.SH "QChar::CombiningClass"
This enum defines names for some of the combining classes defined in the Unicode standard. See the Unicode Standard for a more detailed description.
.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 ( 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 ( const QChar & c )"
Constructs a copy of \fIc\fR. This is a deep copy, if such a lightweight object can be said to have deep copies.
.SH "QChar::QChar ( ushort 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 ( uint rc )"
Constructs a QChar for the character with Unicode code point \fIrc\fR.
.SH "QChar::QChar ( int rc )"
Constructs a QChar for the character with Unicode code point \fIrc\fR.
.SH "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 "unsigned char QChar::combiningClass () const"
Returns the combining class for the character as defined in the Unicode standard. This is mainly useful as a positioning hint for marks attached to a base character.
.PP
The Qt text rendering engine uses this information to correctly position non spacing marks around a base character.
.SH "const QString & QChar::decomposition () const"
Decomposes a character into its parts. Returns QString::null if no decomposition exists.
.SH "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 "Direction QChar::direction () const"
Returns the character's direction.
.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 character is the Unicode character 0x0000, i.e., 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 a particular font.
.SH "bool QChar::isPunct () const"
Returns whether the character is a punctuation mark (Punctuation_* categories).
.SH "bool QChar::isSpace () const"
Returns whether the character is a separator character (Separator_* categories).
.SH "bool QChar::isSymbol () const"
Returns whether the character is a symbol (Symbol_* categories)
.SH "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, otherwise returns the character itself.
.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, otherwise returns the char itself.
.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 "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 "uchar QChar::row () const"
Returns 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 (e.g. indexing into an array of Unicode information), this function is useful.
.SH "ushort & QChar::unicode ()"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Returns a reference to the numeric Unicode value equal to the QChar.
.SH "QChar QChar::upper () const"
Returns the uppercase equivalent if the character is lowercase, otherwise returns the character itself.
