An enhanced UX with AJUI_Progressbar

Automatically translated from English

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!

An ORDA Cheat Sheet

Automatically translated from English

Blog post by guest author Cannon Smith, a 4D developer from southern Alberta, Canada: 

The introduction of collections and entities has dramatically changed the landscape in 4D, giving developers new ways to map business rules to code. Just recently I refactored several thousand lines of code that were central to the business rules of our application, resulting in a significant speed improvement (5xs faster) which our users are very happy about. This refactoring was largely about moving from old code constructs to objects, collections, and ORDA.

Thoughts and reflections on 4D World Tour 2019

Automatically translated from English

Blog post by guest author Kirk Brooks, a 4D developer from San Francisco: 

Visiting 44 cities around the world to bring all the latest 4D developments, 4D World Tour 2019 finally arrived in Atlanta on April 8–9th 2019. The two-day event featured sessions and workshops with the 4D team. For me, this was the best World Tour so far . . . and I’ve been to them all!

The first day is free and in previous World Tours, day one was more of a sales pitch and feature overview. Not this time! There were 17 demo databases to highlight and present many of the new capabilities involving ORDA, Form, dynamic forms, and a more refined preview of 4D for iOS. There were a lot of useful elements you can pull right into a project.

AJUI_Tip: A tooltip engine for 4D

Automatically translated from English

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.
