We are trying to keep toolkit/desktop, core operating system, and
graphics API dependencies separate. We haven't fully deployed this in
WebCore, but you can see what the #ifdefs would look like from
We'll use PLATFORM(DARWIN), PLATFORM(WIN_OS) and PLATFORM(POSIX) for
actual OS ependencies.
We'll use PLATFORM(MAC), PLATFORM(WIN) and (presumably) PLATFORM
(KDE), PLATFORM(GTK), PLATFORM(WXWIDGETS), PLATFORM(S60), etc for the
toolkit / desktop environment level of platform.
And we'll use PLATFORM(CAIRO), PLATFORM(CG), and whatever else is
needed for graphics toolkit dependencies that aren't necessarily
strictly tied to a corresponding OS or desktop environment.
We're trying to keep subdirectory names in sync with the PLATFORM
Most platform-specific code will be in subdirectories of platform,
for things used by the engine; or in platform-specific subdirectories
of bridge, for interfaces used on different platforms to build a
platform-appropriate API layer on top of WebCore.
Occasionally other directories may have platform-specific
subdirectories or files, for instance RenderThemeMac in rendering.
I hope this helps to explain the design.
