When generating .4dz files, 4D uses a standard zip format by default. If you are a software publisher, you’ll be happy to know that 4D v19 R2 added a feature that allows preventing users of your application from seeing the content of the 4DZ, and therefore from being able to modify it.
4D v19 R2 comes with a new version of SpreadJS and a Ribbon update that is compatible with it. Let’s discover the new features offered by this new version.
When printing, page break location is set by default, but you can adjust the print area by defining your own page breaks.
Starting with 4D v19 R2, to help your customers choose where they want to place their page breaks, 4D View Pro lets you add and remove page breaks manually, and also display the print preview lines.
Several predefined actions that help your app users manage their content were already available in the Action section: “Add,” “Edit,” “Delete,” and “Share”. 4D v19 R2 introduces a new one, and you’re going to like it! You can now create Sort actions to sort local app data.
In the latest versions of 4D, several improvements have been made to simplify the writing of code with classes:
- function and attribute suggestions according to type
- display of the prototype with a short description
With 4D v19 R2, you can open the online documentation of a function with a single action.
For some time, you’ve been able to create your own custom data formatters and convert strings, booleans, or integers to images in your generated app.
This new 4D v19 R2 feature will allow you to take full advantage of those formatters for iOS and Android, and make sure images look good in both light and dark appearances.
Let’s see how!
Sometimes, you need to display different tables of information in one document. For better visibility, it’s often necessary to display them in different sheets. In this case, you need to create, rename, hide or remove a sheet, or simply know which sheet the user is currently on.
With 4D v19 R2, you can manage the sheets in your 4D View Pro documents by programming.
With the introduction of classes in the 4D environment, the need to store your data in objects, and especially blobs, has increased. That’s why 4D v19 R2 lets you encapsulate blobs in objects.
Beyond the storage aspect, since the blob object is a reference type, your performance in terms of memory occupation and speed will be greatly improved.
Best practices in IT sometimes change, and the management of certain invisible characters in text files is one example. End of Line (EOL) characters have evolved, especially for version control systems integration purposes. In the same way, the Byte Order Mark (BOM) on Unicode text files is less and less used.
With 4D v19 R2, 4D has evolved smoothly to follow these best practices, giving you more flexibility along the way.
That also includes a crucial step: choosing a main color for the app. That’s why, since the introduction of 4D for iOS, the main color of your mobile application was defined by the dominant color of your application’s logo.
With 4D v19 R2, we’re giving you a feature that lets you easily define the main color of your iOS and Android app, by selecting it from a color picker fully integrated into the project editor.
