List of all members.

Detailed Description

Serves as a common interface to all properties.

Namely, it provides an top-level interface for signals and RTTI information. Since Property is a template class that inherits from Object, this serves as a common ancestor.

It is useful for generic containers of properties, such as that used by Introspectable.

Constructor & Destructor Documentation

Idioskopos::Object::Object ( const Glib::ustring &  name,
Introspectable container,
sigc::slot< void >  slot = sigc::slot< void >() 
)

Constructor that adds this property to the introspectable container and will identify this property by the given name.

Glib::ustring Idioskopos::Object::value (  )  [virtual]

Virtual method implemented by children to return a string representation of the contained value.

Reimplemented in Idioskopos::ReadOnlyPropertyBase< T >, Idioskopos::ReadOnlyPropertyBase< std::vector< X, A > >, Idioskopos::ReadOnlyPropertyBase< IdioskoposArray< X, N > >, Idioskopos::ReadOnlyPropertyBase< double >, Idioskopos::ReadOnlyPropertyBase< std::string >, Idioskopos::ReadOnlyPropertyBase< std::vector< bool, A > >, Idioskopos::ReadOnlyPropertyBase< int >, Idioskopos::ReadOnlyPropertyBase< VerySimple >, Idioskopos::ReadOnlyPropertyBase< std::vector< double > >, and Idioskopos::ReadOnlyPropertyBase< IdioskoposArray< int, 10 > >.

size_t Idioskopos::Object::num_properties (  )  const [virtual]

If this is a property container, this should be reimplemented to provide a true count of the number of child properties this container has.

Reimplemented in Idioskopos::Introspectable, Idioskopos::PropertyBase< std::vector< X, A > >, and Idioskopos::PropertyBase< IdioskoposArray< X, N > >.

Object & Idioskopos::Object::operator[] ( const Glib::ustring &  name  )  throw (error::bad_property_name) [virtual]

This method returns an Object reference and throws exceptions when a bad name is encountered.

The alternative would be to return an Object* and return NULL for an unfound name. However, by returning a reference, it is possible to index into objects using array notation, as in myobject["child"]["property"]

Reimplemented in Idioskopos::Introspectable.
