\subsection{Detailed Description}
Interface between pages of the \hyperlink{group__Prefs_elm-prefs-widget}{Prefs} widget and the real widgets implementing them. 

This structure defines the interface between the \hyperlink{group__Prefs_elm-prefs-widget}{Prefs} widget's pages and Elementary widgets implementing them.

It is {\bfseries mandatory} that the following functions be implemented, at least, for a page widget\-:


\begin{DoxyItemize}
\item \hyperlink{struct__Elm__Prefs__Page__Iface_a1a665de3ea5a485d8131dce40158b544}{Elm\-\_\-\-Prefs\-\_\-\-Page\-\_\-\-Iface\-::add}
\item \hyperlink{struct__Elm__Prefs__Page__Iface_a7e866f775f44c6b86f8eac1be321dab5}{Elm\-\_\-\-Prefs\-\_\-\-Page\-\_\-\-Iface\-::item\-\_\-pack}
\item \hyperlink{struct__Elm__Prefs__Page__Iface_a93b8c7d37f88f9623e9189bc89f8d514}{Elm\-\_\-\-Prefs\-\_\-\-Page\-\_\-\-Iface\-::item\-\_\-unpack}

\item \#\-Elm\-\_\-\-Prefs\-\_\-\-Page\-\_\-\-Iface\-::item\-\_\-pack\-\_\-after
\end{DoxyItemize}

\begin{DoxyNote}{Note}

Function to instantiate the page widget. 

It must return the widget handle, which should be the {\ttfamily obj} argument on the functions which follow. That object argument, by the way, should always have their respective \#\-Elm\-\_\-\-Prefs\-\_\-\-Page\-\_\-\-Node handle accessible via a {\ttfamily \char`\"{}prefs\-\_\-page\char`\"{}} Evas object data value. The return value of the following functions should be {\ttfamily E\-I\-N\-A\-\_\-\-T\-R\-U\-E}, on success or {\ttfamily E\-I\-N\-A\-\_\-\-F\-A\-L\-S\-E}, otherwise.
