Does the JS macros run as a instance of widget?

[Danielo Rodríguez]

Reviewing the code of the qualify macro I realized it uses the following method

this.getStateQualifier();

This is a method of the widget class. Does this mean that JS macros are executed as widgets? Or they just get a reference to their parent widget on their this?

Yes, JavaScript macros are invoked with `this` pointing to the widget in whose context the macro is executing.

Hello Jeremy,

Thank you for the confirmation. That is very convenient!
Does that mean that we can create javascript macros that decorates their parent widget? Or is it a bad idea?

It’s a very, very bad idea. Macros are intended to be idempotent, because they have no control over when they are executed.

Best wishes

Jeremy.
