4D v19 R8, the last feature release of 4D v19 is OUT!
Here’s an overview of what this feature release has in store for you:
- Protect your data from unauthorized users with a robust and fully customizable system by deciding who is accessing the data and which data is accessed.
- Design gorgeous interfaces with the automatic row height feature that is expanded to list boxes based on collections and entity selections.
- Create more compliant documents with 4D Write Pro floating text boxes.
- Build your own chain or integrate 4D into a continuous integration tool thanks to the new Build4D component.
- Handle errors more effectively with a global error handler — no more error dialog displayed on the server and no more uncaught errors.
- Receive, copy, move, reply, and delete emails with the added commands to the 4D Netkit component.
- Customize your 4D View Pro tables with over 60 predefined themes, or create one from scratch to suit your needs.
These are just a few features you can expect to see in 4D v19 R8.
It’s an exciting time for 4D developers, and we can’t wait to see how these new features will help you in your development work.🙌

Formatters allow you to format the displayed data or to define behavior when the user touches the data. The input controls follow the same principle. They allow you to select the type of keyboard, define the behavior, or format the data in an action form.
For example, for image data, you have by default two types of control, the first one allows you to select an image or to take a picture, and the second one displays a zone to sign.
There are 3 types of input controls:
Actions allow users to interact with the application to change the customer’s address, add a new contact and modify a picture.
In the 4D language, an action allows you to add, edit, and delete an entity or a selection entity. But also, it can simply execute a method of your 4D server.
In this blog post, we will show you how to include relations. With 4D for Android and 4D for iOS, you can easily navigate between your related data. We automatically generate the transition between views in your application.
A data formatter allows you to map a data type from your database to a specific display on the mobile side. For example, you can define a date, percentage, or currency format. Data formatters can also call some code to create intelligent interfaces.
For example, you can attach a data formatter to phone numbers that open an action menu on the mobile app when the user touches the number (e.g., to call the person or save them in contacts).
You have three formatter types:
To facilitate the use of an application, the data presented to the user is usually sorted alphabetically, chronologically, or a combination of several criteria.
4D for Android and 4D for iOS allows you to define multiple sorts for each list view.
Error management is often a constraining part of development in all languages. In 4D, if you forget to call an error-handling method in a new process/worker or use components that don’t handle errors, the built-in 4D error dialog can appear to the final user. 4D developers would like to catch all errors in all contexts to avoid displaying this built-in 4D error dialog.
Let’s see how we can manage this behavior with 4D v19 R8.
For a mobile application, data is usually filtered to preserve storage space and provide direct and quick access to essential data.
With 4D, you have two types of filters.
- A static filter to filter the data for a table. For example, limit to tasks with the status ‘in progress.’
- A dynamic filter depends on the user’s information. For example, return only the user’s tasks.
This tutorial will show you how to use and combine these two filters.
The 4D mobile application generator allows you to create mobile applications for Android and iOS. In the documentation, you have several tutorials to help you get started and even go further with advanced apps.
The first example is simple and allows you to create a contact catalog. All the details can be found here.
And if you prefer, here are all the steps in the video:
4D for Android and 4D for iOS allow you to configure, design, build, and deploy native Android and/or iOS apps based on a 4D database. Once generated and deployed, mobile clients can connect to the 4D Server and interact with new or existing data without additional requirements.
4D for Android and 4D for iOS are included in a single integrated 4D component. You can create a mobile project and decide to build it for Android, iOS, or both.
4D handles the complexity and generates an Xcode project in Swift or an Android project in Kotlin. Then, you can reopen them with Xcode and Android Studio and continue to work on them.
