.SH "QChar::Decomposition"
This enum type defines the Unicode decomposition attributes. See the Unicode Standard for a description of the values.
.SH "QChar::Direction"
This enum type defines the Unicode direction attributes. See the Unicode Standard for a description of the values.
.PP
In order to conform to C/C++ naming conventions "Dir" is prepended to the codes used in The Unicode Standard.
.SH "QChar::Joining"
This enum type defines the Unicode decomposition attributes. See the Unicode Standard for a description of the values.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QChar::QChar ()"
Constructs a null QChar (one that isNull()).
.SH "QChar::QChar ( char c )"
Constructs a QChar corresponding to ASCII/Latin1 character \fIc.\fR
.SH "QChar::QChar ( const QChar & c )"
Constructs a copy of \fIc.\fR This is a deep copy, if such a light-weight object can be said to have deep copies.
.SH "QChar::QChar ( int rc )"
Constructs a QChar for the character with Unicode code point \fIrc.\fR
.SH "QChar::QChar ( short rc )"
Constructs a QChar for the character with Unicode code point \fIrc.\fR
.SH "QChar::QChar ( uchar c )"
Constructs a QChar corresponding to ASCII/Latin1 character \fIc.\fR
.SH "QChar::QChar ( uchar c, uchar r )"
Constructs a QChar for Unicode cell \fIc\fR in row \fIr.\fR
.SH "QChar::QChar ( uint rc )"
Constructs a QChar for the character with Unicode code point \fIrc.\fR
.SH "QChar::QChar ( ushort rc )"
Constructs a QChar for the character with Unicode code point \fIrc.\fR
.SH "QChar::operator char () const"
Returns the Latin1 character equivalent to the QChar, or 0. This is mainly useful for non-internationalized software.
.PP
See also unicode().
.SH "QChar::Category QChar::category() const"
Returns the character category.
.PP
See also Category.
.SH "uchar QChar::cell () const"
Returns the cell (least significant byte) of the Unicode character.
.SH "uchar& QChar::cell ()"
Returns a reference to the cell (least significant byte) of the Unicode character.
.SH "QString QChar::decomposition () const"
Decomposes a character into its parts. Returns QString::null if no decomposition exists.
.SH "QChar::Decomposition QChar::decompositionTag() const"
Returns the tag defining the composition of the character. Returns QChar::Single if no decomposition exists.
.SH "int QChar::digitValue () const"
Returns the numeric value of the digit, or -1 if the character is not a digit.
.SH "QChar::Direction QChar::direction() const"
Returns the characters directionality.
.PP
See also Direction.
.SH "bool QChar::isDigit () const"
Returns whether the character is a decimal digit (Number_DecimalDigit).
.SH "bool QChar::isLetter () const"
Returns whether the character is a letter (Letter_* categories).
.SH "bool QChar::isLetterOrNumber () const"
Returns whether the character is a letter or number (Letter_* or Number_* categories).
.SH "bool QChar::isMark () const"
Returns whether the character is a mark (Mark_* categories).
.SH "bool QChar::isNull () const"
Returns TRUE if the characters is the unicode character 0x0000, ie. ASCII NUL.
.SH "bool QChar::isNumber () const"
Returns whether the character is a number (of any sort - Number_* categories).
.PP
See also isDigit().
.SH "bool QChar::isPrint () const"
Returns whether the character is a printable character. This is any character not of category Cc or Cn. Note that this gives no indication of whether the character is available in some font.
.SH "bool QChar::isPunct () const"
Returns whether the character is punctuation (Punctuation_* categories).
.SH "bool QChar::isSpace () const"
Returns whether the character is a separator character (Separator_* categories).
.SH "QChar::Joining QChar::joining() const"
This function is not supported (it may change to use Unicode character classes).
.PP
Returns information about the joining properties of the character (needed for arabic).
.SH "char QChar::latin1 () const"
Returns a latin-1 copy of this character, if this character is in the latin-1 character set. If not, this function returns 0.
.SH "QChar QChar::lower () const"
Returns the lowercase equivalent if the character is uppercase, or the character itself otherwise.
.SH "bool QChar::mirrored () const"
Returns whether the character is a mirrored character (one that should be reversed if the text direction is reversed).
.SH "QChar QChar::mirroredChar () const"
Returns the mirrored char if this character is a mirrored char, the char itself otherwise.
.SH "bool QChar::networkOrdered () \fC[static]\fR"
Returns TRUE if this character is in network byte order (MSB first), and FALSE if it is not. This is a platform-dependent property, so we strongly advise against using this function in portable code.
.SH "uchar QChar::row () const"
Returns the row (most significant byte) of the Unicode character.
.SH "uchar& QChar::row ()"
Returns a reference to the row (most significant byte) of the Unicode character.
.SH "ushort QChar::unicode () const"
Returns the numeric Unicode value equal to the QChar. Normally, you should use QChar objects as they are equivalent, but for some low-level tasks (eg. indexing into an array of Unicode information), this function is useful.
.SH "QChar QChar::upper () const"
Returns the uppercase equivalent if the character is lowercase, or the character itself otherwise.
