Hi,
Can I expect that values returned by QFile::size() and
QTextStream::pos() are equal when stream at end?
It should be, but...
Or pos() of text stream can be smaller then size of file because, for
example, text stream uses 2 bytes for each character?
The documentation says "Returns the device position corresponding to the
current position of the stream", so it should account for the codec
transformations.
But since it's doing conversions along the way, there may be trouble.
Why do you want to know this? Your question screams of the X-Y problem to me.
I want to calculate progress of file reading/parsing...
Do I understand right that QTextStream::skipWhiteSpace() skips '_' and
'*' too?
You can easily test this...
"bool QChar::isSpace() const
Returns true if the character is a separator character (Separator_*
categories or certain code points from Other_Control category);
otherwise returns false."
002A;ASTERISK;Po;0;ON;;;;;N;;;;;
002D;HYPHEN-MINUS;Pd;0;ES;;;;;N;;;;;
Both have categories starting with P (Punctuation), so they're not Separator
and they're not Other_Control.
Why do you think '*' and '_' should be considered whitespace? They're not even
blank...
Because of this sentence:
Separator_* categories or certain code points from Other_Control category
And I don't know how to understand this, especially _* in the sentence...
