## Detailed Description

This class represents a background log window: to be precise, it collects all log messages in the log frame which it manages but also passes them on to the log target which was active at the moment of its creation.

This allows you, for example, to show all the log messages in a frame but still continue to process them normally by showing the standard log dialog.

## Public Member Functions
| wxLogWindow (wxWindow *pParent, const wxString &szTitle, bool show=true, bool passToOld=true)
| Creates the log frame window and starts collecting the messages in it.
wxFrame * | GetFrame () const
| Returns the associated log frame window.
virtual bool | OnFrameClose (wxFrame *frame)
| Called if the user closes the window interactively, will not be called if it is destroyed for another reason (such as when program exits).
virtual void | OnFrameDelete (wxFrame *frame)
| Called right before the log frame is going to be deleted: will always be called unlike OnFrameClose().
void | Show (bool show=true)
| Shows or hides the frame.
Public Member Functions inherited from wxLogInterposer
| wxLogInterposer ()
| The default constructor installs this object as the current active log target.
Public Member Functions inherited from wxLogChain
| wxLogChain (wxLog *logger)
| Sets the specified `logger` (which may be NULL) as the default log target but the log messages are also passed to the previous log target if any.
virtual | ~wxLogChain ()
| Destroys the previous log target.
void | DetachOldLog ()
| Detaches the old log target so it won't be destroyed when the wxLogChain object is destroyed.
wxLog * | GetOldLog () const
| Returns the pointer to the previously active log target (which may be NULL).
bool | IsPassingMessages () const
| Returns true if the messages are passed to the previously active log target (default) or false if PassMessages() had been called.
void | PassMessages (bool passMessages)
| By default, the log messages are passed to the previously active log target.
void | SetLog (wxLog *logger)
| Sets another log target to use (may be NULL).
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.

## Constructor & Destructor Documentation

wxLogWindow::wxLogWindow | ( | wxWindow * | pParent,
|  | const wxString & | szTitle,
|  | bool | show = `true`,
|  | bool | passToOld = `true`
| ) |  |

Creates the log frame window and starts collecting the messages in it.

Parameters

  pParent | The parent window for the log frame, may be NULL
  szTitle | The title for the log frame
  show | true to show the frame initially (default), otherwise Show() must be called later.
  passToOld | true to process the log messages normally in addition to logging them in the log frame (default), false to only log them in the log frame. Note that if no targets were set using wxLog::SetActiveTarget() then wxLogWindow simply becomes the active one and messages won't be passed to other targets.

## Member Function Documentation

wxFrame* wxLogWindow::GetFrame | ( |  | ) | const

Returns the associated log frame window.

This may be used to position or resize it but use Show() to show or hide it.

virtual bool wxLogWindow::OnFrameClose | ( | wxFrame * | frame | ) |
| virtual

Called if the user closes the window interactively, will not be called if it is destroyed for another reason (such as when program exits).

Return true from here to allow the frame to close, false to prevent this from happening.

See Also
  OnFrameDelete()

virtual void wxLogWindow::OnFrameDelete | ( | wxFrame * | frame | ) |
| virtual

Called right before the log frame is going to be deleted: will always be called unlike OnFrameClose().

void wxLogWindow::Show | ( | bool | show = `true` | ) |

Shows or hides the frame.
