virtual void DD::Image::StringKnobI::default_value ( const char *  s, bool  store = false  )

pure virtual

Sets the default value for the StringKnob. If store is true then the string content is copied locally into the StringKnob, otherwise the calling object retains ownership of the string buffer.

virtual const char* DD::Image::StringKnobI::get_text ( const OutputContext *  context, bool  evaluate = true  ) const

pure virtual

evaluate only valid for EvalStringKnob subclasses. Returns a non-evaluated (raw) string if evaluate is false.
