QString modification.

Message 1 in thread

Hi All,

I am facing a problem.

I want to change a character in a QString at position i

for example,

func(QChar& a)
{
  this function updates QChar a;
}

QString str="Some String"
for(int i = 0 ;i < str.length; i++)
{
  func(str[i]);  //this is cannot do.
}
This throws an error: error: invalid initialization of non-const reference
of type 'QChar&' from a temporary of type 'QCharRef'

Can Any one help me???


Thanks in Advance..

Simply use QCharRef as parameter type in func(). See the docs for 
QString::operator[](int) for details.
