PLEASE QUIT harassing me about my "lack of basic knowledge" - such continuing (!) harassment just does not fit this forum purpose . ( read how to answer the question INSTRUCTIONS and follow them PLEASE ) I am just learning as I go because I believe that it is better to start with coding a real application and if it does not perform as expected then RTFM and or ask for help.

all I am asking - which way is up and WHY ?

later if you use “delete” on the pointer will that delete the content of the variable too?

Quote:

QDebug &QDebug::operator<<(QChar t)
Writes the character, t, to the stream and returns a reference to the stream. Normally, QDebug prints control characters and non-US-ASCII characters as their C escape sequences or their Unicode value (\u1234). To print non-printable characters without transformation, enable the noquote() functionality, but note that some QDebug backends may not be 8-bit clean and may not be able to represent it.

Quote:

QDebug &QDebug::noquote()
Disables automatic insertion of quotation characters around QChar, QString and QByteArray contents and returns a reference to the stream.

When quoting is disabled, these types are printed without quotation characters and without escaping of non-printable characters.
