Please review.

This is a pretty corner case, but definitely it is a bug.

In chromimu, I filed the bug at
http://code.google.com/p/chromium/issues/detail?id=83539

Thanks,

This looks reasonable, but I'm not sure I'm the right person to review this patch.

[Naoki Takano]

Thanks, Adam.

I hope tkent@ or iserman@ will review.

nit: This line can be moved out of the if/else, since it is the same in both places.

nit: I think these three lines would be clearer as
windowWidth = m_maxWindowWidth;
baseWidth = windowWidth - scrollbarWidth - paddingWidth;

If you don't find that clearer, though, feel free to leave this as is.

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:1386

nit: Is this line not redundant with the else of the if/else below?

Ilya,

Thank you for your review.

I don't think so, because only this is not "if/else" but "if/else if", and only if width is change, we want to call setMaxWidthAndLayout().

Ah, you're right -- my bad.

I am not a WebKit reviewer, but this looks good to me.

> Source/WebCore/ChangeLog:11
> +        * manual-tests/autofill-popup-location.html: With long ong text, test the shown location is correct.

nit: Please remove "ong"

> Source/WebCore/platform/chromium/PopupMenuChromium.cpp:364
> +        // When clipping, we have to set and notify listBox() the change.

nit: This comment might be clearer as """When clipping, we also need to set a maximum width for the list box."""

Does it mean type the text and then type ENTER to submit the form?

ditto.

> Source/WebCore/manual-tests/autofill-popup-location.html:29
> +    <form><input name=p autofocus></form>

This HTML already has an input with autofocus.  Multiple autofocus inputs are confusing.

> +        , m_maxWindowWidth(INT_MAX)

Because this is a C++ code, we had better use numeric_limits<int>::max() instead of INT_MAX.

ok

> +        , m_maxWindowWidth(std::numeric_limits<int>::max())

nit: We usually declare "using namespace std;" at the beginning of the file, and omit 'std::' in the code.

[Naoki Takano]

Thanks, Kent-san.

Once I fix select event bug, I will clean up code about this namespace std problem and const static k* values problem.
