Vanessa Talbot joined 4D Program team in June, 2014. As a Product Owner, she is in charge of writing the user stories then translating it to functional specifications. Her role is also to make sure that the feature implementation delivered is meeting the customer need.

Since her arrival, she has worked to define key features in 4D. She has worked on most of preemptive multi-threading new features and also on a very complex subject: the new architecture for engined application. Vanessa has a degree from Telecom Saint-Etienne. She began her career at the Criminal Research Institute as a developer for the audiovisual department. She has also worked in media and medical fields as expert in technical support, production as well as documenting new features.

SVG “non-scaling-stroke” attribute support

Automatically translated from English

Sometimes it’s preferable to have the lines of an object keep their original width, regardless of the applied transformation. For example, you draw a line on a map showing a user’s position and a destination. When the user zooms in on the map, you want to enlarge the map but have the line maintain its width.

Code Editor: Say hello to Comment blocks

Automatically translated from English

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!

Project database: Deploying your application

Automatically translated from English

So your application has been developed and you’re ready for the next step. 4D lets you:

  • generate a compiled database that no longer contains any interpreted code,
  • generate a standalone application that can be double-clicked, (i.e., merged with 4D Volume Desktop, 4D’s database engine),
  • generate client/server applications with automatic updates of client and server parts.

 

With a project database, you can also build your final applications for both platforms. A project database uses the same configuration file as a binary database.

Project Databases: Post conversion

Automatically translated from English

In this blog post, we showed you how to convert a binary database into a project database. Once everything is ready and the conversion has successfully completed, you can start working with your project database. However, some questions may arise: are all the files in the database useful? It’s obvious that the”.4DB” structure file is no longer needed. Can I delete other files?

Here’s everything you need to know after the conversion.

Project databases: beautify your forms with style sheets

Automatically translated from English

Classic 4D binary structures let you define style sheets to specify the font, font size, and text style to use in your forms for both the macOS and Windows platforms. Project databases let you go even further by letting you define the properties of a 4-state button or specify the color and border of all line objects or even set the header height of all of an application’s list boxes! Inspired by the grammar and syntax of CSS, 4D adapted it to meet the specific needs of the forms in 4D project databases. Thanks to style sheets, you can configure all of the properties to create truly visually appealing forms. This blog post shows you how!

Project databases: Architecture

Automatically translated from English

Project databases, the headliner of the 4D v18 release, allow distributed teams to work collaboratively by storing an application’s code in a source control system, in text files containing everything from the database structure to the user interface, including forms, menus, user settings, or any required resources. And since a project database is made of text-based files, you’ll have several folders and files, stored within a single parent database folder. In this blog post, we’ll go through the architecture of a project database to give you a better understanding of this new type of database.

Project databases: More than a collaboration solution

Automatically translated from English

Dreaming of a way of to work collaboratively? A way to work wherever you are in the world, with team members in different locations, and no one has to question where to find the latest version of a file or project? A different way to test new features and roll them back if they don’t work out, while being able to choose a restore point from which you want to roll back instead of running a full file backup. Your dreams are becoming a reality, these scenarios are now possible thanks to 4D v18 and project databases!

Power of objects and dot notation

Automatically translated from English

With 4D v17 R5, we showed you how easy it is to manipulate an object to retrieve the attributes of a file or folder. Things have gotten even easier thanks to object notation! In this blog post, we’re providing you an HDI with a user interface to manage files and folders. This isn’t new in 4D since you could do it with classic 4D commands, but now you can do it easier and with fewer lines of code!
