I know that a lot of the code in this file is shared by the <select> popup (except on Mac) and by the Autofill popup.  I believe we only want these changes to affect the Autofill popup.  Have you verified that this is indeed the case?

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:79
> +static const int kLineHeightMargin = 3; // Line height margin put at the top and bottom of each line.

nit: This should probably be called "kLineHeightPadding" -- margins would be allowed to overlap, whereas this is additive, like padding.

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:208
> +    // Paint an top and bottom padding.

nit: "an" -> "the"

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:858
> +void PopupListBox::paintTopBottomPadding(GraphicsContext* gc, const IntRect& rect)

nit: Perhaps "paintVerticalPadding"?

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:864
> +    Color backColor = m_popupClient->itemStyle(0).backgroundColor();

nit: Prefer to use unabbreviated names -- in this case, "backgroundColor"

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:868
> +    topRect.move(0, - kPaddingHeight);

nit: Omit the space in "- kPaddingHeight" since this is a unary minus

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:957
> +        gc->fillRect(separatorRect, Color(0xcd, 0xcd, 0xcd), ColorSpaceDeviceRGB);

nit: I wonder if there's an existing named color for this.  It seems a little weird to declare a color constant as a function parameter.  I'm not completely up to speed on WebKit style guidelines, though.

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:1146
> +        return separatorHeight;

nit: As mentioned in the Chromium bug, we might want a few pixels of padding around the separator.  I'd need to see more screenshots or play with the code to have a beter idea of what exactly we want here, though.

I verified them, but I assumed the other popups also need to obey this rule. I'll leave the other popups as it is.

My plan is
1, Add whole padding and margin information into PopupMenuStyle.
2, Add popup window type into PopupMenuStyle and according to the type, change the margin.

I prefer to 1.

There is not #cdcdcd color in Webkit as defined. But as I suggested in bug track comment, I will use #c0c0c0 which is Color::lightGray. That would be better.

As Roma isn't worried about it, so I will leave here.

Once I got ToT, my webkit-patch upload doesn't work anymore because of exception. Now I'm investigating...

So I upload it manually.

Long-term, we want to more cleanly separate the Autofill popup code from the <select> popup code -- the current dual-purpose code can be a bit clumsy to update.  I agree that (1) is probably a better short term solution that (2) though -- perhaps some WebKit folks more familiar with this code could comment?

Ok :)

Nearly all of these are fairly opinionated nits -- feel free to ignore ones that seem totally bogus to you.  One the whole, this looks pretty good to me, but I am not a WebKit reviewer.

> Source/WebCore/ChangeLog:12
> +        Put PopupMenuStyle::paddingLineHeightk() at the top and bottom of each line.

nit: Stray 'k's in the function names

> Source/WebCore/platform/PopupMenuStyle.h:38
> +    PopupMenuStyle(const Color& foreground, const Color& background, const Font& font, bool visible, bool isDisplayNone, Length textIndent, TextDirection textDirection, bool hasTextDirectionOverride, int paddingHeight, int paddingLineHeight)

nit: "listBoxPaddingHeight" and "linePaddingHeight" might be slightly clearer names for these variables.

> Source/WebCore/platform/PopupMenuStyle.h:72
> +    int m_paddingHeight; // Padding height put at the top and bottom of window.

nit: "window" -> "popup"

> Source/WebCore/platform/PopupMenuStyle.h:73
> +    int m_paddingLineHeight; // Padding line height put at the top and bottom of each line.

nit: "Padding line height" -> "Padding height" (you already mention that this is for each line later in the comment)

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:954
> +        gc->fillRect(separatorRect, Color::lightGray, ColorSpaceDeviceRGB);

Is it possible for a <select> popup to have a separator?  If so, again, I think we only want this change for the Autofill popup.  (I'm not 100% sure about that though.)

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:1352
> +    int windowHeight = menuStyle.paddingHeight(); // Top padding heights is added first.

nit: remove "heights"

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:1366
> +    windowHeight += menuStyle.paddingHeight(); // Bottom padding heights is added last.

nit: remove "heights"

Ilya,

Hmm... I'm also not sure we will have separator for other popup windows. At least, we don't have any separator tag for select html tag though. We also can drag the padding value with PopupMenuStyle. But the class is getting bigger...

[Naoki Takano]

So is there anybody who can review my patch?

Especially it is very helpful to let me know if the separator padding width should be configurable or not with PopupMenuStyle.

[Naoki Takano]

After looking around the source code, I notice itemIsSeparator() might return true even if not AutoFillPopupMenuClient. So it implies other popup window separator might be drawn.

Ok, I add one more parameter to PopupMenuStyle and drag it.

<select> can have an <hr> child, and the <hr> is rendered as a separator though the HTML parser doesn't support this structure.  (HTML5 parser regression??)

Please avoid new bool parameter.  We prefer introducing enum. Also, we can avoid updating RenderMenuList and RenderTextConstrolSingleLine by a default parameter.

enum PopupMenuType { SelectPopup, AutofillPopup };
PopupMenuStyle(const Color&...., PopupMenuType menuType = SelectPopup)

Do not use "k" prefix for constant values.

Add spaces around "*"

I assumed any default parameter is prohibited.
I believe it it true in Chromium project, but is WetKit different?

I referred to
 static const int kLabelToIconPadding = 5;
 static const int kMinEndOfLinePadding = 2;

They start with "k", but do I have change "kLinePaddingHeight" to "linePaddingHeight"?

Yes. WebKit is not Chromium. You can see a lot of default parameter usages in WebKit.

It's ok to keep "k" if you think consistency in this file is more important than consistency in WebKit.
Anyway, I expect someone makes a patch to remove all of "k" prefixes in PopupMenuChromium.cpp and ScrollbarThemeChromiumWin.cpp later.

Looks ok.

Roma requests very tiny parameter tuning, maybe 0.8 to 0.9.

Sorry for bothering you again.

But I just changed 0.8 to 0.9 ratio for label font.
