Re: Help with Clutter::Scriptable

[Brian Gregg <biscuitalmighty gmail com>]

Am I right to assume that the constructor call to Glib::ObjectBase("TypeName") needs to be called to create the type before I load the object from script?  I would need to instantiate a TypeName object before the script would understand the type exists correct?

You can define a custom GType when deriving in C++. You must call the
virtual base constructor (weirdness ahoy) in your initializer list:
http://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/custom/custom_widget/mywidget.cc#n26

Then you can presumably just mention that GType name in your JSON
script.

If it helps, you can add regular GObject properties by just using
Glib:property_proxy<> as a member variable.
