If neither is your case, this text won't be of any use * for you. * * Elementary widgets are built in a @b hierarchical fashion. The idea * is to factorize as much code as possible between widgets with * behavioral similarities, as long as to facilitate the creation of * @b custom, new widgets, may the user need them. * * It all starts with a base class, which aggregates behaviour * @b every Elementary widget is supposed to have: * #Elm_Widget_Smart_Class. Every Elementary widget will be of that * type, be it directly or by means of @b inheriting from it. * * #Elm_Widget_Smart_Class happens to be an @c Evas_Smart_Class. If * you check out Evas' documentation on it, you'll see it's how one is * supposed to create custom Evas objects, what Elementary widgets * are. * * Once one instantiates an Elementary widget, since it inherits from * #Elm_Widget_Smart_Class, the system will raise a class instance of * that type for you. But that happens only @b once: the first time * you ask for an Elementary widget (of a given type). All subsequent * ones will only point to the very same class instance. Since it's * the class which points to the functions implementing the behavior * of objects of that type, all of the live instances of Elementary * widgets (of that type) will share the same blob of code loaded in * memory to execute their routines. * * Now go and take a look at #Elm_Widget_Smart_Class's fields. Because * it inherits from Evas' base smart class, we got a field of that * type as the first member, so that Evas can handle Elementary * objects internally as if they were 'normal' Evas objects. Evas has * the Evas-only behavior function pointers in there, so it's all it * needs. * * Then, comes a version field, so that whenever we got to update or * change the fields on our base smart class, there'll be a runtime * check of the version expected by Elementary and the one provided by * any code linking with it. A mismatch will show the developer of * that code he/she needs to recompile and link its code to a newer * version of Elementary. * * The next fields are the class functions itself. We call them * 'virtual' because, as in object-oriented languages, one is supposed * here to override them on inheriting classes. On most of * inheritances you'll probably want to call the parent's version of * the class function too: you must analise each case to tell. * * Take a look at #Elm_Widget_Smart_Data. That's private data bound to * each Elementary object @b instance. It aggregates data needed for * all widgets, since it's meant for the #Elm_Widget_Smart_Class-typed * ones. * * When inheriting from that base type, instance data for this new * class has to have, as the first member, a field of type * #Elm_Widget_Smart_Data. This has to be respected recursively -- if * a third class is to be created inheriting from the one that is a * direct 'child' of #Elm_Widget_Smart_Class, then the private data on * this third class has to have, as its first field, a variable of the * type of the private data of the second class (its parent), direct * child of #Elm_Widget_Smart_Class. * * [image here later, explaining process] * * It is from the base private data, #Elm_Widget_Smart_Data, that we * reach an object's class functions, by the given object * instance. This is the reason of the first field of that struct: a * pointer set to point to its class when the object is instantiated. * * @section elm-migration Elementary's Migration to a hierarchical schema * * What's been stated before is a work in progress. Elementary 1.0 is * @b not hierarchical in this way, but the idea is to get at this * shape, now. This section is here to explain the process of * migration, and it will be taken off once it's completed. * * We want to migrate widgets to the new schema progressively, one by * one. In order for this to happen without hurting anyone during the * process, it was made a @b compatibility class for Elementary * widgets, to take place of the old, unique smart class for * them. This is the role of #Elm_Widget_Compat_Smart_Class. * * All functions we had as 'hooks' before will be migrated to class * functions. As you can see, all calls to @b instance hooks on the * common code for widgets were replaced to class function calls * , now. It just happens that, for * #Elm_Widget_Compat_Smart_Class-typed widgets, i.e., the ones not * migrated to the new schema yet, class calls are proxyed back to * their instance 'hook' calls, that live on * #Elm_Widget_Compat_Smart_Data structs. Those structs are * #Elm_Widget_Smart_Data augmented with what is needed to reach the * original widget's data field set, so that things go on @b unnoticed * for the widgets awaiting translation to the new hierarchy. * * The following figure illustrates the old an new widget schemas, * with highlights on their differences. * * @image html elm-widget-hierarchy.png * @image rtf elm-widget-hierarchy.png * @image latex elm-widget-hierarchy.eps */ /** * @addtogroup Widget * @{ */ /** * @def ELM_WIDGET_CLASS * * Use this macro to cast whichever subclass of * #Elm_Widget_Smart_Class into it, so to acess its fields. * * @ingroup Widget */ #define ELM_WIDGET_CLASS(x) ((Elm_Widget_Smart_Class *) x) /** * @def ELM_WIDGET_DATA * * Use this macro to cast whichever subdata of * #Elm_Widget_Smart_Data into it, so to acess its fields. * * @ingroup Widget */ #define ELM_WIDGET_DATA(x) ((Elm_Widget_Smart_Data *) x) /** * @def ELM_WIDGET_SMART_CLASS_VERSION * * Current version for Elementary widget @b base smart class, a value * which goes to _Elm_Widget_Smart_Class::version. * * @ingroup Wiget */ #define ELM_WIDGET_SMART_CLASS_VERSION 1 /** * @def ELM_WIDGET_SMART_CLASS_INIT * * Initializer for a whole #Elm_Widget_Smart_Class structure, with * @c NULL values on its specific fields. * * @param smart_class_init initializer to use for the "base" field * (#Evas_Smart_Class). * * @see EVAS_SMART_CLASS_INIT_NULL * @see EVAS_SMART_CLASS_INIT_VERSION * @see EVAS_SMART_CLASS_INIT_NAME_VERSION * @see ELM_WIDGET_SMART_CLASS_INIT_NULL * @see ELM_WIDGET_SMART_CLASS_INIT_NAME_VERSION * * @ingroup Widget */ #define ELM_WIDGET_SMART_CLASS_INIT(smart_class_init) \ {smart_class_init, ELM_WIDGET_SMART_CLASS_VERSION, NULL, NULL, NULL, NULL, \ NULL, NULL, NULL, NULL, NULL} /** * @def ELM_WIDGET_SMART_CLASS_INIT_NULL * * Initializer to zero out a whole #Elm_Widget_Smart_Class structure. * * @see ELM_WIDGET_SMART_CLASS_INIT_NAME_VERSION * @see ELM_WIDGET_SMART_CLASS_INIT * * @ingroup Widget */ #define ELM_WIDGET_SMART_CLASS_INIT_NULL \ ELM_WIDGET_SMART_CLASS_INIT(EVAS_SMART_CLASS_INIT_NULL) /** * @def ELM_WIDGET_SMART_CLASS_INIT_NAME_VERSION * * Initializer to zero out a whole #Elm_Widget_Smart_Class structure and * set its name and version. * * This is similar to #ELM_WIDGET_SMART_CLASS_INIT_NULL, but it will * also set the version field of #Elm_Widget_Smart_Class (base field) * to the latest #ELM_WIDGET_SMART_CLASS_VERSION and name it to the * specific value. * * It will keep a reference to the name field as a "const char *", * i.e., the name must be available while the structure is * used (hint: static or global variable!) and must not be modified. * * @see ELM_WIDGET_SMART_CLASS_INIT_NULL * @see ELM_WIDGET_SMART_CLASS_INIT * * @ingroup Widget */ #define ELM_WIDGET_SMART_CLASS_INIT_NAME_VERSION(name) \ ELM_WIDGET_SMART_CLASS_INIT(EVAS_SMART_CLASS_INIT_NAME_VERSION(name)) /** * Base widget smart class.
