          | Gtk::StylePropertyBase::StylePropertyBase | ( | Gtk::Widget& | widget, |  
          |  |  | GType | value_type |  
          |  | ) |  |  |  | protected | 
 
Constructs a style property of type value_type for widget. 
The property is not registered in Gtk, call install_style_property() in order to do that. The properties are usually installed on the initialization of the first instance of a widget.
