4D Write Pro – Continuous Section Breaks

Automatically translated from English

Starting with 4D v19 R3, 4D Write Pro supports continuous section breaks.

A continuous section break creates a section in its own right but without causing a page break.
This allows, among other things, to have different numbers of columns on the same page!

Stop press! Accessing parameters not being passed is … possible

Automatically translated from English

A method or function can have optional parameters. Sometimes the function is called with two parameters, and other times with three parameters. We’ve all dreamed of accessing the parameters without counting the parameters, checking if the parameter has been passed, or simply not having to check if the variable associated with the parameter has been initialized. This could make the code much simpler, and much more readable, without all the “If” or “Count parameters” lines.

Well, dream no more, and switch to 4D v19 R3! Managing method and function parameters has never been easier.

4D for Mobile: What’s new in v19 R3

Automatically translated from English

We are pleased to announce that a new version of 4D is available with new features for 4D for iOS and 4D for Android.

WHAT’s in it?

For both 4D for iOS and 4D for Android:

 

For 4D for iOS only:

  • You can create action input controls of type choice list. The choice list can be a predefined list in a JSON or a dynamic list filled using a data source.
  • In your actions and input controls, you can use computed attributes to simplify your code.

 

For 4D for Android only:

  • The N to one relation is available, so you can display relative data in a list, and decide which field(s) from the related table to publish in your app
  • You can test and debug the generated application on your device.

 

Several blog posts detailing the different features are listed in this post.

Automatically translated from English

We’re pleased to announce the launch of beta testing for 4D v19 R3! One of the richest feature releases we have shipped so far!

Without further ado, let’s take a look and see what this feature release has in store for you:

 

  • Your business logic will love 4D’s new Computed Attributes in ORDA, Classes, iOS, and Android.
  • 4D for iOS with features allowing to interact with native Apple apps and build even more advanced UI’s. 
  • As for 4D for Android, we’re giving you a way to test your Android app on a real device before releasing it to users.
  • 4D Write Pro is shipped with an image setting dialog, the possibility to have different numbers of columns on the same page with continuous section breaks, and additional options to manage formula visibility. 
  • Out-of-the-box security boost with the support of the bcrypt algorithm for passwords. What’s best, there’s nothing to change in the code. Everything is automatic. 
  • More news for dark mode enthusiasts. After giving end-users a choice between dark and light mode for the appearance of their applications, it is now the turn of developers to choose between these modes during development on macOS.
  • And more (see below)!

An introductory guide to 4D and Version Control Systems

Automatically translated from English

For many years, 4D has allowed you to develop binary databases as part of a team with a 4D Server. This way of developing is straightforward, but many developers asked us to be more efficient on source code management to deliver better traceability. 4D has heard them and developed Project mode to fit this need. This mode opened a new era of collaboration thanks to version control systems!

Automatically translated from English

We’re pleased to announce that 4D v19 R2 is now available!

Here’s an overview of what this feature release has in store for you:

Download 4D v19 R2 

  • 4D for Android (our development platform for Android devices) is now final with 4D v19 R2. 
  • Speaking of mobile, new features for iOS and Android platforms are now available, allowing you to customize your app’s color, adapt it to dark or light mode, sort its local data, and more! 
  • 4D View Pro: Analyze data with pivot tables. Import and export CSV files. Manage your sheets by programming. Easily handle page breaks (for printing purposes) from the user interface.
  • 4D Write Pro: More display options for inline and anchored pictures. We’ve also made it easier to format the images as background documents, sections, paragraphs, etc.
  • More Object-Oriented programming features that will please your developers. Beyond the storage aspect, memory management and speed performance will be significantly enhanced with blob content for object attributes.
  • Features that incorporate best practices such as defining a default .gitignore file and managing Byte Order Mark (BOM) and End of Line (EOL).
  • Features that enhance your experience as a developer, such as getting access to the details of a class function from the code editor.
  • Features that make the end-user experience smoother, such as automatic component signing on Mac.
  • And if you’re a software publisher, you’ll be happy to know that we’ve added a feature that prevents the users of your application from seeing (and modifying) the contents of the 4DZ.

How to define sleeping timeout for remote 4D applications

Automatically translated from English

To prevent session loss, 4D monitors the sleeping state of remote 4D applications.

When a user is connected from a remote 4D application to a 4D Server and their computer goes into sleep mode, the information is sent to 4D Server. At the moment the user’s computer wakes up, the remote 4D application then recovers its execution context.

Secure your app’s resources with a new algorithm

Automatically translated from English

When generating .4dz files, 4D uses a standard zip format by default. If you are a software publisher, you’ll be happy to know that 4D v19 R2 added a feature that allows preventing users of your application from seeing the content of the 4DZ, and therefore from being able to modify it.
