- 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,
-
- @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" );
@endcode
wxLog::AddTraceMask( wxTRACE_OleCalls);
@endcode
- Using string masks is simpler and allows you to easily add custom ones, so this
- is the preferred way of working with trace messages. The integer trace mask is
- kept for compatibility and for additional (but very rarely needed) flexibility
- only.
-
The standard trace masks are given in wxLogTrace() documentation.
Finally, the @e wxLog::DoLog() function automatically prepends a time stamp
standard @e strftime() function. For example, the default format is
"[%d/%b/%y %H:%M:%S] " which gives something like "[17/Sep/98 22:10:16] "
(without quotes) for the current date. Setting an empty string as the time
- format disables timestamping of the messages completely.
