Octave-to-backend notification (2)

[Michael Goffioul]

Hi,

Could interested people review the experimental patch I pushed
on the graphics mq about octave to backend notification? The main
idea is to re-use and extend the generic system introduced by
Maciek and use integer ID's for property identification (to speed
up run-time execution).

There can be some variations possible. For instance, use a
per-object property notification method (figure_property_changed,
uicontrol_property_changed...). The same for object creation and
destruction. This can be easily implemented in octave code using
a double-dispatch mechanism between base_graphics_backend
and the object classes.

Comments are welcome

Thanks,
Michael.
