Define the tab order by programming
Here are 2 very common developer needs: 1. Depending on the user criteria, you want to rearrange the objects in the form. – 2. Depending on the selected item in a list, you want to show, hide or move the objects in the form.
In all theses cases, you need to change the tab order of the form objects. Now in 4D v16 R4, you can modify the tab order at runtime by programming. To do so, 2 new commands have been created: FORM SET ENTRY ORDER and FORM GET ENTRY ORDER.
Support of pictures in Objects
From 4D v16 R4, we have added the support of pictures in object attributes. For example, if you use an object to exchange settings or data between methods, forms or processes, now, you can also pass an icon or a picture in this object. You don’t need anymore to temporarily save the picture on disk.
This new type can be used like any other object attribute type: you can use, get and set pictures in objects. You can also use the controls of the picture theme.
New type supported by 4D: Null
4D introduces a new Null type to ease the management of objects and collections. Thanks to the null value, you can represent a missing value and easily verify if your object or collection is correctly set.
4D initiates a new variable type: Collection
4D v16 R4 introduces a new type of variable called Collection. What are these variables intended for? Like Objects or BLOBs, collections can be used to hold almost any kind of variable types like texts, numerics, booleans, objects and even other collections. The good thing is that, all these variables types previously mentioned can be mixed inside the same collection, where arrays must always contain the same type of elements!
Easily design your own 4D Write Pro toolbar with standard actions
You need a custom 4D Write Pro toolbar for your application but you’re concerned it might take too much time to implement it? Good news, with 4D v16 R4 standard actions can now be assigned to checkboxes and pop-up menus. Save time with this ready-to-use feature and easily create a user-friendly interface perfectly matching your needs!
You can now create a pop-up menu to control the font size or the border style for your 4D Write Pro area just in one click, no code needed! Just assign the action using the property list and it’s done. And the object status and value will be automatically updated by 4D depending on the context and text selection! Simple and powerful…
Validate your JSON object
We use more and more the JSON format. For example, to save settings in a file, to store software configuration, or to exchange client-data on the web with other servers.
How can you validate that the received data is in the expected format? How can you validate that all the necessary information is actually present? How can you do this validation without writing a tiresome method for each type of JSON format?
Simply by writing a JSON schema and use the JSON Validate new command!
4D introduces SDI mode for applications on Windows!
Hot news! 4D applications on Windows are entering a new world thanks to 4D Windows 64-bit. Do you remember the grey-background main window which contains all other application windows? This main window is technically called MDI (which stands for Multiple Document Interface) and now there’s a way to get rid of it and move to SDI (Single Document Interface) where application windows are all independent…
Interested? Just activate the SDI mode with a single checkbox and it’s done…without a line of code!
The complete Windows 64-bit product line is now Altura-free
We are pleased to announce that 4D v16 R4 is the very first version where the whole 4D Windows 64-bit product line is no longer relying on the Mac2Win library from Altura! As announced in last April, in this strategy announcement post, we have done the work on 4D Server Windows 64-bit, which was the last step to reach.
Our Windows 64-bit product line can now fully take advantage of some modern technologies and make you benefit from it, such as support of Single Document Interface (SDI) windows for instance, also delivered with 4D v16 R4!

After the advanced list usage completely covered with 4D v16, 4D v16 R4 reaches a major step toward with 4D View Pro by providing our customers with the first step of our 4D View Pro spreadsheet solution, provided as a preview.
Add an hyperlink to your company logo in 4D Write Pro
A less well known usage of 4D Write Pro product is the production of HTML emails. In fact you can create a 4D Write Pro document including 4D expressions, text and images, then modify the document, paragraph or text properties and send it by email. In this context, a very common need is to add a link to a picture, e.g. your company logo.
