NameProperty -- The base class of all Config4GNU properties. DescriptionThe Property type is the base type for all properties in Config4GNU.
A property is an association between a name and a value. Properties
also have descriptions, data types, and default values. Properties are
attached to a Node. To create a property, use node_add_property(). The Property must be
created using a Node because the type of Property created will depend
on what type of Node it is for. The Property class described on this
page is an abstract type. It defines methods and properties, but no
implementation. For an implementation of Property that uses XML for
storage, see XMLProperty. DetailsPROPERTY()#define PROPERTY(obj) (G_TYPE_CHECK_INSTANCE_CAST ((obj), property_get_type(), Property)) |

Registers the Property type if necessary. property_get_name ()gchar* property_get_name (Property *me); |
Accesses the name of a property. The Property class by itself
does not implement this method. The XMLProperty class returns the
value of the name attribute on the property element. property_get_value ()gchar* property_get_value (Property *me); |
Accesses the value of a property. The Property class by itself does
not implement this method. The XMLProperty class returns the
content of the child element <value> that exists in the <property>
element. property_set_value ()void property_set_value (Property *me,
const char *value); |
Changes the value of a property. The XMLProperty class implements
this method by changing the content of the <value> element that
exists in the <property> element. property_get_default ()gchar* property_get_default (Property *me); |
Accesses the default value of a property. This information is used
when a property value is needed but no value is defined. This
information is also used to display in a user front-end. property_get_description ()gchar* property_get_description (Property *me); |
Accesses the description for a property. The description is defined
in the class definition file. The information is used to display in
a user front-end, as the user is editing a property's value. | |
