CMyRedirector Class Reference

Detailed Description

This auxiliary class redirects the output sent to a streambuf to a wxTextCtrl object.

Uses code from http://www.devmaster.net/forums/showthread.php?t=7037 Jose Luis Blanco - Dec 2007 NOTE (10-Aug-2009): Added thread-safe support: We cannot write in a wxTextCtrl from a thread different than the main wx one, so if this object will be used by several threads, set "m_threadSafe" to true. In this mode, the object will NEVER write the text to the text control, unless the method "dumpNow()" is explicitly called FROM THE MAIN THREAD.
