[Qt-interest] Fwd: Convert a QString to string

[chandrasekar wagmare]

also ...
QString::toLatin1() returns a QByteArray object. You store a pointer to the
internal data of that temporary object. "const char* str" is a dangling
pointer as soon as the QByteArray object goes out of scope. For more
details, see TT knowledgebase: How can I convert a QString to char* and vice
versa ? <http://trolltech.com/developer/faqs/faq.2007-01-30.9032238253>
