Correct.  The hidden attribute means the command line has no access to it.  I had asked the hidden attributed to be added, as I had inferred he was working on the c++ side.

He's working in C++, specifically modifying this to add a new parameter:

http://hg.savannah.gnu.org/hgweb/octave/file/0bf1d559b321/libinterp/interp-core/gl-render.cc#l2665

But it appears you can't get a property by name if it's hidden, even in C++. The other solution would be to use get_lineheight(), but that's not possible as you only have a base_properties object.

How will write access be prevented on the m-file side?

It shouldn't be prevented, otherwise the property is useless :)

Maybe I'm wrong, but I had the impression that a "hidden" property would not appear in the list of properties (e.g. in "get(h)"), but would still be readable/writable if you refer it by name.
