Bug 29233 – Add ENABLE(DRAG_SUPPORT)

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Greg Bolsinga]

Wrap dragging code in an ENABLE wrapper. This is for platforms (such as
iPhone) that do not support drag and drop.

Implements the fix

This will compile and link Mac OS X without drag and drop support.

Of course Mac OS X (and many other platforms) will never ship in this
configuration, so should the Mac code really be conditionally compiled for this?

iPhone ships with this code off; the goal is to get more iPhone changes into webkit.org.

It doesn't make sense to include this in both wtf/Platform.h and FeatureDefines.xcconfig.  Given that it's a platform difference and not a feature, the former makes much more sense.

Address Mark's comments.

Removes the FeatureDefines.xcconfig changes, and the build-webkit changes,
since this is Platform related as well.

Fix DerivedSources.make for all platforms

Similar to the work done for the CONTEXT_MENU patch.

[Greg Bolsinga]

This is being conditionalized because it is not compiled for iPhone.

Please add a blank line after the "#if ENABLE(.." statement and before the "#endif // ..." statement.

Ditto for blank lines.  Adding a comment for the "}" used to end the WebCore namespace would be nice, too, but not necessary.

As we discussed offline, please leave these changes out.  It doesn't make sense to disable context menu support for code in WebKit/mac.  When WebKit code for iPhone lands, it will be refactored or moved instead of shared within WebKit/mac.  (Note that mac-specific files in WebCore are needed to prevent excessive use of EXCLUDED_SOURCE_FILE_NAMES in Xcode.)
