* The embed widget allows you to add Etk widgets in your Evas programs,
without having to create an Etk_Window. @n
- * The embed widget is created with etk_embed_new() which requires a valid
Evas and, optionally, a function to call
- * to get the position of the window containing the Evas. This function is
used to know where the popup-windows should
- * be popped up. Thus, this is not required if the embed widget doesn't make
any window pop up (i.e. if it contains no
- * menu-bar, no combobox, ...). @n
+ * The embed widget is created with etk_embed_new() which only requires the
Evas where to create the embed object. You
+ * can then get the corresponding Evas object with etk_embed_object_get().
This object can be manipulated as any other
+ * Evas objects, with evas_object_move(), evas_object_resize(),
evas_object_show(), ... @n
+ *
+ * If the embed widget contains widgets that makes popup-windows pop up (such
as a combobox or a menubar), you should
+ * also call etk_embed_position_method_set() to set the function to call to
get the position of the Evas where the embed
+ * object belongs. Without this function, the menus and the combobox-windows
will pop up at an incorrect position. @n
+ * Also, if the embed widget contains widgets that may change the mouse
pointer (such as an entry or a tree), you have
+ * to call etk_embed_pointer_method_set() to set the function to call to
change the current mouse pointer. Otherwise,
+ * the mouse pointer will not be changed. @n
