OBJECT SET DATA SOURCE FORMULA and OBJECT Get data source formula, allow developers to bind a formula as the data source of form objects. Moreover, you can dynamically assign formulas to key listbox properties with the LISTBOX SET PROPERTY command such as Current item, Current item position, and Selected items.
This opens the way to a more modern, flexible and readable approach, thanks in particular to expressions such as Form.xx or the classes.

Restrict data according to privileges or information saved in session storage
In modern application development, securing and finely managing data access are essential. Thanks to the restrict event in 4D, it is possible to dynamically filter the data accessible to a user based on their profile, privileges, and session-stored information.
This blog explains how to leverage this event, particularly in the context of an integration with 4D Qodly Pro, to ensure that only relevant data is exposed.
Designing an Interactive and Dynamic Menu Bar in Qodly application
In this week’s blog, we take a look at navigation. Navigation is a key element of any web application. A well-structured navigation system enables users to quickly find what they need and enhances their overall experience.
With 4D Qodly Pro, managing navigation is both simple and flexible. Using the Page Loader component, you can dynamically load pages based on user actions.
In this article, we will explore how to set up an efficient navigation bar using 4D Qodly Pro. We will use our Performance Review application as an example, which you can download from GitHub (link to be added). We will cover its design, interactions, and permission management to create a seamless experience tailored to each user role.
Customize your Qodly interfaces with CSS
In Qodly Studio, each widget can be styled directly using its properties. However, to maintain a consistent look throughout your application, and to easily apply global styles (such as font color, text size, or the appearance of selections), CSS is your best ally.
In this article, we’ll explore the basics of using CSS in Qodly Studio, with examples from the Performance Review application.
