Bug 188172 – [WinCairo] <select> elements do not popup options

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[Stephan Szabo]

On WinCairo (non-legacy) <select> elements do not pop up the list of options. Selecting the element multiple times in a row can cause assertion failures because the menu is not up.

Not "wincairo implementation" IIRC, but Windows implementation or AppleWin implementation.

Ditto.

WebKit prefers member initializer.

> +    int m_itemHeight;

I think WebKit prefers member initializer.
int m_clientPaddingLeft { 0 };
int m_clientPaddingRight { 0 };
int m_clientInsetLeft { 0 };
int m_clientInsetRight { 0 };
int m_popupWidth { 0 };
int m_itemHeight { 0 };

Is BString used?

Don't "using namespace std;"

You added this line. But, It seems for me that this line not needed. Does SystemParametersInfo change shouldAnimate if it fails?

> Source/WebKit/UIProcess/win/WebPopupMenuProxyWin.h:38
> +typedef struct HBITMAP__* HBITMAP;

<windows.h> is included in WebCorePrefix.h. I think you can remove these typedefs.

This was added in the similar place in the legacy path after the non-legacy code was removed.
