Detailed Description

The QCharRef class is a helper class for QString.

Note

This class or function is reentrant.

Warning

This function is not part of the public interface.

When you get an object of type QCharRef, if you can assign to it, the assignment will apply to the character in the string from which you got the reference. That is its whole purpose in life. The QCharRef becomes invalid once modifications are made to the string: if you want to keep the character, copy it into a QChar.

Most of the QChar member functions also exist in QCharRef. However, they are not explicitly documented here.
