Hi Frank,

I guess exercise 34 is about adding decoration to a component (I don't
exactly know because I don't have the exercises ready). So what you
probably want to do is to decorate your editor with a form and with
buttons, exactly what WAFormDecoration is there for.

Add something like the following code to the #initialize method of
your component:

SomeComponent>>initialize
	super initialize.
	self addDecoration: (WAFormDecoration new
		buttons: #( ok cancel );
		yourself)

The setter #buttons defines the button-selectors that will be called
on your component, this means you should also implement
SomeComponent>>ok and SomeComponent>>cancel accordingly.

Hope this helps,
Lukas
