4D for iOS: Sort criteria and action parameters enhancements
4D for iOS gives you the ability to define actions that automatically call a 4D method linked with an event on the smartphone. For example, using them, you can execute 4D code, manage and edit your app’s content using parameters, and, more recently, sort your app’s content easily using sort actions!
Defining sort criteria and action parameters has been improved to make things easier and help you work more quickly and efficiently.
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.
4D for iOS: Easily interact with Apple Native apps
With 4D for iOS, we are always thinking about mobile-friendly features. The primary purpose is to help developers provide the best user experience for their mobile applications. And that’s why, with 4D v19 R3, we’re shipping action input controls.
LZMA: The new compression algorithm
Whenever we exchange files, we always go through the ritual of compressing the files before sending them. Since 4D v18, two commands are available, allowing you to create and read a ZIP archive using the standard zip compression algorithm.
With 4D V19 R3, the Zip Create Archive command supports a new compression algorithm: LZMA. The advantage of this algorithm is that it creates smaller archives than the standard zip compression algorithm. Let’s find out more!
Simplified cross-platform client/server application building on Windows
The release of Silicon Macs had a great impact on the way 4D compiles applications. Before v19, 4D was compiling only for Intel architecture, using the same code on Mac and Windows. But Silicon Macs use a new architecture, and as such 4D needs to compile specifically for Silicon. It affects cross-platform client/server application building.
As long as you build your server on Mac, it’s not much of an issue, as you can compile for both Intel and Silicon platforms. But on Windows, it’s not possible to compile for Silicon Macs. Our current recommendation is to compile the project on Mac for both architectures, and then copy it on a Windows machine before building the server. Unfortunately, for big projects with a lot of data, the copy can take some time.
Need a magic wand? Here are computed class properties!
A magic show awaits you with ORDA’s computed attributes!
It is often helpful or even essential that databases be adapted in a flexible and evolving way to users and their businesses in the computer world. The control of accessible data is also a recurrent and sensitive subject. From this point of view, developers use methods and formulas that are sometimes complex to give or restrict access to information, depending on the context or the access rights of the users.
Let’s take a simple example. In your application, you sometimes need to display a list of people. One of the columns displays their full names, but in your database, you have a first name field and a last name field. Currently, you write a formula in the list box column, and you have to manage the sorting on the column yourself. Wouldn’t it be great to have a computed field where you can define its calculation formula and sorting method, and have all the business logic inside the class and not in each interface?
Well, starting with 4D v19 R3, 4D provides a solution to this, with computed attributes.
Webcam support in Web Areas
With COVID-19, the remote office has become a new standard, and video conferencing is becoming commonplace for professionals. As a result, more and more professionals have started weaving video conferencing features into their applications. To allow you to display video conferencing from different sources like Zoom, Microsoft Teams, and others, we now support audio and video streams in web areas!
4D for iOS: Custom Input Controls
Until now, custom formatters allowed you to match text or images to the contents of a field, such as replacing true/false with an image or 1, 2 with text labels. 4D v19 R3 allows you to create action input controls available from actions forms, such as creating a choice list with predefined text. And even better, this list can be dynamically filled using a datasource such as a list of employers. Let’s delve into the details!
4D Write Pro – Continuous Section Breaks
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!
