can we call Class Events from Control or Form

[Vaibhav khopade]

Hi,

Is there a way to call Custom Class Events from a Control on Form or from script of a Form ?

Yes, the method you are looking for is on the ScriptedController (ScreenController/FormController) in the UI. It is usually accessed as ‘this’ in a screen or form. It comes in two forms, one for instance methods and one for static methods:

(this’invokeMethod classSym method parameters filters commit)

Java

+ScreenController.invokeMethod(classSym method parameters filters commit): any Invokes static method on a class. Arguments classSym symbol Class symbol. method symbol Method symbol to invoke. parameters list List of name, value pairs of parameters. filters list List of active nodes to send filters for. commit boolean Commit flag.

Arguments classSym symbol Class symbol. method symbol Method symbol to invoke. parameters list List of name, value pairs of parameters. filters list List of active nodes to send filters for. commit boolean Commit flag.

(this’invokeMethod instance method filters commit)

Java

As with all of our scripting help, this information is available in NexJ Studio by hovering over the method name in code. Also, just by pressing the ‘ character after ‘this’ in a screen or form will give you a list of all of the available methods and their documentation.
