Customize App Appearance with New Windows Types
With 4D 20 R5, unlocking new possibilities in application customization, two additional window types now offer flexible modal or non-modal windows without title bars. This means complete freedom to tailor your application’s appearance to your exact specifications. Imagine redesigning the title bar to match your desired aesthetics, integrating features like a customized search box or other elements seamlessly.
But that’s not all! We’ve also introduced several new commands designed to streamline your development process:
- Reduce a window in the title bar on Windows or the dock on macOS,
- Know if the window is reduced in the title bar on Windows or the dock on macOS,
- Know if the window if the window is maximized.
QUIC Now Matches ServerNet Capabilities
The QUIC network layer now supports as many features as the ServerNet network layer. With 4D 20 R5, we added support for IPv6, broadcast, and Single Sign-on on Windows.
Of course, we will continue to improve it in the coming versions to make it the best network layer 4D has ever had.
But for now, let me speak a bit more about the last functionalities we added.
4D Write Pro: Tables without limit!
Since the introduction of tables in 4D Write Pro, many new features have been put in place. Including Headers, footers, sort breaks and, of course, the possibility of associating a datasource with the tables to fill them in automatically!
This last option meant that the maximum number of rows per table (1000) could often be reached. We took this into account and as of 4D 20 R5, this limit is no longer fixed and controlled by 4D Write Pro but only limited by available memory!
New 4D remote session object with Client/Server connection and Stored procedure
In 4D applications, four types of sessions exist 4D Remote session, Stored Procedure session, Mobile session, and Web session.
The Session command already returns Web or Mobile sessions. This gives you access to a wealth of information about the session and an object shared by all processes in the session.
In 4D 20 R5, the Session command has been extended to the Client/Server connection and stored procedure.
ORDA – Restrict Data to Relevant Criteria
In 4D 19 R8, we introduced a robust permission system, granting you granular control over user access to your data. This system protects your data depending on who accesses it and which data is accessed, ensuring data security by restricting unauthorized access.
But what if you wanted to further refine read access based on specific criteria?
That’s where 4D 20 R5 steps in. Restricting read data according to some criteria.
Try-Catch Code Blocks Unveiled!
After implementing the throw() command and introducing the Try(Expression) keyword, we are excited to unveil the next evolution in 4D’s error handling system: the introduction of Try-Catch code blocks!
Shared Classes
Do you want a simplified way to use shared objects, following the classic object syntax and automatically calling use/end use when needed?
Fasten your seatbelts; here come the shared classes!
Singletons in 4D
4D 20 R5 delivers a powerful feature for developers: Singletons!
The singleton design pattern creates a single instance of a class accessible throughout your application.
This pattern offers many benefits, including:
- host for interprocess values,
- utility classes,
- a base for the factory design pattern,
- and many more.

Improved 4D Client Licenses Usage with Qodly Studio for 4D
Those of you who have started using Qodly Studio for 4D already know how powerful this new tool is for developing business web applications. If you haven’t yet, find here more information on getting started.
Apps made with Qodly Studio for 4D rely on the REST APIs. 4D 20 R5 is shipped with a great new feature: “Force Login” mode.
With Force Login mode, a 4D Client license is only consumed when users successfully log in and begin working with your application’s data and logic.

4D Write Pro: More display options for anchored pictures and text boxes!
So far 4D Write Pro documents, pictures can be either in line (just like a big character), behind or in front of the text. Text boxes (appeared in 4D v20) can also be placed in front or behind the text. A huge improvement comes with 4D 20 R5 where pictures and text boxes can now be surrounded by wrapping text!
