Hi,

The following patch does two things:

- Removed unnecessary variable whose associated code was removed recently.
  This is an internal variable and hence is safe from BIC.

- Fix the problem of the line widget not being properly updated when 
  ::setReadOnly is called.  To see the effect, compile the unit test and 
  toggle and untoggle the Read Only button.

Regards,
Dawit A.
