Automatic Row Heights in Collection Based List Boxes
List boxes are the most versatile and customizable form objects. Automatic row heights were already possible for array-based list boxes. With the arrival of 4D v19 R8, this possibility is now extended to list boxes based on collections… and entity selections!

Here we go with another set of tips and tricks.
As you know, 4D Knowledge Base is a library of information about 4D technology where weekly tech tips and monthly tech notes are actively published. If you missed the last tips on the KB, that’s fine; here is a compilation from the past few weeks.

LIST BOXES: More Control. More Beauty!
List boxes are powerful and very customizable form objects. And their power is extended with 4D v19 R6 thanks to two new properties: horizontal and vertical padding (the inner margins or the space between an element’s content and its border). They will give new presentation possibilities to your list boxes, and an even more professional appearance to your interface,
New Windows system rendering engine for Web Areas
Web areas can display various types of web content within your forms: HTML pages with static or dynamic contents, files, pictures,… You can choose between two rendering engines for the web area, depending on the specifics of your application:
- the embedded rendering engine
- the system rendering engine
The advantage of the embedded system is the cross-platform portability. No need to adapt to some specifics of a platform. Moreover, it allows you to access 4D methods.
The advantage of the system browser is the security updates that are available right away. There’s no need to wait for the next version of 4D. We recommend it for accessing the public Internet site.
Windows has announced that “Internet Explorer 11 is retiring on June 15, 2022“. So since 4D v19 R5, if you use the system rendering engine, 4D uses Microsoft Edge WebView2. This change allows you to benefit from a modern browser with the latest features and security updates. For example, Microsoft Edge can be used to display PDFs.
ORDA – Optimize performance with full control over REST requests
With a previous version, you discovered how ORDA REST requests had been automatically optimized to increase performance when working with a remote datastore and client/server configurations.
You learned that you can use contexts to take advantage of the automatic ORDA REST requests optimization.
That was a significant step, but now we offer to have complete control over the behavior of your REST requests. Since performance is a strategic concern, you must be eager to discover this new feature!
And that’s not all; new tools are now available to help you understand and debug your issues.
