Subject: [Qt-interest] howto convert QString to char*

 

I am using the following:

 

    char * toChar(const QString str)

    {

        QByteArray ba = str.toLatin1();

        return  ba.data();

    }

 

the bytearray contains usefull data,

however the value returned by data() is very useless.

Is this because ba is destroyed at the end of toChar?

If so, what would you recommend to make such a conversion?

 

In my code I use this to write

 

QString sendSignal = "1.23 1" // this is set somewhere else

char * str = toChar(sendSignal);

...

// dll functions requiring a char* string...

 

Matthias
