I don't understand your question.
>>>case "radio": radio.setText(text); break;
duplicating much of Jarrett's comments:
>>In this case, it seems like keeping the controls in an AA would make a lot
>> Control[char] controls;
>> controls["speaker"] = new Slider();
>> controls["radio"] = new Button();
>> void setText(char name, char text)
> Dont see how this applies .
I think Jarrett is solving a more general problem that you are looking
at. Replace 'Control', 'Slider' and 'Button' with 'Text' and it might be
closer to what you want.

Unless you are willing to alter the source code for 'dwt.widgets.Text'
(and end up with a non-standard version) you can't add a function to
'dwt.widgets.Text'. The best you can do is derive a new class from it
and add your function to that.
Also, I don't think adding the function to Text will work anyway
because, If I understand you correctly, you want to call setText on
different instances of Text based on 'name'. For this to work the
setText(name,text) function needs to be attached to whatever holds the
reference to the Text instance.
Jumping back to the case you described befor this requiters that the new
function be attached to the Room class because it has the 'radio' and
void setText(char name, char text)
case "speaker": speaker.setText(text); break;
case "radio": radio.setText(text); break;
... // everything else
