These are not useful for widgets of asciiStringWidgetClass.

If I understand you correctly:  
Don't re-assign the address of the string.  Think of the address of the
string as specifying a buffer.  To reset the string displayed by the
buffer, set the first character in the buffer to the null character.
The asciiStringWidget uses the buffer in-place; if you loose the address
of the buffer, you loose control over what it contains.
