Bug 40400 – Refactoring: Simple shadow elements should be factored out .

• Component: Forms
• Status: RESOLVED FIXED

[Hajime Morrita]

There are several simple shadow element classes defined under rendering/*.cpp.
And some of them (ProgressValueElement, ShadowInputElement, SliderThumbElement) are 
pretty simple, and have similar definitions.
I'm going to another one for Bug 40280, so we should factored out the definition from them,
instead of making another copy.

This is a good refactoring.

Please check if we can share code with rendering/TextControllInnerElements.{cpp,h} too.


WebCore/WebCore.xcodeproj/project.pbxproj:21765
 +  				A7E5D1D111C0AE25000A338E /* ShadowElement.cpp in Sources */,
We should sort lists in project.pbxproj.
As you saw, the current pbxproj is not sorted correctly.  So you might want to run WebKitTools/Scripts/sort-Xcode-project-file before this change.

patch v2; sorted file order on project file

Hi Kent-san, thank you for reviewing!

> Please check if we can share code with rendering/TextControllInnerElements.{cpp,h} too.
Their lifecycle model is different a bit;
i.e. are created without parent node, then attached the Node after some operation.
Although it might be possible to adopt ShadowElement to them,
I would be better to keep as is for ShadowElement simplicity.

Sorted out with the script.

OK.
Please make sure all of layout tests pass on Mac before committing.
