Hi,

GLMRubScrolledTextBrick is a wrapper around��RubScrollTextMorph.

I see that it is a common practice in Pharo to implement decorator / wrapper pattern using��doesNotUnderstand:.

Reference:

�� -��AthensWrappedWorldDisplay

�� -��DictionaryValueHolder

�� -��MorphicTreeAdapter

�� -��RubEditingArea

�� -��RubParagraphDecorator

�� -��RTShapeBuilder

�� -��RTShowLabel

Is there a better way to implement a decorator or a wrapper around the object with many api methods rather then��doesNotUnderstand:?

Cheers,

Alex

cannot find the method.
This is because it is implemented in RubScrollTextMorph.
GLMRubScrolledTextBrick implements #doesNotUnderstand: to send it to the
rubric object.
