Another way of coding: Object notation

Automatically translated from English

Objects are great, everyone says so. Beside their wonderful flexibility, they are unbelievably fast. You can search through millions of records in just a fraction of a second. 4D v16 even allows to order by object attributes, and to do calculations such as Sum or Average.

With 4D v16 R4, the 4D language has been drastically enhanced to make the usage of objects much more comfortable – with the support of the object notation. Fast, flexible, efficient and now elegant!

Get ready for Object Notation

Automatically translated from English

You are looking forward to start coding with Object Notation? For sure, Object Notation will make your life easier as a developer. But before activating it in your existing application, you should make sure that your code is ready.

The new Object Notation syntax introduces some restraints as 4D language now considers the three following characters as reserved symbols: “ . ”, “ [ ” and “ ] ” (i.e. dot, opening and closing brackets).

As a consequence, once you have activated the Object Notation in your database, it is no longer allowed to use these symbols in variable names, method names, table names, or field names. And of course it is the same for your existing code!

So it is important to check that your application does not contain these symbols before activating this feature. But don’t worry the MSC can do it for you!

Source code sharing of internal 4D components with 4D Partners

Automatically translated from English

4D has initiated a new program to share the source code of internal 4D key components such as the 64-bit Quick Report, the date/time pickers, or even the 4D Write Pro user interface.

Sounds already interesting, but what exactly does it concretely mean for you? You always wanted to use the Time picker widget, but with a different look and feel. The 4D Write Pro user interface is great, but can’t fit exactly in your application, that is requiring a more ‘Microsoft Office like’ ribbon bar approach.

Tips Design your menu in 4D Write Pro

Create your own contextual menu for 4D Write Pro

Automatically translated from English

4D gives you new possibilities to customize your 4D Write Pro user interface to make it perfectly fit your business application. Instead of using the default 4D Write Pro contextual menu, which is so detailed that it could become unpleasant to use, the 4D developer can create its own contextual menu, with the exact list of actions that he wants to provide.

More standard actions for Styled Text areas

Automatically translated from English

You want to quickly create a toolbar for your Styled text areas. You want to change the font of the text or compute/freeze 4D Expressions without writing a line of code. It is possible using the new standard actions for Styled Text areas.

Just associate a standard action to each button object and 4D will handle everything automatically: action triggering but also the button activation or deactivation if the action is not available in the current context.
