94 \class QChar -

95 \inmodule QtCore -

96 \brief The QChar class provides a 16-bit Unicode character. -

97 -

98 \ingroup string-processing -

99 \reentrant -

100 -

101 In Qt, Unicode characters are 16-bit entities without any markup -

102 or structure. This class represents such an entity. It is -

103 lightweight, so it can be used everywhere. Most compilers treat -

104 it like a \c{unsigned short}. -

105 -

106 QChar provides a full complement of testing/classification -

107 functions, converting to and from other formats, converting from -

108 composed to decomposed Unicode, and trying to compare and -

109 case-convert if you ask it to. -

110 -

111 The classification functions include functions like those in the -

112 standard C++ header \<cctype\> (formerly \<ctype.h\>), but -

113 operating on the full range of Unicode characters, not just for the ASCII -

114 range. They all return true if the character is a certain type of character; -

115 otherwise they return false. These classification functions are -

116 isNull() (returns \c true if the character is '\\0'), isPrint() -

117 (true if the character is any sort of printable character, -

118 including whitespace), isPunct() (any sort of punctation), -

119 isMark() (Unicode Mark), isLetter() (a letter), isNumber() (any -

120 sort of numeric character, not just 0-9), isLetterOrNumber(), and -

121 isDigit() (decimal digits). All of these are wrappers around -

122 category() which return the Unicode-defined category of each -

123 character. Some of these also calculate the derived properties -

124 (for example isSpace() returns \c true if the character is of category -

125 Separator_* or an exceptional code point from Other_Control category). -

126 -

127 QChar also provides direction(), which indicates the "natural" -

128 writing direction of this character. The joiningType() function -

129 indicates how the character joins with it's neighbors (needed -

130 mostly for Arabic or Syriac) and finally hasMirrored(), which indicates -

131 whether the character needs to be mirrored when it is printed in -

132 it's "unnatural" writing direction. -

133 -

134 Composed Unicode characters (like \a ring) can be converted to -

135 decomposed Unicode ("a" followed by "ring above") by using decomposition(). -

136 -

137 In Unicode, comparison is not necessarily possible and case -

138 conversion is very difficult at best. Unicode, covering the -

139 "entire" world, also includes most of the world's case and -

140 sorting problems. operator==() and friends will do comparison -

141 based purely on the numeric Unicode value (code point) of the -

142 characters, and toUpper() and toLower() will do case changes when -

143 the character has a well-defined uppercase/lowercase equivalent. -

144 For locale-dependent comparisons, use QString::localeAwareCompare(). -

145 -

146 The conversion functions include unicode() (to a scalar), -

147 toLatin1() (to scalar, but converts all non-Latin-1 characters to -

148 0), row() (gives the Unicode row), cell() (gives the Unicode -

149 cell), digitValue() (gives the integer value of any of the -

150 numerous digit characters), and a host of constructors. -

151 -

152 QChar provides constructors and cast operators that make it easy -

153 to convert to and from traditional 8-bit \c{char}s. If you -

154 defined \c QT_NO_CAST_FROM_ASCII and \c QT_NO_CAST_TO_ASCII, as -

155 explained in the QString documentation, you will need to -

156 explicitly call fromLatin1(), or use QLatin1Char, -

157 to construct a QChar from an 8-bit \c char, and you will need to -

158 call toLatin1() to get the 8-bit value back. -
