This code places an Elementary diskselector widgets on a window, along with some buttons trigerring actions on it (though its API). It covers most of diskselector item functions.

On our {\ttfamily main} function, we are adding a default diskselector with 3 items. We are only setting their labels (second parameter of function elm\+\_\+diskselector\+\_\+item\+\_\+append)\+:

 Next we are adding lots of buttons, each one for a callback function that will realize a task covering part of diskselector items API. Lets check the first one\+:

\end{DoxyCodeInclude}
 We are labeling the button with a task description with elm\+\_\+object\+\_\+text\+\_\+set() and setting a callback function \doxylink{group__Evas__Smart__Object__Group_gac12dd6655f488cc47ce6cf00eb7d12b2}{evas\+\_\+object\+\_\+smart\+\_\+callback\+\_\+add()}. Each callback function will have the signature\+: {\ttfamily  static void \+\_\+task\+\_\+cb(void \texorpdfstring{$\ast$}{*}data, Evas\+\_\+\+Object \texorpdfstring{$\ast$}{*}obj, void \texorpdfstring{$\ast$}{*}event\+\_\+info)} with the function name varying for each task.

Now let\textquotesingle{}s cover all of them.

\end{DoxyCodeInclude}
 All items are included on diskselector after last one. You {\bfseries{can\textquotesingle{}t}} prepend items.

The first parameter of elm\+\_\+diskselector\+\_\+item\+\_\+append() is the diskselector object, that we are receiving as data on our callback function. The second one is a label, the string that will be placed in the center of our item. As we don\textquotesingle{}t want icons or callback functions, we can send NULL as third, fourth and fifth parameters.

\end{DoxyCodeInclude}
 If an icon is required, you can pass it as third parameter on our elm\+\_\+diskselector\+\_\+item\+\_\+append() function. It will be place on the left side of item\textquotesingle{}s label, that will be shifted to right a bit.

 To set a callback function that will be called every time an item is selected, i.\+e., everytime the diskselector stops with this item in center position, just pass the function as fourth parameter.

 If the callback function request an extra data, it can be attached to our item passing a pointer for data as fifth parameter. Our function \+\_\+sel\+\_\+data\+\_\+cb will receive it as {\ttfamily  void \texorpdfstring{$\ast$}{*}data }.

If you want to free this data, or handle that the way you need when the item is deleted, set a callback function for that, with \doxylink{group__Elm__General_ga2e17c3f1030712f3175f5b7812ada9a0}{elm\+\_\+object\+\_\+item\+\_\+del\+\_\+cb\+\_\+set()}.

As you can see we check if {\ttfamily it} is not {\ttfamily NULL} after appending it. If an error happens, we won\textquotesingle{}t try to set a function for it.

\end{DoxyCodeInclude}
 To delete an item we simple need to call \doxylink{group__Elm__General_gad1b5a0d41fa322b28000a290154ec3a4}{elm\+\_\+object\+\_\+item\+\_\+del()} with a pointer for such item.

If you need, you can get selected item with elm\+\_\+diskselector\+\_\+selected\+\_\+item\+\_\+get(), that will return a pointer for it.
