If you’re interested in the user interface, you may have already used the On before keystroke and On after keystroke events. You’ll certainly be happy to know that the handling of these events has been greatly enhanced with 4D v18 R5. In addition, a new command has been created to determine if there is ongoing input when the On before keystroke event is generated. Let’s find out more!
4D v18 R5 provides a new 4D command to open a form in the form editor. This can be especially useful for analysis or introspection tools.
Using $1, $2, and $n variables in your code not only makes the code less readable, it can also increase confusion since the human brain can find it difficult to remember what these variables correspond to. The solution is to create a variable with an understandable name and assign it the value of $1, $2, or $n.
4D v18 R5 has good news, you can now name your parameters when declaring:
- a project method,
- a trigger
- a database method
- a form method
- a constructor of a class
- a function of a class.
Let’s see how!
