-    As for the (real) trace messages, their handling depends on the settings of
-    the (application global) @e trace mask which can either be specified using
-    SetTraceMask(), GetTraceMask() and wxLogTrace() which takes an integer mask
-    or using AddTraceMask() for string trace masks.
+    As for the (real) trace messages, their handling depends on the currently
+    enabled trace masks: if AddTraceMask() was called for the mask of the given
+    message, it will be logged, otherwise nothing happens.

 
 

-    The difference between bit-wise and string trace masks is that a message using
-    integer trace mask will only be logged if all bits of the mask are set in the
-    current mask while a message using string mask will be logged simply if the
-    mask had been added before to the list of allowed ones.

     For example,
     For example,

-
-    @code
-    wxLogTrace( wxTraceRefCount|wxTraceOleCalls, "Active object ref count: %d", nRef );
-    @endcode
-
-    will do something only if the current trace mask contains both @c wxTraceRefCount
-    and @c wxTraceOle, but:
-

     @code
     wxLogTrace( wxTRACE_OleCalls, "IFoo::Bar() called" );
