Year in Review: Top Five Features From 2022
2022 has had four product releases loaded with the many features you requested.
While it was challenging to pick only 5 features from the ever-growing list of functionalities, we have collated this list of the top features of 2022 based on the positive feedback we’ve received.
VS Code: Go To Definition & Signature Help
4D v19 R6 brought the support of external source code editors (e.g., Visual Studio Code), allowing them to handle 4D code and provide them with standard functionalities such as syntax highlighting using the Visual Studio Code extension.
4Dv19 R7 brings two new capabilities: Go To Definition and Signature Help.
Say Hello to Rounded Corners
The current trend is for light, clean, soft colors and rounded corners.
For you to embellish your applications and follow the latest trends, we have added the possibility to round the corners of static texts and input texts.
Latest Improvements of the HTTP Client
With 4D v19R6, we brought you a new way to perform HTTP requests: HTTP classes. At that time, some of the HTTP classes functionalities were not final, as we wanted to adapt them to the new syntax. It is now done! In v19R7, compressed responses, chunked responses, and redirections functionalities are now complete.
As a bonus, we also added a new way to log HTTP requests. And as it’s helpful to everyone, this new logging is available to the new HTTP classes as well as for the legacy syntax.
Files, Folders… and now File Handles!
The File and Folder commands, which appeared in 4D v17 R5, enable you to manage folders and files on disk in a modern and efficient way.
When it comes to writing and reading, the setText and getText functions are at your disposal to read or write the entire content. But what to do if you want to read or add one or more lines to an existing document? This can be done more efficiently than ever using the new “file handles” objects in 4D v19 R7.

HTTP classes: A New Way to Perform Asynchronous HTTP Requests
In our constant effort to improve 4D syntax and functionalities, we have decided to bring you new commands to perform HTTP requests in 4D: the HTTP classes. They are available right in 4D v19 R6 and will feature many improvements over the coming versions. Let me show you how to use them right away.
LIST BOXES: More Control. More Beauty!
List boxes are powerful and very customizable form objects. And their power is extended with 4D v19 R6 thanks to two new properties: horizontal and vertical padding (the inner margins or the space between an element’s content and its border). They will give new presentation possibilities to your list boxes, and an even more professional appearance to your interface,
Form and subform communication made easy!
Starting with 4D v19 R5, the ability to associate a variable with a subform has enriched the possibilities of interfaces and communication between forms and subforms. The means of communication are now simplified by two new commands: Say hello to OBJECT Get subform container value and OBJECT SET SUBFORM CONTAINER VALUE.
A Seamless Way to Manage Parameters
In the declaration of a function or method, you explicitly define its parameters. Then, when calling that function or method, you can pass fewer parameters to it if some are optional. Or, if you used the declaration with ${n}, the number of passed parameters is variable. In this case, you use the Count Parameters command with a loop over the arguments. This code works flawlessly. Still, it’s a little bit heavy.
You asked us for a lighter way to handle parameters, and we listened. Starting with 4D v19 R5, we provide you with a new command, Copy parameters, allowing you to write a seamless, more elegant, and easier-to-read code.
More options for object set enterable command
There is a multitude of interfaces and rules to be respected. Often, these constraints are linked to the domains of activity. Obviously, some data can be entered or not by the user. For a field that is not enterable, there are two ways of managing the interface:
- users can still select and copy its content, for example to add it to a report
- users are not allowed to copy the field or select its content
