\subsection{Detailed Description}
Describes a callback issued by a smart object (\mbox{\hyperlink{group__Evas__Smart__Object__Group_gaa81bbe0af70df6c90b8fc781c59237bc}{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 {\ttfamily event\+\_\+info} will point to. \begin{Desc}

Hint on the type of {\ttfamily event\+\_\+info} parameter\textquotesingle{}s contents on a \mbox{\hyperlink{Evas__Common_8h_afbde245aa36db11d8280b266235c25b2}{Evas\+\_\+\+Smart\+\_\+\+Cb}} callback. 

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

\begin{DoxyItemize}
\item Structure with two integers\+: {\ttfamily \char`\"{}(ii)\char`\"{}} \end{DoxyItemize}
\begin{DoxyItemize}
\item Structure called \textquotesingle{}x\textquotesingle{} with two integers named \textquotesingle{}a\textquotesingle{} and \textquotesingle{}b\textquotesingle{}\+: {\ttfamily \char`\"{}\mbox{[}x\mbox{]}(\mbox{[}a\mbox{]}i\mbox{[}b\mbox{]}i)\char`\"{}} \end{DoxyItemize}
\begin{DoxyItemize}
\item Array of integers\+: {\ttfamily \char`\"{}ai\char`\"{}} \end{DoxyItemize}
\begin{DoxyItemize}
\item Array called \textquotesingle{}x\textquotesingle{} of struct with two integers\+: {\ttfamily \char`\"{}\mbox{[}x\mbox{]}a(ii)\char`\"{}} \end{DoxyItemize}
\begin{DoxyNote}{Note}
This type string is used as a hint and is {\bfseries 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.
