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

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

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

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\+UE}, on success or {\ttfamily E\+I\+N\+A\+\_\+\+F\+A\+L\+SE}, otherwise.
