[static] QString QString::fromAscii(const char *str, int size = -1)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Returns a QString initialized with the first size characters from the string str.

If size is -1 (default), it is taken to be strlen(str).

This function does the same as fromLatin1().

See also toAscii(), fromLatin1(), fromUtf8(), and fromLocal8Bit().

[static] QString QString::fromAscii(const QByteArray &str)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This is an overloaded function.

Returns a QString initialized with the string str.

This function was introduced in Qt 5.0.

QString &QString::sprintf(const char *cformat, ...)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Use asprintf(), arg() or QTextStream instead.

QByteArray QString::toAscii() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Returns an 8-bit representation of the string as a QByteArray.

This function does the same as toLatin1().

Note that, despite the name, this function does not necessarily return an US-ASCII (ANSI X3.4-1986) string and its result may not be US-ASCII compatible.

See also fromAscii(), toLatin1(), toUtf8(), toLocal8Bit(), and QTextCodec.

QString &QString::vsprintf(const char *cformat, va_list ap)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Use vasprintf(), arg() or QTextStream instead.
