QString到Const Char *

Question

I'm trying to use the data from a function that returns a QString in a Const function that uses a Const Char*. The problem is basically the following :

int myObject::listChildProcesses([...]) const {
    // getProcessName called from : QString myObject::getProcessName() { [...] }
    const char* name = getProcessName().toLocal8Bit();
    [...]
}

Which returns :

passing 'const myObject' as 'this' argument of 'QString myObject::getProcessName()' discards qualifiers

So ... I think there is a constness problem here. However, I DO need to keep my constness in listChildProcess. Do you happen to know how I can solve that problem by keeping it ?

Answer 1

It seems that myObject::getProcessName() doesn't have a const qualifier, but called for a constant object. So you should make change its signature to QString myObject::getProcessName() const .
