At the annual Worldwide Developers Conference (WWDC2020), Apple announced the release of a brand new processor technology called Apple Silicon.
In this blog post, we’ll introduce you to this new technology and tell you about our plans to smoothly transition your 4D applications to Silicon.
Even during the lockdown, 4D continued to foster a sense of community through engaging content, interactive communications, and virtual gatherings such as webinars.
If you haven’t noticed, many of the 4D webinars presented by Will Taylor (Technical Account Manager, 4D US) have been made public on our Youtube channel.
The most recent one is related to 4D Write Pro and how you can create a lightweight email composer:

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.
By now you’re aware of the availability of ORDA classes. In this blog post, you’ll learn a few handy tips to get the most out of them!
You asked for a way to import and export different document formats via the 4D Write Pro widget and once again, 4D listened!
In addition to the 4D commands that already allow you to import and export documents in different formats, such as export .docx format with 4D v17 R4 and PDF format with 4D v18 R4. Now, 4D Write Pro can import and export different document formats via the widget from the toolbar and sidebar.
Interested in building list boxes that can automatically adapt the height of each row to its content so that the full text or picture can be displayed? What about using object arrays in columns (this allows entering and displaying various types of values in the rows of a single list box’s column).
These are very cool features, right? Previously, you needed to have a valid 4D View Pro license in order to use them. Well, not anymore!
4D v18 R4 lets you access these features for FREE! No additional licensing is required, they’re now included in the standard product.
List boxes are powerful form objects. They’re easily created and manipulated, and most importantly, they can handle any kind of data. Additionally, they can be fully set up by programming … everything from inserting or deleting rows and columns, to defining or modifying tons of properties using the 4D language. With 4D v18 R4, another important property has been added to the list. Can you guess which one? Hint: read the title again.
4D View Pro automatically recalculates the formulas in your worksheet when you change data they depend on (e.g., entries, formulas, names, etc.).
But what if you want to make your UI more interactive and trigger the calculation of formulas whenever you want? 4D v18 R4 makes it possible thanks to three new commands: VP SUSPEND COMPUTING, VP RESUME COMPUTING, and VP RECOMPUTE FORMULAS. These commands let you suspend and resume the calculation of all formulas in your document, or force their recalculation.
4D for iOS already provides the ability to build detail forms from the Forms section. Starting with 4Dv18R4, we’ve added even more flexibility for building detail form templates. Here’s how.
Following the ability to use your own end user management system and the SET USER ALIAS command, you might be wondering how you can manage end user permissions without creating multiple 4D user accounts. Keep reading because this feature release has the answer!
