Exchanging messages between processes

4D v15 R5 introduces a new, simple and powerful way to exchange information between processes and also between processes and forms. This feature is based upon an asynchronous messaging system that allows processes and forms to be called and asked to execute methods with parameters in their own context.

Product 4D Windows 64-bit: Altura free

Altura-free version of 4D Windows 64-bit is on the way

On the way to provide Windows 64-bit version of the 4D product line we reached a major milestone, an Altura-free version. Altura is a library to emulate MacOS functionality on Windows, which was used to help plug-in developers to provide their products on Windows.

Although internally 4D for the most part did not use Altura any longer for a while, it was still deeply integrated to provide the functionality for 3rd party plug-ins.

Product 4D View Pro: Variable Row Height in Listbox

4D View Pro – Variable Row Height in Listbox

Displaying a list where the line height would exactly fit the content is a very common need. 4D View Pro is including a new feature so that you can now control the height of each row independently in a listbox to make it fit to its content. To know more about 4D View Pro, check out this blog post.

There are actually now two ways to define the row height in a listbox:

  • using new dedicated commands
  • using a new control array

4D Write Pro commands in preemptive processes

With 4D v16, you can improve your database scalability using the new 4D Write Pro commands in preemptive processes.

If you are doing routines for creating or converting documents programmatically – e.g. invoices … you can now do it with preemptive workers as most 4D Write Pro commands are now thread safe!

Product Listbox resizing

Listbox – columns AUTO resizing !

4D v16 includes a new feature providing your end-user great freedom and flexibility at the interface level when using list boxes. The constraints defined for each column are now fully applied and respected when the list box they belong to is resized.


New commands to save and restore print settings

This feature allows users to save and restore print settings (even those that cannot be set using 4D Get print option and SET PRINT OPTION commands) quickly and efficiently, whether on Windows or Mac OS in both 32 and 64 bits environments.

Office printers supports a large set of features, duplex, staple, punch, watermark, ink saving, color calibration, just a name some. The new commands BLOB to print settings and Print settings to BLOB supports to save and restore the whole set of information available via printer dialogs, allowing fully automatic (and faceless) print jobs.


Execute action upon listbox column resizing

The event On Column Resize is now triggered “live” during the resizing of the list boxes as long as the user modifies the column widths (previously, it was generated only once, at the end of the resizing).

Thanks to this feature, 4D programmers will have the opportunity to create live and responsive interfaces based on the actual width of columns!


Headers and footers in 4D Write Pro

4D Write Pro is moving forward with 4D v16!

You can now insert headers and footers in your 4D Write Pro documents but also retrieve any existing headers and footers when opening an existing .4w7 document from the 4D Write plugin.

You can define document sections and add headers or footers for all or independently per section. You can have different headers/footers for the right and left page, or for the first page of the section. Of course, headers and footers can be styled as the rest of the document (font, color, margin, padding, borders…) and can contain images as well.


Insert in-line pictures in 4D Write Pro documents

You want to insert your company logo in the signature of all your 4D Write Pro documents when they are being created? Or you want to add a product image for each of your invoices lines?

With 4D v16, it is now possible to insert inline pictures programmatically in your 4D Write Pro document with the dedicated command WP INSERT PICTURE!
