Data Structures |
struct | Etk_Type |
| The type of an Etk_Object: it can have a constructor and a destructor and can inherit from another Etk_Type
It also has a list of properties that will describe the state of the instanciated object. More...

Creates a new type. Will be automatically deleted with the etk_type_shutdown() call.
- Parameters:
-
| type_name | the name of the new type |
| parent_type | the type whom the new type inherits from (NULL if the new type is a root type) |
| type_size | the size of an instance |
| constructor | the constructor function |
| destructor | the destructor function |
| signals | array of Etk_Signal_Description that will be used to describe type signals at this level (parent signals will be inherited), this array should be terminated with ETK_SIGNAL_DESCRIPTION_SENTINEL. May be NULL if no signals should be defined. |
- Returns:
- Returns the new type on success, NULL on failure
