Inheritance diagram for wxLogStderr:

Detailed Description

This class can be used to redirect the log messages to a C file stream (not to be confused with C++ streams).

It is the default log target for the non-GUI wxWidgets applications which send all the output to stderr.

Library:  wxBase

Category:  Logging

Public Member Functions
	wxLogStderr (FILE *fp=NULL)
	Constructs a log target which sends all the log messages to the given FILE.
Public Member Functions inherited from wxLog
wxLogFormatter *	SetFormatter (wxLogFormatter *formatter)
	Sets the specified formatter as the active one.
virtual void	Flush ()
	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).
void	LogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
	Log the given record.

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().
static void	ClearTraceMasks ()
	Removes all trace masks previously set with AddTraceMask().
static const wxArrayString &	GetTraceMasks ()
	Returns the currently allowed list of string trace masks.
static bool	IsAllowedTraceMask (const wxString &mask)
	Returns true if the mask is one of allowed masks for wxLogTrace().
static void	RemoveTraceMask (const wxString &mask)
	Remove the mask from the list of allowed masks for wxLogTrace().
static void	DontCreateOnDemand ()
	Instructs wxLog to not create new log targets on the fly if there is none currently (see GetActiveTarget()).
static wxLog *	GetActiveTarget ()
	Returns the pointer to the active log target (may be NULL).
static wxLog *	SetActiveTarget (wxLog *logtarget)
	Sets the specified log target as the active one.
static wxLog *	SetThreadActiveTarget (wxLog *logger)
	Sets a thread-specific log target.
static void	FlushActive ()
	Flushes the current log target if any, does nothing if there is none.
static void	Resume ()
	Resumes logging previously suspended by a call to Suspend().
static void	Suspend ()
	Suspends the logging until Resume() is called.
static wxLogLevel	GetLogLevel ()
	Returns the current log level limit.
static bool	IsLevelEnabled (wxLogLevel level, wxString component)
	Returns true if logging at this level is enabled for the current thread.
static void	SetComponentLevel (const wxString &component, wxLogLevel level)
	Sets the log level for the given component.
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.
static bool	EnableLogging (bool enable=true)
	Globally enable or disable logging.
static bool	IsEnabled ()
	Returns true if logging is enabled at all now.
static bool	GetRepetitionCounting ()
	Returns whether the repetition counting mode is enabled.
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.
static const wxString &	GetTimestamp ()
	Returns the current timestamp format string.
static void	SetTimestamp (const wxString &format)
	Sets the timestamp format prepended by the default log targets to all messages.
static void	DisableTimestamp ()
	Disables time stamping of the log messages.
static bool	GetVerbose ()
	Returns whether the verbose mode is currently active.
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.
Protected Member Functions inherited from wxLog
virtual void	DoLogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
	Called to log a new record.
virtual void	DoLogTextAtLevel (wxLogLevel level, const wxString &msg)
	Called to log the specified string at given level.
virtual void	DoLogText (const wxString &msg)
	Called to log the specified string.
