Show online documentation directly from the code editor

In the latest versions of 4D, several improvements have been made to simplify the writing of code with classes:

  • function and attribute suggestions according to type
  • display of the prototype with a short description


With 4D v19 R2, you can open the online documentation of a function with a single action.

Just press the F1 key or click on Goto definition… in the contextual menu



The API classes are documented on the new documentation website. To learn more about the structure of this website and its implementation process, you can read this blog post by Arnaud Schmitt, head of technical documentation at 4D SAS.
