Information about an external type to be used.
This structure provides information on how to display and modify a third party Evas_Object in Edje.
Some function pointers are not really used by Edje, but provide means for Edje users to better interact with such objects. For instance, an editor may use label_get() and icon_get() to list all registered external types.
| unsigned int _Edje_External_Type::abi_version |
always use:
Referenced by edje_external_type_array_register(), and edje_external_type_register().
| const char* _Edje_External_Type::module |
Name of the module that holds these definitions, as used in the externals {} block of a theme definition.
| const char* _Edje_External_Type::module_name |
Canonical name of the module, for displaying in edition programs, for example.
| Evas_Object*(* _Edje_External_Type::add) (void *data, Evas *evas, Evas_Object *parent, const Eina_List *params, const char *part_name) |
Creates the object to be used by Edje as the part.
part_name is the name of the part that holds the object and can be used to forward callbacks from the object as signals from Edje. params is the list of Edje_External_Param, not parsed, from the default state of the part. Parameters of type EDJE_EXTERNAL_PARAM_FLAGS_CONSTRUCTOR should be set on the object here.
| void(* _Edje_External_Type::state_set) (void *data, Evas_Object *obj, const void *from_params, const void *to_params, float pos) |
Called upon state changes, including the initial "default" 0.0 state.
Parameters are the value returned by params_parse(). The pos parameter is a value between 0.0 and 1.0 indicating the position in time within the state transition.
| Eina_Bool(* _Edje_External_Type::param_set) (void *data, Evas_Object *obj, const Edje_External_Param *param) |
Dynamically change a parameter of this external, called by scripts and user code.
Returns EINA_TRUE on success
| Eina_Bool(* _Edje_External_Type::param_get) (void *data, const Evas_Object *obj, Edje_External_Param *param) |
Dynamically fetch a parameter of this external, called by scripts and user code.
Returns EINA_TRUE on success. (Must check parameter name and type!)
| Evas_Object*(* _Edje_External_Type::content_get) (void *data, const Evas_Object *obj, const char *content) |
Dynamically fetch a sub object of this external, called by scripts and user code.
Returns Evas_Object * on success. (Must check parameter name and type!)
| void*(* _Edje_External_Type::params_parse) (void *data, Evas_Object *obj, const Eina_List *params) |
Parses the list of parameters, converting into a friendly representation.
Used with state_set()
| const char*(* _Edje_External_Type::label_get) (void *data) |
Get a label to use to identify this EXTERNAL.
(For editors)
| const char*(* _Edje_External_Type::description_get) (void *data) |
Get a user friendly description of this EXTERNAL.
(For editors)
| Evas_Object*(* _Edje_External_Type::icon_add) (void *data, Evas *e) |
Get an icon to use to identify this EXTERNAL.
(For editors)
| Evas_Object*(* _Edje_External_Type::preview_add) (void *data, Evas *e) |
Get a preview of the EXTERNAL object in use.
(For editors)
| Edje_External_Param_Info* _Edje_External_Type::parameters_info |
An array of Edje_External_Param_Info describing the different parameters this EXTERNAL may have.
The last element in the array must be #EDJE_EXTERNAL_PARAM_INFO_SENTINEL.
| void* _Edje_External_Type::data |
Private user data that will be passed to all of the class functions.
