ORDA – Genealogy – Episode three
In the first and second episodes of this trilogy, we demonstrated the basics of ORDA using list boxes, entities, and entity selections. We also showed the way to use similar list boxes with distinct data sources and how to use Meta info expression to improve the list boxes’ graphics.
Today we’re going to have even more fun, with less code!
ORDA – Genealogy – Episode two
In the first episode of this trilogy, we demonstrated the basics of ORDA using list boxes, entities, and entity selections. Today, we’re going a bit deeper by running some queries that will take advantage of recursive relationships. We’ll also have a quick look at how to display list boxes nicely using the “meta info expression” property.
ORDA – Genealogy – Episode one
We can all agree that ORDA is a great 4D V17 feature. A kind of revolution in the way of thinking and programming. 4D databases will never be seen the same way as before.
ORDA allows you to conceive advanced applications in less time, with more readable and clean code. To show you the power of ORDA we’ve prepared a series of tips for you, divided into three episodes. In this first episode, we’ll demonstrate how links should now be considered more as entities and entity collections, and we’ll show you how listboxes can now be based on entity selections, rather than selections or arrays.
4D Write Pro: A new bar is born!
We couldn’t be more thrilled to announce the birth of a new element in the 4D Write Pro Family: a new toolbar for 4D Write Pro!
Thanks to a design on point, the user experience is even better for creating documents.
Flash news about 4D Write Pro and anchored images
Flash news: 4D Write Pro anchored images now support 4D Expressions!
Since 4D v16 R6, it’s been possible to add anchored images to 4D Write Pro documents. Once inserted, these images were static, either defined with a picture variable (or field), or by a picture path. Today, you have more flexibility: a valid 4D expression can also be associated to an anchored picture!
Table pagination in 4D Write Pro
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.
Times inside objects… (and everywhere else)
Objects are at it again, continuing to demonstrate their utility to ease your life as a developer.
Using time (or duration) values inside of objects is now smoother and more intuitive. Beginning with 4D v17, times inside objects are set as seconds – and not milliseconds!
How to easily handle text insertion in 4D Write Pro
4D Write Pro packs in a lot of commands and functions allowing you to create and handle complex documents by programming, documents which include pictures and text! Today, 4D Write Pro gets its own commands to insert and read text without needing to use commands originally designed for Styled Text! Thanks to these new commands, your code takes full advantage of the 4D Write Pro programming concepts, i.e. objects and ranges. Thus, your code is more elegant and easier to read!
Get the position of any part of a 4D Write Pro document
4D Write Pro is continuously evolving; thanks to the new features and functionalities we’re shipping with every R-release. A world of possibilities is wide open! Today, thanks to a new command, you can get a set of information about the location of any element within your documents.
Use table ranges in 4D Write Pro
Since 4D v16 R4, it’s been possible to create tables by programming in your 4D Write Pro documents. Styling the whole table or just certain cells could be done during the creation of the document, but maybe you also want to manage your tables afterwards. Now, it’s easy to manipulate tables in an existing document, to change the border style or color, to change the font size or make it bold, etc.
4D Write Pro programming is highly based on “ranges“. After paragraph ranges and picture ranges, 4D v17 introduces a new type of range: table ranges, returned by a new command: WP Create table range. Styling tables is now simple with this new command and new type of range!
