Can we just use RenderThemeEfl ?

Get the RenderThemeEfl from the scrollbar, Drawing the scrollbar using the RenderThemeEfl. If you agree, I will proceed to implement the scrollbar.

I think that it's better than before. Although I am not sure whether it is right to access FrameView and Page here, I think that we don't have another choice until we refactor RenderTheme. > Source/WebCore/platform/efl/ScrollbarThemeEfl.h:40 > +class ScrollbarThemeEfl : public ScrollbarThemeComposite { why do you remove final? > Source/WebCore/platform/efl/ScrollbarThemeEfl.h:42 > + virtual ~ScrollbarThemeEfl(); If this is final, we can remove virtual. and how about `~ScrollbarThemeEfl() = default` ? > Source/WebCore/platform/efl/ScrollbarThemeEfl.h:44 > + virtual int scrollbarThickness(ScrollbarControlSize = RegularScrollbar) override; I am not sure, didn't webkit decide skip `virtual` keyword since `override` keyword was introduced.

It looks you just copy win port implementation. If so, win port can use *c* prefix because it means *CoreUI*.

What is difference between this new *paintThemePart* and > existing one ? Existing *paintThemePart* need the renderObject to apply the Edje State. But *ScrollbarThemeEfl* didn't pass the RenderObject to draw the scrollbar. So I create the new function to draw the scrollbar. > > > Source/WebCore/platform/efl/ScrollbarThemeEfl.cpp:46 > > +static const int cScrollbarThickness = 10; > > What does "c" prefix mean ?

Oh,, *paintThemePart* have to be placed in public scope to access this function in ScrollbarThemeEfl.
