@class wxLog
- wxLog class defines the interface for the @e log targets used by wxWidgets
+ wxLog class defines the interface for the <em>log targets</em> used by wxWidgets
logging functions as explained in the @ref overview_log.
+
The only situations when you need to directly use this class is when you want
to derive your own log target because the existing ones don't satisfy your
- needs. Another case is if you wish to customize the behaviour of the standard
- logging classes (all of which respect the wxLog settings): for example, set
- which trace messages are logged and which are not or change (or even remove
- completely) the timestamp on the messages.
+ needs.
- Otherwise, it is completely hidden behind the @e wxLogXXX() functions and
- you may not even know about its existence.
+ Otherwise, it is completely hidden behind the @ref group_funcmacro_log "wxLogXXX() functions"
+ and you may not even know about its existence.
@note For console-mode applications, the default target is wxLogStderr, so
that all @e wxLogXXX() functions print on @c stderr when @c wxUSE_GUI = 0.
-
- @section log_derivingyours Deriving your own log target
-
- There are two functions which must be implemented by any derived class to
- actually process the log messages: DoLog() and DoLogString().
- The second function receives a string which just has to be output in some way
- and the easiest way to write a new log target is to override just this function
- in the derived class.
-
- If more control over the output format is needed, then the first function must
- be overridden which allows to construct custom messages depending on the log level
- or even do completely different things depending on the message severity
- (for example, throw away all messages except warnings and errors, show warnings
- on the screen and forward the error messages to the user's (or programmer's) cell
- phone - maybe depending on whether the timestamp tells us if it is day or
- night in the current time zone).
-
- There also functions to support message buffering. Why are they needed?
- Some of wxLog implementations, most notably the standard wxLogGui class,
- buffer the messages (for example, to avoid showing the user a zillion of modal
- message boxes one after another -- which would be really annoying).
-
- Flush() shows them all and clears the buffer contents.
- This function doesn't do anything if the buffer is already empty.
-
- See also:
- @li Flush()
- @li FlushActive()
-
-
- @section log_tracemasks Using trace masks
-
- The functions below allow some limited customization of wxLog behaviour
- without writing a new log target class (which, aside from being a matter of
- several minutes, allows you to do anything you want).
- The verbose messages are the trace messages which are not disabled in the
- release mode and are generated by wxLogVerbose().
- They are not normally shown to the user because they present little interest,
- but may be activated, for example, in order to help the user find some program
- problem.
-
- 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.
-
- 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
-
- will log the message if it was preceded by:
-
- @code
- 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
- to all the messages. The format of the time stamp may be changed: it can be
- any string with % specifications fully described in the documentation of the
- 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 or calling the shortcut wxLog::DisableTimestamp(), disables timestamping
- of the messages completely.

- @note
- Timestamping is disabled for Visual C++ users in debug builds by
- default because otherwise it would be impossible to directly go to the line
- from which the log message was generated by simply clicking in the debugger
- window on the corresponding error message. If you wish to enable it, please
- use SetTimestamp() explicitly.
-
-
- @section log_target Manipulating the log target
-
- The functions in this section work with and manipulate the active log
- target. The OnLog() is called by the @e wxLogXXX() functions
- and invokes the DoLog() of the active log target if any.
-
- Get/Set methods are used to install/query the current active target and,
- finally, DontCreateOnDemand() disables the automatic creation of a standard
- log target if none actually exists. It is only useful when the application
- is terminating and shouldn't be used in other situations because it may
- easily lead to a loss of messages.
