## Detailed Description

A special version of wxLogChain which uses itself as the new log target.

It forwards log messages to the previously installed one in addition to processing them itself.

Unlike wxLogChain which is usually used directly as is, this class must be derived from to implement wxLog::DoLog and/or wxLog::DoLogString methods.

wxLogInterposer destroys the previous log target in its destructor. If you don't want this to happen, use wxLogInterposerTemp instead.

## Public Member Functions
| wxLogInterposer ()
| The default constructor installs this object as the current active log target. More...
Public Member Functions inherited from wxLogChain
| wxLogChain (wxLog *logger)
| Sets the specified `logger` (which may be nullptr) as the default log target but the log messages are also passed to the previous log target if any. More...
virtual | ~wxLogChain ()
| Destroys the previous log target. More...
void | DetachOldLog ()
| Detaches the old log target so it won't be destroyed when the wxLogChain object is destroyed. More...
wxLog * | GetOldLog () const
| Returns the pointer to the previously active log target (which may be nullptr). More...
bool | IsPassingMessages () const
| Returns true if the messages are passed to the previously active log target (default) or false if PassMessages() had been called. More...
void | PassMessages (bool passMessages)
| By default, the log messages are passed to the previously active log target. More...
void | SetLog (wxLog *logger)
| Sets another log target to use (may be nullptr). More...
Public Member Functions inherited from wxLog
wxLogFormatter * | SetFormatter (wxLogFormatter *formatter)
| Sets the specified formatter as the active one. More...
virtual void | Flush ()
| Show all pending output and clear the buffer. More...
void | LogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
| Log the given record. More...

## Additional Inherited Members
Static Public Member Functions inherited from wxLog
static void | AddTraceMask (const wxString &mask)
| Add the mask to the list of allowed masks for wxLogTrace(). More...
static void | ClearTraceMasks ()
| Removes all trace masks previously set with AddTraceMask(). More...
static const wxArrayString & | GetTraceMasks ()
| Returns the currently allowed list of string trace masks. More...
static bool | IsAllowedTraceMask (const wxString &mask)
| Returns true if the mask is one of allowed masks for wxLogTrace(). More...
static void | RemoveTraceMask (const wxString &mask)
| Remove the mask from the list of allowed masks for wxLogTrace(). More...
static void | DontCreateOnDemand ()
| Instructs wxLog to not create new log targets on the fly if there is none currently (see GetActiveTarget()). More...
static wxLog * | GetActiveTarget ()
| Returns the pointer to the active log target (may be nullptr). More...
static wxLog * | SetActiveTarget (wxLog *logtarget)
| Sets the specified log target as the active one. More...
static wxLog * | SetThreadActiveTarget (wxLog *logger)
| Sets a thread-specific log target. More...
static void | FlushActive ()
| Flushes the current log target if any, does nothing if there is none. More...
static void | Resume ()
| Resumes logging previously suspended by a call to Suspend(). More...
static void | Suspend ()
| Suspends the logging until Resume() is called. More...
static wxLogLevel | GetLogLevel ()
| Returns the current log level limit. More...
static bool | IsLevelEnabled (wxLogLevel level, wxString component)
| Returns true if logging at this level is enabled for the current thread. More...
static void | SetComponentLevel (const wxString &component, wxLogLevel level)
| Sets the log level for the given component. More...
static void | SetLogLevel (wxLogLevel logLevel)
| Specifies that log messages with level greater (numerically) than logLevel should be ignored and not sent to the active log target. More...
static bool | EnableLogging (bool enable=true)
| Globally enable or disable logging. More...
static bool | IsEnabled ()
| Returns true if logging is enabled at all now. More...
static bool | GetRepetitionCounting ()
| Returns whether the repetition counting mode is enabled. More...
static void | SetRepetitionCounting (bool repetCounting=true)
| Enables logging mode in which a log message is logged once, and in case exactly the same message successively repeats one or more times, only the number of repetitions is logged. More...
static const wxString & | GetTimestamp ()
| Returns the current timestamp format string. More...
static void | SetTimestamp (const wxString &format)
| Sets the timestamp format prepended by the default log targets to all messages. More...
static void | DisableTimestamp ()
| Disables time stamping of the log messages. More...
static bool | GetVerbose ()
| Returns whether the verbose mode is currently active. More...
static void | SetVerbose (bool verbose=true)
| Activates or deactivates verbose mode in which the verbose messages are logged as the normal ones instead of being silently dropped. More...
Protected Member Functions inherited from wxLog
virtual void | DoLogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
| Called to log a new record. More...
virtual void | DoLogTextAtLevel (wxLogLevel level, const wxString &msg)
