I want to add a methd to an instance of dwt.widgets.Text.

void setText(char[] name, char[] text){  name.setText(text);}

there is  ' setText(char[] text)  ' in the base class

each instance has a name. I cannot get this to work? 
the Tango book covers this very weakly

I'm not following what you want to do. Do you want to add methods to a class that inherits from dwt.widgets.Text? Do you want to add a method to a particular object at run time? (BTW this is not possible) Do you want to add method to a the dwt.widgets.Text class?

class MyClass : dwt.widgets.Text { void setText(char[] name, char[] text){ name.setText(text);} } does that work for what you want?

Yes

It is also this -I am using numerous text boxes each with a name . and I want to change the text on each as I create it I need a method to make the normal 'setText(text) method into setText( name,text)
