RE: Glib::ustring

["Jorge Luis Vidales Valladares" <jorgevidales gmail com>]

Thanks for the int

I Look for the doc's and finally i came up with this that works

  
     Glib::ustring str;
     str = m_Entry1.get_text();
     locale_from_utf8 (str);

     const char *szMessage= str.c_str();
  
     int nBytesSent = serial.SendData(szMessage, strlen(szMessage));


Thanks again

Indeed. Because the get_text() method returns a Glib::ustring, which is
absolutely not just a char*. You need to look up the documentation on
ustring - it has a method for extracting a char* from it. I think it's
called c_str() but I may be getting confused with std::string or
Borland's VCL AnsiString and I don't have a web browser on this box to
check the GTKmm docs.

Incidentally, it works the other way, passing a char* when a
Glib::ustring is wanted, because Glib::ustring provides a constructor
that takes a char* argument. The compiler knows that:

   MethodThatTakesUString ( "hello" );

is a short-hand for:

   MethodThatTakesUString ( Glib::ustring("hello") );
