Detailed Description

Functions that deal with messages.

Edje has two communication interfaces between code and theme. Signals and messages.

Edje messages are one of the communication interfaces between code and a given Edje object's theme. With messages, one can communicate values like strings, float numbers and integer numbers. Moreover, messages can be identified by integer numbers. See Edje_Message_Type for the full list of message types.

Note

Messages must be handled by scripts.

Typedef Documentation

typedef enum _Edje_Message_Type Edje_Message_Type

Identifiers of Edje message types, which can be sent back and forth code and a given Edje object's theme file/group.

edje_object_message_send()

edje_object_message_handler_set()

typedef void(* Edje_Message_Handler_Cb) (void *data, Evas_Object *obj, Edje_Message_Type type, int id, void *msg)

Edje message handler callback functions's prototype definition.

data will have the auxiliary data pointer set at the time the callback registration. obj will be a pointer the Edje object where the message comes from. type will identify the type of the given message and msg will be a pointer the message's contents, de facto, which depend on type.

Enumerator
EDJE_MESSAGE_STRING	A message with a string as value. Use #Edje_Message_String structs as message body, for this type.
EDJE_MESSAGE_INT	A message with an integer number as value. Use #Edje_Message_Int structs as message body, for this type.
EDJE_MESSAGE_FLOAT	A message with a floating pointer number as value. Use #Edje_Message_Float structs as message body, for this type.
EDJE_MESSAGE_STRING_SET	A message with a list of strings as value. Use #Edje_Message_String_Set structs as message body, for this type.
EDJE_MESSAGE_INT_SET	A message with a list of integer numbers as value. Use #Edje_Message_Int_Set structs as message body, for this type.
EDJE_MESSAGE_FLOAT_SET	A message with a list of floating point numbers as value. Use #Edje_Message_Float_Set structs as message body, for this type.
EDJE_MESSAGE_STRING_INT	A message with a struct containing a string and an integer number as value. Use #Edje_Message_String_Int structs as message body, for this type.
EDJE_MESSAGE_STRING_FLOAT	A message with a struct containing a string and a floating point number as value. Use #Edje_Message_String_Float structs as message body, for this type.
EDJE_MESSAGE_STRING_INT_SET	A message with a struct containing a string and list of integer numbers as value. Use #Edje_Message_String_Int_Set structs as message body, for this type.
EDJE_MESSAGE_STRING_FLOAT_SET	A message with a struct containing a string and list of floating point numbers as value. Use #Edje_Message_String_Float_Set structs as message body, for this type.

Function Documentation

void edje_message_signal_process

(

void

)

Process all queued up edje messages.

This function triggers the processing of messages addressed to any (alive) edje objects.
