Synchronization and Replication

Integrated synchronization and replication mechanisms mean you don't need to create your own routines anymore.

Until now, it has been up to each developer to create the mechanisms and workflow for accurate data synchronization and replication, leading to a variety of implementations and, of course, a lot of extra development.

The following sync functions are now integrated:

List Boxes

The list box has long been one of the most useful GUI elements for easily viewing and selecting linear and tabular data.

 

Components

Optimize, share, distribute!

What’s a component?

A component is a library of code and screens that you can drag-and-drop into any of your applications.


Using this mechanism, you can create basic code building blocks, test them, then share them in collaborative development efforts or distributed to your customers.

 

Integrated Database

A powerful relational database is fully integrated into 4D.

4D provides a true enterprise-class database, with the capacity to process massive databases while keeping the same responsiveness and performance you've come to expect in 4D. We've shattered all previous database size limits to give both new and existing databases much more breathing room.


It is up to the challenge of even the most demanding projects.
 

PHP Integration

4D v12 lets you directly execute PHP 5.3 scripts within 4D applications, thanks to our FastCGI compiled interpreter.

(You may use other interpreters, providing they are compatible. See documentation for details.)

 

You get access to a wealth of utility libraries available via PHP, providing functions such as:

  •  ciphering (MD5) and hashing
  •  handling of HTML files
  •  image handling
  •  LDAP access
  •  COM access (for Microsoft Office documents)

 

Printing

4D has always given users excellent control of printing of data from output forms and reports.

4D v12 brings even greater control and variety of print output. List boxes can be printed. The new PRINT OBJECT command lets you print any object at any precise position on the page. And new to Windows, 4D can now print directly to PDF using the PDFCreator driver.

4D SVG

The 4D SVG component is installed with 4D v12, so that all your solutions can take advantage of its advanced graphic capabilities.

The component provides commands to meet your most frequent graphical needs, giving you access to parameters that will let you create your own SVG graphics, or modify existing SVG files from other sources.

 

It includes an SVG Viewer that will let you view your SVG files both as an image and as the XML source code. A separate Syntax Palette lists all of the component's commands - logically grouped by theme - which can be dragged and dropped into your 4D methods, along with all of their parameters.

 

Form Widgets

An entire library of predefined compound objects is included for use in your interfaces.

These include search bars, time pickers, date pickers, barber poles and more.

 

Localization

4D v12 improves upon application localization capabilities.

XLIFF files, used to store localization information since 4D v11 SQL, can now be called upon to change an entire user interface on the fly. A single 4D command can instantly change the interface language.

Dynamic Variables

As of 4D v12, you can now leave it to 4D to create variables associated with your form objects.

If you leave a variable blank, 4D will create the variable and calculate a unique name for it. These dynamic variables can be accessed via pointers, allow the development of subform components, and can economize memory usage as they are only used during the instances when the containing form is opened.
