List boxes: Manage clicks in edited cells

As a developer, you’re used to handling events inside form objects. The most common is the on clicked form event which can be used in most objects, including list boxes. In this particular object, clicks can be managed either at the list box level itself or within the column methods.

And starting with 4D v18 R6, the on clicked form event is triggered whether a cell is being edited or not, giving you increased control and improving the interface.

4D Write Pro: Decimal point or comma for number alignment?

Numbers … big, small, very big, very small …  No matter their size, it’s always better if they’re easy to read. In most countries and languages, separator characters are usually used to separate thousands (or tens of thousands) and there is always a character to distinguish the decimal part from the rest of the number. When it’s time to align these numbers correctly in documents, “decimal tabulators” are used (which are based on the decimal separator character of the numbers).

But what if the documents contain numbers from different countries and the numbers aren’t formatted in the right way? Let’s take a closer look at this!

Multiple web servers in a single 4D instance

Have you ever needed to use multiple web servers in order to, for example, split your web application code into several business units, or separate the administrator’s web server from the user’s or run an old part, not preemptive-ready yet, in a separate instance, allowing the main part to run preemptive?

If you’re nodding your head yes, then keep reading because 4D v18 R3 allows you to do so … with ease.

4D Write Pro documents: a useful new parameter

4D Write Pro has been designed to create all kinds of documents, from the most simple to the most sophisticated. To achieve this diversity, documents can hold distinct parts, like paragraphs, sections, headers, footers, etc. Once filled in, 4D Write Pro behaves in such a way that all of these parts can be read. However, sometimes some parts must be resized according to their content. This is typically the case for headers and footers whose height can change automatically. This functionality is generally very useful, but sometimes it’d be more practical to set the heights of headers and footers to constant values (even if their content may be truncated and no longer be fully visible).
