-    @class wxLog
+    @class wxLogFormatter

 
 

-    wxLog class defines the interface for the @e log targets 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.
+    wxLogFormatter class is used to format the log messages. It implements the
+    default formatting and can be derived from to create custom formatters.

 
 

-    Otherwise, it is completely hidden behind the @e wxLogXXX() functions and
-    you may not even know about its existence.
+    The default implementation formats the message into a string containing
+    the time stamp, level-dependent prefix and the message itself.

 
 

-    @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.
+    To change it, you can derive from it and override its Format() method. For
+    example, to include the thread id in the log messages you can use
+    @code
+        class LogFormatterWithThread : public wxLogFormatter
+        {
+            virtual wxString Format(wxLogLevel level,
+                                    const wxString& msg,
+                                    const wxLogRecordInfo& info) const
+            {
+                return wxString::Format("[%d] %s(%d) : %s",
+                    info.threadId, info.filename, info.line, msg);
+            }
+        };
+    @endcode
+    And then associate it with wxLog instance using its SetFormatter(). Then,
+    if you call:

 
 

+    @code
+        wxLogMessage(_("*** Application started ***"));
+    @endcode

 
 

-    @section log_derivingyours Deriving your own log target
+    the log output could be something like:

 
 

-    There are several methods which may be overridden in the derived class to
-    customize log messages handling: DoLogRecord(), DoLogTextAtLevel() and
-    DoLogText().
+    @verbatim
+        [7872] d:\testApp\src\testApp.cpp(85) : *** Application started ***
+    @endverbatim

 
 

-    The last method is the simplest one: you should override it if you simply
-    want to redirect the log output elsewhere, without taking into account the
-    level of the message. If you do want to handle messages of different levels
-    differently, then you should override DoLogTextAtLevel().
+    @library{wxbase}
+    @category{logging}

 
 

-    Finally, if more control over the output format is needed, then the first
-    function must be overridden as it 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).
+    @see @ref overview_log

 
 

-    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).
+    @since 2.9.4

+class wxLogFormatter
+{
+public:
+    /**
+        The default ctor does nothing.
+    */
+    wxLogFormatter();

 
 

-    Flush() shows them all and clears the buffer contents.
-    This function doesn't do anything if the buffer is already empty.

 
 

-    @see FlushActive()
+    /**
+        This function creates the full log message string.

 
 

+        Override it to customize the output string format.

+        @param info
+            All the other information (such as time, component, location...)
+            associated with this log record.

 
 

-    Notice that the use of log trace masks is hardly necessary any longer in
-    current wxWidgets version as the same effect can be achieved by using
-    different log components for different log statements of any level. Please
-    see @ref overview_log_enable for more information about the log components.

-    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.
+protected:
+    /**
+        This function formats the time stamp part of the log message.

 
 

-    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.
+        Override this function if you need to customize just the time stamp.

 
 

-    For example,
-    @code
-    wxLogTrace( wxTRACE_OleCalls, "IFoo::Bar() called" );
-    @endcode
+        @param time

+    virtual wxString FormatTime(time_t time) const;
+};

 
 

-    @code
-    wxLog::AddTraceMask( wxTRACE_OleCalls);
-    @endcode

 
 

-    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.

-
-    @section log_target Manipulating the log target
-
-    The functions in this section work with and manipulate the active log

-
-    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.
