+ * Our example is remarkably simple, all it does is create an Ecore_Evas and
+ * register a callback for a bunch of events. What's interesting here is
+ * knowing when each of these callbacks will be called, however since that
+ * depends on the underlying windowing system there are no guarantees that all
+ * of the callbacks will be called for your windowing system. To know which
+ * callbacks will be called for your windowing system run the example and
+ * redirect the output to a file, and take a look at it.
+ *
+ * @note Make sure you minimize, resize, give and remove focus to see more
+ * callbacks called.
+ *
+ * Here you have the full-source of the code:
