Define the font size for automatic font
In a previous R-release, we added two new automatic themes to define font and the font size, so there are three automatic themes at your disposal which respect the guidelines of each platform. To design your interface, the automatic theme is the recommended way to go with each form object using the font and size recommended by the OS.
In some cases, you may need more control and have valid reasons to ignore the guidelines. With 4D v18 R3, you can override the size of the automatic themes and have more control over how your text is displayed.
Objects Corner: easy sharing & other good news
How many times have you gotten the “Not supported value type in a shared object” error when trying to put an object into a shared object?
What did you do? Write longer code to turn your innocent object into a shared one, perhaps iterating over all of its properties?
How about transferring a shared object from one shared group to another?
An interesting thing about objects: you already know they can be used as a hash map (a key/value system), but what about gettings all the keys or all the values with a single line of code?
Keep reading, because 4D v18 R3 is out and brings good news!
4D for iOS Gallery: Ready-to-use templates
Very cool stuff is coming in 4D for iOS with 4D v18 R3! To make a long story short, 40+ ready-to-use templates are at your disposal and you have access to an additional integrated Gallery which can be used directly from the project editor. The gallery is based on a dynamic list of up-to-date templates from GitHub. Feel free to use and test the templates and even share your own custom-designed templates with other developers!
Enhanced XPath Support
XPath is a language allowing you to easily work with your XML documents. It’s already usable via the DOM Find XML element command and with 4D v18 R3, the support of the XPath syntax has been drastically enhanced. If you’re among those who requested features such as using a wildcard in a path, then keep reading!
4D Write Pro: New standard actions for tables, rows, and cells
ORDA – Better list box row selecting
Object-oriented programming in 4D: Manage class inheritance
In a previous blog post, we introduced a very important concept in object-oriented programming: Classes. Now we’ll go through another core concept: Inheritance, the mechanism that allows a class to acquire the behavior of another class.
ORDA: Breaking news for entity selection methods
When it comes to ORDA, 4D v18 R3 is full of good news! New member methods are at your disposal to further enhance your coding experience.
For starters, extracting data from an entity selection has been greatly enriched allowing you to build a fully customized collection with your entity selection data.
In addition, we’re providing you a way to indicate to an entity selection that its data needs to be refreshed from the server immediately, invalidating cached data.
Interested in some details? Keep reading, everything you need to know is below.
An intro to object-oriented programming in 4D: Classes
Many of you have have been asking to be able to define an object type ever since the Object type became available. Thanks to object notation, many of you dream of having object functions. Dream no more and say hello to classes in 4D v18 R3 project database! In this blog post, we’re introducing one of the most interesting concepts of object-oriented programming … along with a database example and a bonus video!
4D v18 R3 Beta starts today
We’re pleased to announce the launch of beta testing for 4D v18 R3! So what advances do this feature-release have to offer?
- We strive to evolve the 4D language for a seamless and intuitive coding experience. For this, the 4D language has taken a giant leap with the introduction of Classes.
- Never be at a loss when trying to determine which operation causes a server to be slow. A new command is at your disposal to help you detect operations exceeding a specified duration.
- ORDA also has its shares of features, for example, two new member methods. The first allows you to extract data from an entity selection, and the second enables you to immediately get refreshed data from the server.
- More than 40+ standard actions have been added to the 4D write Pro interface, extending development possibilities even further.
- As for 4D for iOS, 40+ ready-to-use templates are now at your disposal (accessible from the project editor.) A single click is all it takes to install the template of your choice.
- And much more (see below).
