Bug 63857 – [DRT] implement createPopupMenu for Chromium DRT port

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Johnny(Jianning) Ding]

In WebKit, the keystroke configurations of selection list below (see dom/SelectElement.cpp)

// Configure platform-specific behavior when focused pop-up receives arrow/space/return keystroke.
// (PLATFORM(MAC) and PLATFORM(GTK) are always false in Chromium, hence the extra tests.)
#if PLATFORM(MAC) || (PLATFORM(CHROMIUM) && OS(DARWIN))
#define ARROW_KEYS_POP_MENU 1
#define SPACE_OR_RETURN_POP_MENU 0
#elif PLATFORM(GTK) || (PLATFORM(CHROMIUM) && OS(UNIX))
#define ARROW_KEYS_POP_MENU 0
#define SPACE_OR_RETURN_POP_MENU 1
#else
#define ARROW_KEYS_POP_MENU 0
#define SPACE_OR_RETURN_POP_MENU 0
#endif

According to the configuration, On Linux and Chromium unix-like platforms, with configuration of SPACE_OR_RETURN_POP_MENU, pressing '\r' or space on a <select> which acts as menuList render object is to trigger showing popup menu. (instead of doing implicit submit, see SelectElement::menuListDefaultEventHandler.). However the behavior causes crash on Chromium's layout tests. It's because showing popup calls WebViewHost::createPopupMenu() which is not implemented by Chromium DRT. Like test LayoutTest/fast/forms/select-script-onchange.html. See bug 61515.

I am working on a patch to fix this issue, which simply creating WebPopupMenu with a empty WidgetClient delegate. It should be enough for layout test.

Looks good to me, but someone else has to approve as I'm not a reviewer.
Please fix all reported style issues as well.

Just some small style nits.

> +        if (widget)

Nit: Do we really need this check?  Shouldn't WebPopupMenu::create always succeed?

> Tools/DumpRenderTree/chromium/WebViewHost.cpp:254
> +    default:
> +        ASSERT_NOT_REACHED();

I would remove the default case.  That way if someone adds another WebPopupType, there will be a compiler error and the person can update this code.

> Tools/DumpRenderTree/chromium/WebViewHost.cpp:261
> +    // In Chromium, we do not this method.

Nit: This comment isn't that useful.  Can you either explain why we don't need this method or just remove the comment?

If not considering OOM situation, we need not to check the pointer. I will drop it since WebKit will eventually crash if OOM.
