Bug 90054 – [EFL][WK2] Make ewk_view inheritable in the WebKit2.

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Eunmi Lee]

The current ewk_view can not be inherited in the WebKit2 because the smart_class_set() API is not opened.
This bug will make ewk_view inheritable.

Why not use EWK_VIEW_SD_GET_OR_RETURN() instead of EWK_VIEW_SD_GET() ? Do you need to free ewkView object when failing to get smart data ?

Doesn't we need to expose this?

Yes, I think it is better to free the ewkView and return 0 when we fail to create SmartData and Private Data because the ewkView does not work correctly without them.

I think we don't have to expose now because we can not create Ewk_Page_Group yet.
We can expose that when API to create Ewk_Page_Group is added.

Shouldn't we use EINA_SAFETY_ON_NULL_RETURN_VAL(ewkPageGroup, 0); ? Passing NULL is not valid API use IMHO.

Can't we make this function name a bit shorter? :)

Yes, right. It's better to use EINA_SAFETY in this case. I will change it.

Yes, the name is long. so how about ewk_view_add_with_WKType()?

What does that mean (sorry didnt look at the patch yet)? You will be able to reuse all the API? Are you sure that is a good idea? bringing over legacy?

I want to make ewk_view inheritable like WebKit1's ewk_view,
because I want to make ewk_view_touchscreen which inherits the ewk_view.
You can see the Bug 88631.
Actually I can make ewk_view_touchscreen without inheritance, but I think I have to do duplicated works such as drawing contents without inheritance.

If you think my answer is not enough, please feel free to ask me again :)

Look at where the industry is going. Every browser will support touch screens and might even do so as well as supporting mouse (think windows 8). I think you should forget about current desktop use cases (legacy) and concentrate on creating a top-notch mobile web view, because the mobile is moving to the desktop and not the other way around.

Kenneth, thank you for your comments.

Yes, right. the mobile is getting important these days,
and I also considered how to support touch screens as well as supporting mouse.
but, in my conclusion, I can not support both touch screen and mouse at the same time now in the EFL port.
Because, Evas can not discriminate the touchscreen's input and mouse's input.
That means, Evas generates "Mouse Event" when we touch the touchscreen and it also generates "Mouse Event" for Mouse device's operation.
I want to do scrolling for "Mouse down, move, up" on the touchscreen, but I want to do dragging for that with the mouse device,
so, I can not support touch screen and mouse at the same time.

Additionally, I think I can write the code to support touchscreen using "if else" statement in the all mouse event callback to separate the touchscreen and mouse in the ewk_view.cpp.
But, IMO, it is better to inherit and override the mouse event instead of using "if else" statement.

I really want to listen your thought about that. :)

BTW, This patch is for making ewk_view inheritable.
the ewk_view_touchscreen is just a one example of inheritance,
and I think it will be useful for applications to extend ewk_view functions if ewk_view is inheritable.
So, would you review this patch for that?
The discussion for ewk_view_touchscreen, will be applied in the Bug 88631.

Qt has had the same issues but it is almost fixed now ;-) EFL developers should look at how we are fixing this. What you can do while this is not working is adding a method like "ewk_enable_mouse_events() / ewk_enable_touch_events()" to ignore one or the other.

Then you will have a problem in the future when your view supports both. Think about the future :-)

It can also easily become a can or worms (talking from experience). What is it that you need from the view that can only be solved by inheritance? why are free functions not good enough?

Thanks for your advice.I hope EFL becomes good like Qt and I have to study Qt port. :)
and, I will modify Bug 88631 to use API such as ewk_enable_touch_events() to distinguish touch and mouse event.

Yes, right. If I add ewk_view_touchscreen, I have to merge codes of ewk_view_touchscreen to the ewk_view when view supports both mouse and touch.
I didn't consider about that. and I think it is better to use "if else" statement in this case. :)

There is 8 Smart Class functions in the ewk_view such as mouse_down, key_down, focus_in and so on, and the ewk_view offers the default behavior of them.
I think application can want to do different operations for those Smart Class functions.
If we do not allow the inheritance, the application (or extending library) can not override Smart Class functions.
I don't want to restrict applications' possibility. so I want to make the ewk_view inheritable.

> Patch

I've uploaded new patch for inheritance.

I made patch to add the initialize API to the SmartClass before, but I've changed my mind, because I think it is not clear to call initialize API in the object which inherits the ewk_view.

In the new patch, I make ewk_view inheritable by exposing the ewk_view_smart_class_set() and getting Ewk_View_Smart_Class_Data as a second parameter.

In order to make the ewk_view inheritable, I have to create PageClientImpl in the not ewk_view_base_add() but _smart_add().
but there is a problem because the _smart_add() can not pass the data to create PageClientImpl.
(Unlike WK1 EFL, we have to pass the data which is used to create WebPage in the WK2 such as Context and PageGroup.)
so, I have to consider how to pass the data to the ewk_view's constructor, and I've decided to use Smart_Class's data.

The Smart_Class's data was used only for type before, but I've made Ewk_View_Smart_Class_Data to store Context and PageGroup as well as type.

It's difficult for me to find what you change.
Although I know why you did, we'd better not to touch others if possible.

If I am right, Smart class is shared for all ewkView object so that we will have only one ewk_context.

I've changed the data of smart class, so I think it is reasonable to modify above codes.

The smart class is not shared for all ewkView object,
and each ewkView has its own smart class.
so, would you explain your thought again? I can not catch your point.

Although you call ewk_view_smart_class_new with different data, api and smart will be initialized only one time.

Now, I've finally got what you mean.
You mean I don't have to move "\" in the 96~113 line.
If it is OK to break the style, I will modify patch to not move the "\".

I didn't catch the Ewk_View_Smart_Class is "static".
I will remove "static" to set the data for each ewk_view.

I've try to remove static and allocate memory for Ewk_View_Smart_Class,
but I can't find the way to free the allocated Smart_Class! :(
because returned smart class from evas_smart_class_get() is "const" type.

I have to find another way for making ewk_view inheritable with specific data.

patch to make ewk_view inheritable

I've got an advice from EFL community to make Evas_Object inheritable with specific value.
http://sourceforge.net/mailarchive/forum.php?thread_name=CAOtL8OpdAnDSRWv2Vdn1F%2B1b_Hm7vhKVs%3DwHLcB1rSDO3KvdEw%40mail.gmail.com&forum_name=enlightenment-devel

I've made patch by referencing elementary's elm_widget.
The elm_widget provides elm_widget_add() which accepts parent as a parameter,
and the widget which inherits elm_widget creates its Evas_Object using elm_widget_add() instead of evas_object_smart_add().

In this patch, the ewk_view provides ewk_view_smart_add() API to create Evas_Object for WebKit2 EFL,
so, the object which inherits ewk_view can use that API to create Evas_Object and the ewk_view can get Ewk_Context using the ewk_view_smart_add()'s parameter.

I hope this patch can be the final patch for inheritance :)

Thank you.

Looks better than before, I have only below nit from this patch.

And I want to know whether this has any regression to run WTR/Efl.
Previously, WTR/Efl did not use Ewk_Context.

Sorry, please ignore this, I missed that second argument of _ewk_view_initialize is different.

Looks good to me if we don't have regression for WTR/Efl.

Please check WTR/Efl with/without this patch.

from_WKContext?

I think this with_WKType is confusing. What is a WKType? Plus you have multiple arguments...  why not just like ewk_view_add_internal or so

the old name seems better

Thanks for your comment :)
I've checked with WTR/Efl and there is no regression with this patch.

Yes, I understand the ewk_view_add_with_WKType is confusing.
I think it is better to use old name.
