You want to visualize occurrences of a given variable in the 4D method editor? Or you find your method code too heavy with all those block icon and lines everywhere that it’s becoming hard to read?
With 4D v16 new preference options are available in the code editor to make the 4D developers’ life easier!!
If you’re used to run multiple 4D instances of an application on the same system, we are introducing with 4D v16 a feature that will simplify your life.
You now have the possibility to associate a set of different user settings with each data file.
Since 4D v11, the database server and SQL server both use preemptive multi-threading. Starting with 4D v13, the Web Server in Static mode also uses preemptive. Now with v15 R5, the 4D language can also be run in preemptive processes.
In 4D v16, a new Get 4D File command returns the file path to different 4D files. You can now easily retrieve the path for the following files:
- Backup configuration file
- Last backup file
- User structure settings file
- User data settings file
A picture field or variable can store different image formats – and even one image in several formats at the same time. As example, an image could be stored as PNG, SVG and MacPICT – in the same variable.
The new GET PICTURE FORMATS command permits you to get the number and types of format that are contained in a C_PICTURE variable.
4D v15 R5 introduces a new, simple and powerful way to exchange information between processes and also between processes and forms. This feature is based upon an asynchronous messaging system that allows processes and forms to be called and asked to execute methods with parameters in their own context.
Displaying a list where the line height would exactly fit the content is a very common need. 4D View Pro is including a new feature so that you can now control the height of each row independently in a listbox to make it fit to its content. To know more about 4D View Pro, check out this blog post.
There are actually now two ways to define the row height in a listbox:
- using new dedicated commands
- using a new control array
You want to insert your company logo in the signature of all your 4D Write Pro documents when they are being created? Or you want to add a product image for each of your invoices lines?
With 4D v16, it is now possible to insert inline pictures programmatically in your 4D Write Pro document with the dedicated command WP INSERT PICTURE!
In 4D v16 the texts for all the form objects (static texts, buttons, check boxes, etc…) will be stored in Unicode, allowing you to use characters from different languages directly in the form editor.
Especially for Asian or Eastern European languages this will ease the development process.
In 4D v16, you now have a new “On Mouse Up” event for non-draggable picture object!
This feature will provide you with an easy and notice way to draw and/or move SVG objects easily, removing the need for tricks as “SET TIMER(1)” to detect that the mouse button has been released.
