Customize highlight color upon listbox row selection

A new step is reached to provide our developers with a fully customizable listbox object, entirely adaptable to user need. A new option is available in the listboxes that will allow to improve final interfaces: this option is called “Hide selection highlight”.

With just one click this option can be activated. Once activated, the system highlight will be completely invisible.

Take Control of the Cache Manager

4D v16 introduced a new fully optimized cache manager for the 64-bit product line. 4D v16 R2 is giving power to our advanced 4D developers to take control by themselves!

The cache manager internal algorithm is based on a priority concept associated to each object type to store in the cache memory. By default, the cache manager algorithm assigns a higher priority value for an index than for records. And recently used objects (records or indexes) have a higher priority to remain in the cache than objects that have not been used in the last two days, etc…

Boost your performance with the new cache manager

The 4D v16 version has definitely been designed for better performance and scalability. In addition to major features like preemptive multi-threading, 4D v16 64-bit is embedding a brand new cache manager for a optimized handling of objects in cache memory avoiding any fragmentation issues.

The new cache manager improves the usage of very large cache for modern computers (with 64 or even 128 GB of Cache) allowing to take advantage of low RAM prices to have even large databases fully in memory. It also improves the situation of small cache size with very large data files, by decreasing the amount of unloading memory with increased support of priorities for data objects to be hold or released from cache.

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!

Use Unicode for texts in forms

In 4D v16 the texts for all the form objects (static texts, buttons, check boxes, etc…) will be stored in Unicode, allowing you to use characters from different languages directly in the form editor.

Especially for Asian or Eastern European languages this will ease the development process.
