Table pagination in 4D Write Pro

Automatically translated from English

Tables are a great feature in 4D Write Pro since they open a whole new world of possibilities. Their flexibility allows them to hold as many rows and columns as needed, and the cells can contain paragraphs and pictures.

Things just got even better with 4D v17 R2 thanks to a new feature: table pagination! And you don’t have to manage the pagination yourself, it’ll be fully automatic. No more counting rows to check a page’s size or orientation. From now on, the tables are dynamically split when a page or a column break occurs.

Display an entity selection in a list box

Automatically translated from English

4D v17 introduces a new concept: ORDA. If you’re not familiar with ORDA yet, we’ve created a series of blog posts to explain how to use and take advantage of ORDA. When working with ORDA, you’re going to use entity selections, which are basically objects containing references to entities belonging to the same dataclass (i.e. table). One of the main benefits of ORDA, is the very simple and powerful ability of binding with forms.

In this blog post, you’ll learn how to display an entity selection in a list box. In fact, it’s very simple.
