I just went quickly over the patch. Sorry, no real review.

We have StringBuilder to build string effectively.

QColor -> const QColor&

Better give name for those magic numbers :)

What about removing the comment and adding an ASSERT? :)

> Source/WebCore/platform/qt/RenderThemeQtMobile.cpp:170
> +                  + (checked ? QLatin1String("-checked") : QLatin1String(""));

QLatin1String("") ? Not QLatin1String()?

true || ?

> Source/WebCore/platform/qt/RenderThemeQtMobile.cpp:184
> +// Assumption here is that we're working with a square size

ASSERT? :)

> +    const int border = size.width()/ 4;

Coding style: " / " :)

Uh?

> +    const int height = size.height() - 1;

Probably "side" instead of "height" or something like that?

We use FIXME.

our -> Our

PERIOD at the end of the sentence!!!!!
You are lucky Kenneth did not see the patch yet ;)

Not entirely true :-) It was way uglier in the Maemo 5 days, and it got a mini update for Grob.

What about using Nokia font if available?

space before {

So when does this happen that we dont have a context? Assert? Comment?

Just put that on one line

expandRectToSquare ?

is old stored somewhere? or could this be two lines? what about adding a comment and also I dislike old* :-) previous sounds more clear

& alighment

Also the name is not very clear, but I dont have any better suggestion. but I do like At better than For

Doesn't QLatin1String() work?

> Source/WebCore/platform/qt/RenderThemeQtMobile.cpp:226

why do you do with this width and not height which you use multiple places

> Source/WebCore/platform/qt/RenderThemeQtMobile.cpp:227
> +    const int middle = width / 2;

horizontalCenter? confusing with center below

> Source/WebCore/platform/qt/RenderThemeQtMobile.cpp:228
> +    const int vCenter = size.height() / 2;

v? vertical?

You seem to do this multiple places? maybe we need a dedicated method for doing this

comment? why - 1?

m_previousSmoothPixmapTransform ?

@Kenneth: that's a actually not a bad idea at all... ;)

Actually it shrinks, so I'd probably go with shrinkRectToSquare. Your comment makes it clear that the name is not clear enough :)

I basically named it that to be consistent with what was already there in stylePainter (oldBrush and oldAntiAliasing).

duh, I should really read things again sometimes. Remainders from testing something...

Interesting that this wasn't caught by check-webkit-style...

yup, I should definitely have proof-read that...

true. Should have done that when I changed the spacing to not be constant.

While I agree there seems to be a pattern, it's done in 4 places with a different number and type of arguments. I'm just not sure it's worth over-engineering...
