[Qt-interest] QString::size()

[Jason H]

Microsoft likes to use the:

this\0
is\0
a\0
list\0
\0 <- zero length string indicating end of list

trick to give a list where only a string exists in the api.

Atlant:
 
Wanted to clarify the statement “A QString can embed '\0' characters (QChar::Null). The size() function always returns the size of the whole string, including embedded '\0' characters.“
in the document.
Even I understood that QString does not require ‘\0’ however was perplexed about the sentence.

  What ‘\0’ character? ;-)

  QStrings aren’t CStrings; they’re counted collections of UTF16 characters
  and don’t require any trailing ‘\0’ character to end them. So that string
  only contains 5 UTF16 characters.

Hi,
 
In the documentation (http://doc.qt.nokia.com/latest/qstring.html) it is mentioned that 
“A QString can embed '\0' characters (QChar::Null). The size() function always returns the size of the whole string, including embedded '\0' characters.“
And I was expecting the output as 6 (including ‘\0’) but it is 5.
QString str14 = "Apple";
qDebug()<<str14.size();  //5
 
 
Any clarification on what does the above sentence in the documentation?
 
And I thought that is the difference between QString::size() and QString::length(). But not
qDebug()<<str14.length(); //5
 
Thank You.
 
Regards,
Nandita
