General question about inheritance of properties in GTK

["Clarity ThroughConfusion" <claritythroughconfusion hotmail co uk>]

Hi,

I am planning on creating some custom widgets that have some additional 
functionality over standard GTK widgets.
As these widgets are very close to the GTK standard widgets, I am planning 
on deriving the custom widget from a GTK standard widget and hopefully avoid 
reimplementing the common functionality.

However, I am having problems understanding the inheritance of properties, 
could anyone help me understand the following:

1. How can I reuse the parent widgets properties along with my new 
properties I have created using g_object_class_install_property?

2. Are the parents properties inherited and set by default in the child?

3. Do I need to have case statements for each parent property (in addition 
to my new ones) in set_property() function?

I have looked through the developer.gnome.org ebooks and done a google, but 
can not find any helpful info.

Regards

Clarity
