/**

 * @brief WebKit main smart object.

 *

 * This object is the high level access to WebKit-EFL browser

 * component. It is responsible for managing the main frame and other

 * critical resources.

 *

 * Every ewk_view has at least one frame, called "main frame" and

 * retrieved with ewk_view_frame_main_get(). Direct frame access is

 * often discouraged, it is recommended to use ewk_view functions

 * instead.

 *

 * The following signals (see evas_object_smart_callback_add()) are emitted:

 *

 *  - "ready", void: page is fully loaded.

 *  - "title,changed", const char*: title of the main frame changed.

 *  - "uri,changed", const char*: uri of the main frame changed.

 *  - "load,started", void: frame started loading.

 *  - "load,progress", double*: load progress changed (overall value

 *    from 0.0 to 1.0, connect to individual frames for fine grained).

 *  - "load,finished", const Ewk_Frame_Load_Error*: reports load

 *    finished and as argument @c NULL if successfully or pointer to

 *    structure defining the error.

 *  - "load,provisional", void: view started provisional load.

 *  - "load,error", const Ewk_Frame_Load_Error*: reports load failed

 *    and as argument a pointer to structure defining the error.

 *  - "frame,created", Evas_Object*: when frames are created, they are

 *    emitted in this signal.

 *  - "zoom,animated,end", void: requested animated zoom is finished.

 *  - "menubar,visible,set", Eina_Bool: set menubar visibility.

 *  - "menubar,visible,get", Eina_Bool *: expects a @c EINA_TRUE if menubar is

 *    visible; otherwise, @c EINA_FALSE.

 *  - "menubar,visible,set", Eina_Bool: set menubar visibility.

 *  - "menubar,visible,get", Eina_Bool *: expects a @c EINA_TRUE if menubar is

 *    visible; @c EINA_FALSE, otherwise.

 *  - "scrollbars,visible,set", Eina_Bool: set scrollbars visibility.

 *  - "scrollbars,visible,get", Eina_Bool *: expects a @c EINA_TRUE if scrollbars

 *    are visible; @c EINA_FALSE, otherwise.

 *  - "statusbar,visible,set", Eina_Bool: set statusbar visibility.

 *  - "statusbar,visible,get", Eina_Bool *: expects a @c EINA_TRUE if statusbar is

 *    visible; @c EINA_FALSE, otherwise.

 *  - "toolbar,visible,set", Eina_Bool: set toolbar visibility.

 *  - "toolbar,visible,get", Eina_Bool *: expects a @c EINA_TRUE if toolbar

 *    is visible; @c EINA_FALSE, otherwise.

 *  - "link,hover,in", const char *link[2]: reports mouse is over a link and as

 *    argument gives the url in link[0] and link's title in link[1].

 *  - "link,hover,out", const char *link[2]: reports mouse moved out from a link

 *    and as argument gives the url in link[0] and link's title in link[1].

 *  - "popup,create", Ewk_Menu: reports that a new menu was created.

 *  - "popup,willdeleted", Ewk_Menu: reports that a previously created menu is

 *    about to be deleted.

 *  - "download,request", Ewk_Download: reports a download is being requested

 *    and as arguments gives its details.

 *  - "icon,received", void: main frame received an icon.

 *  - "viewport,changed", void: Report that viewport has changed.
