Quickly jump to different functions of a class

Classes were introduced with 4D v18 R3. They allow you to organize your business logic and separate it from the UI part more quickly.

Classes are composed of several functions of varying lengths, so it’s not always easy to find the function you want to modify, or to move from one function to another. You can use the explorer, which displays classes and functions, but when you’re coding in the editor window, you don’t want to waste time changing windows.

With 4D v19 R4, the list of functions in your class is displayed in the code editor toolbar, allowing you to easily jump to a specific function. 


Simplified navigation between development windows

When writing a new function or method, or when creating a form, the work is never linear. We usually need to:

  • access the explorer to find the form in its folder
  • access the explorer to write the documentation for the method
  • read the documentation of a command on the 4D documentation website
  • read the documentation of a component’s method


In this new version, we have added some menu items in the code editor and form editor to allow you to better navigate between the different elements of a project.


Code Editor: Multiple themes, your choice!

The code editor’s feature set grows with every release, and 4Dv19 is no exception.

Every developer has their own special – and sometimes peculiar – taste when it comes to their code editor (font, font size, color of the elements, etc.). What looks great and boosts productivity for one developer can be an obstacle for another. That’s why 4D v19 introduces theme management.

If “creating my own theme” is on your bucket list, now is the right time to check it off! 4D v19 comes with basic themes that you can enrich and adapt to your own taste.


Code editor: Write more code in less time!

With 4D 18 R4, we announced the availability of the suggested functions for classes (4D and data model). With 4D v18 R6, we’ve got more great news to simplify and facilitate the writing of code in the editor: The prototype of a function and a short description are displayed in the code editor!

Speed up your development process and avoid typos. Now, information about class functions is displayed in the code editor, helping you to write more in less time while making sure that you’re on the right track!

Let’s find out more!


New declaration syntax for an intuitive autocompletion

Have you ever wondered about 4D’s autocompletion feature or asked yourself why 4D suggests all functions used in the code? Since an object is a very generic type, 4D only knows what it’s really storing at runtime. However, that doesn’t help much when you’re writing your code.

4D now offers a new, alternative syntax which will greatly enhance autocompletion when declaring your variables.


Code Editor: Say hello to Comment blocks

Adding a block of comments at the beginning of a method is useful for adding a note about what a method does, as well as a list of input/output parameters. And having a few lines of human-readable text within a complicated section of code can be convenient to help you and others recall the purpose of this particular section of code. Beginning with 4D v18, your programming experience is enhanced with the addition of comment blocks!


Check out the Code Editor enhancements

The 4D Code Editor just got more user friendly! Say hello to character completion for quote marks “ ”, parentheses ( ), brackets [ ], and curly braces { }, as well as command blocks (For…End for, If … End if, etc.). But that’s not all, bracket matching has also been added to help you manage your collections, and the syntax for user methods is now displayed in the status bar just like a 4D command syntax!


4D Methods editor with dark theme

Humans have different taste preferences. For instance, some people prefer white over all other colors, while others find black to be more majestic … hence any new color trend tagged as ‘the new black’!

In order to accommodate different preferences, 4D enables you to personalize the method editor theme!

In the 4D preferences dialog, you can set several parameters for the editor such as the color of the background or each type of code element (i.e., commands and comments). 

Thanks to these different options, you can completely customize the method editor to your taste. Whether you’re a fan of light or dark themes, 4D’s got you covered!

Here’s what a dark theme looks like:


New preferences in Method Editor

You want to visualize occurrences of a given variable in the 4D method editor? Or you find your method code too heavy with all those block icon and lines everywhere that it’s becoming hard to read?

With 4D v16 new preference options are available in the code editor to make the 4D developers’ life easier!!
