[EFL] Functions needing Ewk_View_Private_Data as parameter are not part of public API.

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Ryuan Choi]

WebKit/EFL have many APIs, but some of them looks not useless.

First, functions including Ewk_View_Private_Data should be private or change it to Evas_Object.

ewk_view_repaints_get(Ewk_View_Private_Data*, ...)
ewk_view_scroll_requests_get(Ewk_View_Private_Data*, ...)
ewk_view_repaint_add(Ewk_View_Private_Data*, ...)
ewk_view_layout_if_needed_recursive(Ewk_View_Private_Data*, ...)
ewk_view_scrolls_process(Ewk_View_Private_Data*, ...)

I checked old eve(I'll check latest in my home) and our browser, but those are only used internally.
Does it required?

My first suggestion is moving them to ewk_private.h
If not, how do you think about change it to Evas_Object?

[KwangHyuk]

Good Idea,

As ewk_private has some WebCore dependency, I prefer creation of ewk_view_private.h.
I don't want both two (single and tiled view) to be tightly coupled with WebCore.

It's needed if user wants to subclass the backing store. It's explained in comments above their declarations in Source/WebKit/efl/ewk/ewk_view.h

So, there's not much we can do here.

No, every private functions goes to ewk_private.h, but as explained above we can not move these functions.

Changing the header doesn't change anything about this.

Thinking again... I think not all of them are used by a subclass implementation and the others we could indeed change to use Evas_Object as argument.

Hi, Lucas.
Long time no see.


If ewk_view_tiled and ewk_view_single would include ewk_private.h, It would include unnecessary header file, I don't like it.

I talked privately to Antognolli about this. We agreed that all these functions can be moved to ewk_private.h


> If not, how do you think about change it to Evas_Object?

If at any time they are needed outside of WebKit, we can move them back, but using the Evas_Object.

May be, ewk_view_single.c and ewk_view_tiled.c would need ewk_private.h.

It's not related to the patch, but it's ok to go in.

I tested when I upload and it's fine for me.
And although those files required ewk_private.h,
those can't include ewk_private.h because ewk_private.h include c++ matter.

So, we need to find proper way if it required.
I think that we can make other bugs to control it when it required.

BTW, Can I know why those files use *.c ?
If we don't have any reasons, it looks be better to change *.cpp.
it's just my two cents.

Thanks, english is more difficult than code fore me. :)
I'll update like you mentioned.

[KwangHyuk]

In fact, there are three more apis which are using private data as parameter of theirs.

EAPI Ewk_View_Paint_Context *ewk_view_paint_context_new(Ewk_View_Private_Data *priv, cairo_t *cr);
EAPI Eina_Bool ewk_view_paint(Ewk_View_Private_Data *priv, cairo_t *cr, const Eina_Rectangle *area);
EAPI Eina_Bool ewk_view_paint_contents(Ewk_View_Private_Data *priv, cairo_t *cr, const Eina_Rectangle *area);

I hope that you can consider them too.

Right, I want refactoring them also.
But now they can't go into ewk_private.h and I need to check whether it should be moved or not.
I'll investigate them.
