For code readability, I think "priv->pageProxy->XXX" needs to be placed to below priv->xxx setting list,

For example, like this.

#if USE(COORDINATED_GRAPHICS)
    priv->viewportHandler = EflViewportHandler::create(ewkView);
#endif

#if ENABLE(FULLSCREEN_API)
    priv->pageProxy->fullScreenManager()->setWebView(ewkView);
    priv->pageProxy->pageGroup()->preferences()->setFullScreenEnabled(true);
#endif

> Source/WebKit2/UIProcess/API/efl/ewk_view.cpp:1169
> +#if ENABLE(FULLSCREEN_API)

I think we don't need to use #if ENABLE in function inside for internal function.

> Source/WebKit2/UIProcess/API/efl/ewk_view.h:45
> + * - "fullscreen,enter", emitted when view is requested to enter full screen mode.

Missing *void* compared to other signal.

* - "load,provisional,redirect", void: view received redirect for provisional load.

> Tools/MiniBrowser/efl/main.c:25
>  #include <Evas.h>

Generally, we have used a new line before #ifdef in include file list.

Doesn't it allow to unskip any test?

> Source/WebKit2/UIProcess/API/efl/ewk_settings.cpp:34
> +Eina_Bool ewk_settings_fullscreen_enabled_set(Ewk_Settings *settings, Eina_Bool enable)

Star on wrong side.

> Source/WebKit2/UIProcess/API/efl/ewk_settings.cpp:36
> +    EINA_SAFETY_ON_NULL_RETURN_VAL(settings, false);

Can be moved inside the #if.

> Source/WebKit2/UIProcess/API/efl/ewk_settings.cpp:46
> +Eina_Bool ewk_settings_fullscreen_enabled_get(const Ewk_Settings *settings)

Star on wrong side.

> Source/WebKit2/UIProcess/API/efl/ewk_settings.cpp:48
> +    EINA_SAFETY_ON_NULL_RETURN_VAL(settings, false);

Ditto.

> Source/WebKit2/UIProcess/API/efl/ewk_view.cpp:1170
> +    evas_object_smart_callback_call(ewkView, "fullscreen,enter", 0);

What's the benefit / use case for sending signals to the client?
Why not call ecore_evas_fullscreen_set() directly on the view?

You should document what the default state is.

Ditto.

> Source/WebKit2/UIProcess/API/efl/tests/test_ewk2_settings.cpp:39
> +    ASSERT_TRUE(ewk_settings_fullscreen_enabled_set(settings, EINA_TRUE));

You should test the default state.

Move fullscreen_xxx to focus_out below for code readability.

Use static_cast<> instead of C type casting.

I think it's better to do not add '.' at the end of line for @param, @return doxygen tags. Those tags don't start the sentence (it's some kind of enumeration) so adding commas it's not recommended.

Grzegorz, thank you for your point out. I compared to local Tizen source. Sorry for noise.

Alexander, please fix except for '.'.

Looks make sense now.

Please use webkit style for flag naming.
