4D Write Pro: Save the view properties

Automatically translated from English

View settings are used to define how a document should be displayed. Until 4D v17 R5, these settings could only be modified using the contextual menu or standard actions. Now they can also be set and get within an object using new commands, as we explained in this blog post. But you can do even more, because these settings can be saved and re-applied afterward! You’ll definitely appreciate having your settings saved!

Substitute missing fonts in 4D Write Pro documents

Automatically translated from English

Prior to 4D v17 R5, you may have discovered upon opening your 4D Write Pro document that the displayed font is not what it is supposed to be! If the document contains fonts which are not on your computer, 4D automatically replaced them with Times New Roman. However, since font preference is a matter of individual choice, this R-release gives you the ability to choose the replacement fonts!

4D Write Pro: More simple, more powerful

Automatically translated from English

A shout out to everyone using 4D Write Pro and letting us know your thoughts about the product. This lets us better understand your needs and difficulties. Thanks to this input, we’ve realized that some commands have become unnecessary, complex to use, and/or difficult to learn. Sometimes it could be the smallest things that make learning a challenge. For example, if you just want to insert some text in the footer, you first need to create an empty range! Why so complicated? Good question!

Thus, many commands that previously only used ranges have been extended in order to manage almost any kind of target (ranges, elements, sections, documents, etc.). Code is now easier to write and read. If you need to insert text … in a document, a footer, a range, (wherever!) …  just use it as the target and you’re off and running.

And that’s not all! Six commands have been renamed with shorter names, so they’re easier to remember.
