The processing below seems to be needed only for DRT. I think this section of the code should be guarded with "if (dumpFrameLoaderCallbacks)" or some other similar mechanism.

Everything inside policyDelegateEnabled is DRT specific anyway - I don't think anything else but DRT would have a use case for policyDelegateEnabled.

WebKit/qt/WebCoreSupport/FrameLoaderClientQt.cpp:165
 +  static const char* linkClickedString = "link clicked";
I suggest to leave out these variables. They will be read-write pointers to read-only memory, causing unnecessary relocations.

WebKit/qt/WebCoreSupport/FrameLoaderClientQt.cpp:174
 +  static const char* navigationTypeToString(NavigationType type)
Instead I suggest to return the strings inline here, like return "form submitted";

hmm, should this printf always be printing out things when policyDelegateEnabled is true?

WebKit/qt/WebCoreSupport/FrameLoaderClientQt.cpp:1100
 +                      static_cast<const MouseEvent*>(event);
why not just put that on one line

WebKit/qt/WebCoreSupport/FrameLoaderClientQt.cpp:1095
 +  
why a new line here

Laszlo asked the same question and I think the answer is yes - policyDelegateEnabled is a dumpCallbacks type variable set exclusively by DRT.

I still want a comment here explaining that this is only used by the DRT. You can commit if you fix that.
