Detailed Description

Describes a callback issued by a smart object (evas_object_smart_callback_call()), as defined in its smart object class.

This is particularly useful to explain to end users and their code (i.e., introspection) what the parameter event_info will point to.

Examples

evas-smart-interface.c, and evas-smart-object.c.

Field Documentation

type

const char* _Evas_Smart_Cb_Description::type

Hint on the type of event_info parameter's contents on a Evas_Smart_Cb callback.

The type string uses the pattern similar to http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-signatures, but extended to optionally include variable names within brackets preceding types. Example:

• Structure with two integers: "(ii)"

• Structure called 'x' with two integers named 'a' and 'b': "[x]([a]i[b]i)"

• Array of integers: "ai"

• Array called 'x' of struct with two integers: "[x]a(ii)"

Note

This type string is used as a hint and is not validated or enforced in any way. Implementors should make the best use of it to help bindings, documentation and other users of introspection features.
