[Octave-bug-tracker] [bug #35329] change of paperorientation does not update papersize

[Ben Abbott]

Follow-up Comment #4, bug #35329 (project octave):

Opps, I submitted before I was done.

In 2008, I looked at implementing all the listeners as m-files. The problem I
encountered was how to go about registering the listeners as objects were
created.

In addition, the listeners tend to recursive. For example, changing papertype
triggers a change to papersize, changing papersize triggers a change to
papertype, & orientation. So it is necessary to suppress recursion while the
listener is updating.

Since there is a partial c++ side implementation for the paper properties, it
is either necessary to extend the c++ code, or to remove it and rely upon
m-files entirely. 

In either event, I still have my work from 2008. I'll dig it out and see if I
can separate the part for the paper properties.
