Bug 107820 – [EFL][WK2] Use C API inside ewk_settings

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Chris Dumez]

As per Bug 107657, we should start using the C API internally to avoid violating layering.

Nice and there existed C API already for all of them!

Almost all of them. We will have to decide what to do about the others later.

LGTM overall.

would prefer having method definition here (it's just 1 line), that would make it inline automatically.

Putting inline on a member function that is not defined in its header file (or a header file) is weird. Please either remove the inline or make the function actually be inline.

I don't get this. You get the PageGroup as an argument of the constructor, yet you extract (an other?) PageGroup from m_webView?
Why not construct the attribute from your parameters?

Why not make preferences() const instead of const-cast every access?

You can remove the inline keyword, it is redundant. Make this const?

Because the pagegroup passed to the constructor may be NULL. Retrieving it from the WebPage / WebPageProxy makes sure that it is constructed / valid.

Having null opaque objects is something I almost only see in the EFL port.

How does that happen?

This is called directly from:
WKViewRef WKViewCreate(Evas* canvas, WKContextRef contextRef, WKPageGroupRef pageGroupRef)

In that C API, pageGroupRef may be NULL if we wish the view to create its own new page group.

Take Benjamin's comment into consideration. I opened Bug 109276 to address the issue about the WKPageGroupRef being NULL. For now, this patch still retrieves the page group from the page to make sure it is not NULL. This can be improved if Bug 109276 lands.

LGTM, but let's fix the dependencies first in your other patch before we go ahead.
Then you can fix this line and land.

It seems to me Chris isn't interested in this issue nowadays.

LGTM, however, Benjamin might have a concern about this.

In r159896, WebPageGroup is never null, so it seems to be okay but needs confirm from Benjamin.
