Create function binding
In addition to variable bindings, a function binding can be created. A function binding can be created for all control properties, if the JavaScript functions return a suitable value for the property of the control. A function binding can be used for conversions, for example.
A function binding is created with the Create function binding command.
An active function binding is identified by fx highlighted in blue.
The parameter values of the function are transferred directly in the Properties window.
In addition, it is possible to implement custom JavaScript functions and create a function binding for them. Further information can be found here.
