Bug 119120 – [EFL][WK2] Move and make WKColorPickerResultListener to EFL specific interface

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Ryuan Choi]

As 61276 and 119030 addressed, WK2 ports implement color picker as two way.
1. inherit WebColorPicker
2. register PageUIClient Callback

Only EFL port implements it as second way.
Second way might be good for some ports to expose UIClient as WK API.
But I think that it just make confusion.

I will refactor EFL port to use first way.

As far as I know, we have tried to use C API instead of inheriting WK2 internal class. This may violate a layer rule on EFL ewk implementation. Why not we use second way ?

We are using the C API on purpose. Using internal wk2 types from our API layer is a layering violation. Therefore, I believe this patch is a step in the wrong direction.

OK, but previous logic looks confusing because there were two paths in WebPageProxy and m_uiClient.showColorPicker was only for EFL (at least now)

Instead, I added Efl specific WK API to isolate color picker callbacks only for EFL.

r- because qt-wk2 ews is failed.

I'm not sure if we can use [EFL] prefix in title. Because this patch influences on QT and GTK ports. How about changing with "[WK2] Refactor color picker implementation for EFL port." ? It looks you need to get approval of WK2 owner.

introduces ?

I agree with you, so I wanted to separate patches about it because I think that this is for EFL.

If this approach is acceptable, I can move ColorPickerResultListener related files in another bug before landing this.
Or just removing "[EFL]" is acceptable, I will do it.

OK, I will fix it in next patch.

It is really not clear to me why this patch improves the current situation and the Changelog does not clarify things. It seems this patch mostly move generic WK2 code and makes it EFL-specific (thus preventing other ports from using it).

I don't understand this sentence.

I'm not sure we want to move this one to efl/. iirc, the file was put there in the first place because other ports showed interest in using  it as well.

Hi ryuan

Crash is happening while clicking to launch color picker.
It looks to me efl need your colorful this patch.

[Gyuyoung Kim]

Any update ?

Clearing flags. At least, this patch should be rebased.

I updated bug title and change log little bit.

Since I made this patch, EFL port has a crash when accessed color input.
I don't know who want to use WKColorPickerResultListener but I believe that EFL port will only use it until new port are appeared.

So, I want to move them out of the common code until someone raise their needs once more.

Are you sure if Mac or GTK won't use this logic in future ?

Why can't we initialize colorPickerClient when color picker needs to be shown ?

Add a new line.

Absolutely.
Mac implemented color picker using another way and GTK port does not use WK interface(And GTK also use color picker like Mac port, IIRC)
They don't need to use interface because they can implement picker in the platform.

But in EFL side, we can't implement complex UI components in ewebkit because we don't use elm.

It is to receive callback which notify when color picker needs to be shown.

OK, I will add it.

This patch was created a very long time ago. I think now is time to move this to EFL specific place. However, if any port will want to use this concept in future, we need to roll this change back. Looks fine for now.
