Can not use the same drawing area routine? What is the limitation if it is
the same code?

I know the property, but there is no control that correctly represents what

Ohh.. Maybe understand this.. But in this case, limit the possibilities of

Oh.. No..
This component depends on the serial communication, and can not be added by
