4D for Mobile Tutorial – Sort your list view
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.
4D for Mobile Tutorial – Define filter queries
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.
4D for Mobile Tutorial – Your first application
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.

Create your Native Mobile Application with 4D
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.
This blog post is a compilation of features available in our mobile solution that enables you to build a complete app that goes all out!
A Tailor Made Native App: Place Orders with 4D for mobile
4D v19 R6 and v19 R7 brought two interesting features to 4D for Mobile. Sessions and displaying web pages served by the 4D server in your native mobile app. But did you think about the possibilities you get when combining them both?
This blog post will show you one of these possibilities. We are going to see how to build a simple app that enables mobile users to place orders with their central purchasing office to consolidate their stock:
4D REST API + ReactJS
by Mourad Aouinat, Software Engineer at 4D Morocco
In a previous blog post, we saw how easy setting up a REST API using 4D. In this blog post, we will leverage the powerful 4D REST API in combination with React to build a To-Do app that includes features to open todos, create new ones, modify existing ones, and features for bulk modification and bulk deletion.
How to connect Tableau with 4D
In 4D Webinar – How to Connect Tableau with 4D, William Taylor (Technical Account Manager, 4D US) gave an overview of the Tableau tool and how it could be used to visualize your 4D data. In this blog post, we’ll dig into the technical details to give you a deeper understanding of how it works. This will allow you to build, for example, a visual showing the highest invoice total with nothing more than 4D REST and Tableau!
How to create a simple “TimeStamp” class in 4D
by guest author Tiran Behrouz, 4D developer (Vancouver, Canada)
The introduction of ORDA in 4D v17 was a game-changer. Now with the introduction of classes in 4D v18 R3, we will witness a paradigm shift in 4D programming. We can now take advantage of object-oriented programming concepts such as polymorphism, composition, and inheritance to write our own class libraries. In this video, I demonstrate how to code a simple TimeStamp class using 4D and ORDA.
An enhanced UX with AJUI_Progressbar
Have you ever executed an action, nothing seemed to happen, and you didn’t know if you should click again or continue waiting? There’s no feedback provided, even if the application is performing an action in the background? Perhaps the action requires some time to return a result? As you may know, 4D already provides a built-in progress bar component that makes execution time more tolerable, but if you want something with a more web like design then keep reading, because that’s what the AJUI_Progressbar gives you!
AJUI_Tip: A tooltip engine for 4D
Have you ever been flooded by confirmation dialogs, alert boxes, and contextual help windows that make it nearly impossible to locate the form window on which you were working? Wouldn’t it be more user-friendly to stay on the same page and see help bubbles pointing directly at the original target?
This is possible thanks to the 4D component AJUI_Tip. It’s a powerful tooltip engine based on the technologies available in 4D such as ORDA, New Formula, SVG, SubForm, CALL FORM, to name a few. In this blog post, we’ll highlight the component’s usage, and show how you can design beautiful tooltips to enhance your applications’ UI. A download link can be found at the end of the blog post.
