Starting with 4D v16, you can set a different row height for each row in your list box. So with a few lines of code, you have a list box with rows that conform to the content. With this 4D v16 feature, we gave full control to the developer to precisely define the height for every single row of the list box.
With 4D v16 R5, we’ve decided to go further, and provide you with a fully automatic mode. It’s now possible to display lists in a gorgeous interface without any programming. You only need to set a few properties in the list box, and 4D does the rest for you. It’s magical, fluid, and again … not a single line of code!
Today, big screens are everywhere. At the airport or train station for arrival/departure. In production areas for failure/success or production numbers. In call centers for activity or calls in queue. In stock exchange for a ticker.
Your first thought could be to use a normal computer, macOS or Windows, with a “27” or 30” screen. Expensive, but easy to do. But besides the high price, you need to run a 4D app, launch it, update it, all just to display a picture?
According to neuroscientists, we respond better and faster to a visual form than any other type of representation. That’s why graphs and charts are clearly a key to a better understanding of data.
So if you’re looking to display bar charts, histograms, or pie charts which are modern and fully compatible with the leading browsers, but also more suitable for the way the human brain processes information, Google Charts is one possible answer. The available chart types in Google Charts is varied: from the classical bar/column/pie charts, Google Charts also offers elaborated graphs such as Treemap, Candlestick and Gauge charts.
4D v16 R4 is providing you with more flexibility regarding tips management. Beyond the possibility to enable or disable all tips at once using database parameters, you can now finely control how your tips will be displayed: the delay before showing it and for how long it is shown. And you no longer need to use 4D Pack, everything is included in 4D now!
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.

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!
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.

4D Write Pro has been enhanced with 4D v16 R4 so that hyperlinks can now been added to text and/or pictures. Setting a link to your company logo or company name is now as easy as styling some text to bold.
4D gives you new possibilities to customize your 4D Write Pro user interface to make it perfectly fit your business application. Instead of using the default 4D Write Pro contextual menu, which is so detailed that it could become unpleasant to use, the 4D developer can create its own contextual menu, with the exact list of actions that he wants to provide.
