Check if you need to initialize m_rect that way, it may default to 0,0,0,0 anyway.

Better do early return style:

return true;

Please make sure to only include the ones you need, for example JSC includes can go to the .cpp.

Yong can review this better than me. I do wonder if popUp is a good name.

Combine the two lines above into one line.

I think early return is preferred here:

if (!m_page) {
    m_page->clear();
    return;
}
m_page->

It is an interesting way to do it. I'm always worried about JS re-entrancy. So please make sure it cannot be triggered by JS code.

Also, where are the other parts? I cannot finish reviewing without seeing how PagePopupBlackBerry is used. Can I assume it is already working well?

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:43
> +#define urlbarHeight 70

1. all letters should in capital case for macros.
2. I would use enum/const in a namespace/class scope.

Also why 70? Where is the number determined? Should we query it from webpageclient dynamically?

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:62
> +    WebPagePrivate* webPage()
> +    {

this method can be const

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:73
> +PagePopupBlackBerry::PagePopupBlackBerry(BlackBerry::WebKit::WebPagePrivate* webPage,
> +        PagePopupClient* client, const IntRect& rect) :
> +        m_webPagePrivate(webPage), m_client(client)

Is the style right? I would write it like this:

PagePopupBlackBerry::PagePopupBlackBerry(BlackBerry::WebKit::WebPagePrivate* webPage, PagePopupClient* client, const IntRect& rect)
   : m_webPagePrivate(webPage)
   , m_client(client)

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:76
> +    m_rect = IntRect(rect.x(), rect.y() - urlbarHeight,
> +            client->contentSize().width(), client->contentSize().height());

one line should be enough.

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:89
> +bool PagePopupBlackBerry::init(WebPage* webpage)
> +{

I would use initialize

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:91
> +    if (!webpage)
> +        return false;

is it necessary?

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:144
> +    char* strArgs = new char[sizeUTF8];

I would use WTF::Vector<char>

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:244
> +    delete m_client;
> +    m_client = 0;

I think the client should delete itself in didClosePopup. Or we can use a OwnPtr, and get PassOwnPtr<PopupClient> passed in through contructor.

Other than the "strArgs" issue, the patch looks good to me

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:143
> +    WTF::Vector<char> strArgs;
> +    JSStringGetUTF8CString(string, strArgs.data(), sizeUTF8);

We have to allocate enough buffer for strArgs. Otherwise strArgs.data() is a null pointer. The reason I suggested to use Vector<char> is I hate "delete". OwnArrayPtr<char> should also work.

> Source/WebKit/blackberry/WebCoreSupport/PagePopupBlackBerry.cpp:152
> +    client->setValueAndClosePopup(0, strArgs.data());

Are we sure the string data has a null terminator included? Otherwise, we have to pass the string length.

I'd rather keep this method, because it might get call to change the rect in the runtime.
