QString to char* conversion

Question

I was trying to convert a QString to char* type by the following methods, but they don\'t seem to work.

//QLineEdit *line=new QLineEdit();{just to describe w

David's answer works fine if you're only using it for outputting to a file or displaying on the screen, but if a function or library requires a char* for parsing, then this method works best:

// copy QString to char*
QString filename = "C:\dev\file.xml";
char* cstr;
string fname = filename.toStdString();
cstr = new char [fname.size()+1];
strcpy( cstr, fname.c_str() );

// function that requires a char* parameter
parseXML(cstr);
