Returns:

An iterator of all the registered EXTERNAL types.

Each item in the iterator is an Eina_Hash_Tuple which has the type of the external in the key and #Edje_External_Type as data.

 const Eina_Hash_Tuple *tuple;
 Eina_Iterator *itr;
 const Eina_List *l, *modules;
 const char *s;

 modules = edje_available_modules_get();
 EINA_LIST_FOREACH(modules, l, s)
   {
      if (!edje_module_load(s))
        printf("Error loading edje module: %s\n", s);
   }

 itr = edje_external_iterator_get();
 EINA_ITERATOR_FOREACH(itr, tuple)
   {
      const char *name = tuple->key;
      const Edje_External_Type *type = tuple->data;

      if ((!type) ||
          (type->abi_version != edje_external_type_abi_version_get()))
        {
           printf("Error: invalid type %p (abi: %d, expected: %d)\n",
                   type, type ? type->abi_version : 0,
                   edje_external_type_abi_version_get());
           continue;
        }

      printf("%s: %s (%s) label='%s' desc='%s'\n",
             name, type->module, type->module_name,
             type->label_get ? type->label_get(type->data) : "",
             type->description_get ? type->description_get(type->data) : "");
   }

Since :

3.0

Gets the value of the given parameter of boolean type.

Look for the key parameter in the params list and return its value in ret. If the parameter is found and is of type EDJE_EXTERNAL_PARAM_TYPE_BOOL, its value will be stored in the Eina_Bool pointed by ret, returning EINA_TRUE. In any other case, the function returns EINA_FALSE.

Parameters:

params	List of parameters where to look
key	Name of the parameter to fetch
ret	Eina_Bool pointer where to store the value, must not be NULL.

Returns:

EINA_TRUE if the parameter was found and is of boolean type, EINA_FALSE otherwise.

Since :

3.0

Gets the value of the given parameter of choice type.

Look for the key parameter in the params list and return its value in ret. If the parameter is found and is of type EDJE_EXTERNAL_PARAM_TYPE_CHOICE, its value will be stored in the string pointed by ret, returning EINA_TRUE. In any other case, the function returns EINA_FALSE.

The string stored in ret must not be freed or modified.

Parameters:

params	List of parameters where to look
key	Name of the parameter to fetch
ret	String pointer where to store the value, must not be NULL.

Returns:

EINA_TRUE if the parameter was found and is of integer type, EINA_FALSE otherwise.

Since :

3.0

Gets the value of the given parameter of double type.

Look for the key parameter in the params list and return its value in ret. If the parameter is found and is of type EDJE_EXTERNAL_PARAM_TYPE_DOUBLE, its value will be stored in the double pointed by ret, returning EINA_TRUE. In any other case, the function returns EINA_FALSE.

Parameters:

params	List of parameters where to look
key	Name of the parameter to fetch
ret	Double pointer where to store the value, must not be NULL.

Returns:

EINA_TRUE if the parameter was found and is of double type, EINA_FALSE otherwise.

Since :

3.0

Convenience function to find a specific parameter in a list of them.

Parameters:

params	The list of parameters for the external
key	The parameter to look for

Returns:

The matching Edje_External_Param or NULL if it's not found.

Since :

3.0

Gets the array of parameters information about a type given its name.

Note:

the type names and other strings are static, that means they are NOT translated. One must use Edje_External_Type::translate() to translate those.

Parameters:

type_name

Edje external type name

Returns:

the NULL terminated array, or NULL if type is unknown or it does not have any parameter information.

edje_external_type_get()

Since :

3.0

Gets the value of the given parameter of integer type.

Look for the key parameter in the params list and return its value in ret. If the parameter is found and is of type EDJE_EXTERNAL_PARAM_TYPE_INT, its value will be stored in the int pointed by ret, returning EINA_TRUE. In any other case, the function returns EINA_FALSE.

Parameters:

params	List of parameters where to look
key	Name of the parameter to fetch
ret	Int pointer where to store the value, must not be NULL.

Returns:

EINA_TRUE if the parameter was found and is of integer type, EINA_FALSE otherwise.

Since :

3.0

Gets the value of the given parameter of string type.

Look for the key parameter in the params list and return its value in ret. If the parameter is found and is of type EDJE_EXTERNAL_PARAM_TYPE_STRING, its value will be stored in the pointer pointed by ret, returning EINA_TRUE. In any other case, the function returns EINA_FALSE.

The string stored in ret must not be freed or modified.

Parameters:

params	List of parameters where to look
key	Name of the parameter to fetch
ret	String pointer where to store the value, must not be NULL.

Returns:

EINA_TRUE if the parameter was found and is of string type, EINA_FALSE otherwise.

Since :

3.0

Returns the current ABI version for Edje_External_Type structure.

Always check this number before accessing Edje_External_Type in your own software. If the number is not the same, your software may access invalid memory and crash, or just get garbage values.

Warning:

NEVER, EVER define your own Edje_External_Type using the return of this function as it will change as Edje library (libedje.so) changes, but your type definition will not. Instead, use #EDJE_EXTERNAL_TYPE_ABI_VERSION.

Summary:

• use edje_external_type_abi_version_get() to check.
• use #EDJE_EXTERNAL_TYPE_ABI_VERSION to define/declare.

Returns:

The external ABI version the Edje library was compiled with. That is, the value #EDJE_EXTERNAL_TYPE_ABI_VERSION had at that moment.

Since :

3.0

Registers a batch of types and their information.

When several types will be registered it is recommended to use this function instead of several calls to edje_external_type_register(), as it is faster.

Note:

The contents of the array will be referenced directly for as long as the type remains registered, so both the name and info in the array must be kept alive during all this period (usually, the entire program lifetime). The most common case would be to keep the array as a static const type anyway.

Parameters:

array

NULL terminated array with type name and information. Note that type name or information are referenced directly, so they must be kept alive after this function returns!

Returns:

EINA_TRUE on success, EINA_FALSE on failure (like type already registered).

See also:

edje_external_type_register()

Since :

3.0

Unregisters a batch of given external type previously registered.

Parameters:

array

NULL terminated array, should be the same as the one used to register with edje_external_type_array_register()

See also:

edje_external_type_unregister()

Since :

3.0

Gets the #Edje_External_Type that defines an EXTERNAL type registered with the name type_name.

Since :

3.0

Registers a type to be used by EXTERNAL parts.

Parts of type EXTERNAL will call user defined functions to create and manipulate the object that's allocated in that part. This is done by expecifying in the source property of the part the name of the external to use, which must be one registered with this function.

Parameters:

type_name	Name to register and be known by edje's "source:" parameter of "type: EXTERNAL" parts.
type_info	Meta-information describing how to interact with it.

Returns:

EINA_TRUE on success, EINA_FALSE on failure (like type already registered).

See also:

edje_external_type_array_register()

Since :

3.0

Unregisters a previously registered EXTERNAL type.

Parameters:

type_name

name to unregister. It should have been registered with edje_external_type_register() before.

Returns:

EINA_TRUE on success, EINA_FALSE on failure (like type_name did not exist).
