Tableau and 4D: Deploy your WDC to Github Pages

Automatically translated from English

In the  How to connect Tableau with 4D blog post, you learned how to create a web data connector (WDC) to request data from 4D and visualize it in Tableau Public.

Now it’s time to host our WDC! Since it only uses HTML and JavaScript files, Github Pages is the best option to store them. This allows others to test your connector directly in their Tableau software. In this blog post, I’ll show you how to proceed.

Bonus: I’ll also show you how to debug your WDC in Tableau Public using Chrome. Let’s get started!

How to create a simple “TimeStamp” class in 4D

Automatically translated from English

by guest author Tiran Behrouz, 4D developer (Vancouver, Canada) 

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.

Pro list box features are now FREE!

Automatically translated from English

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: Setup movable rows (or not!) by code

Automatically translated from English

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.
