Member Function Documentation

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

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 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 , ... )

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

QByteArray QString:: toAscii () const

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 )

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