詳細描述

The QChar class provides a 16-bit Unicode character.

In Qt, Unicode characters are 16-bit entities without any markup or structure. This class represents such an entity. It is lightweight, so it can be used everywhere. Most compilers treat it like a unsigned short .

QChar provides a full complement of testing/classification functions, converting to and from other formats, converting from composed to decomposed Unicode, and trying to compare and case-convert if you ask it to.

The classification functions include functions like those in the standard C++ header <cctype> (formerly <ctype.h>), but operating on the full range of Unicode characters. They all return true if the character is a certain type of character; otherwise they return false. These classification functions are isNull () (returns true if the character is '\0'), isPrint () (true if the character is any sort of printable character, including whitespace), isPunct () (any sort of punctation), isMark () (Unicode 標記)， isLetter () (字母)， isNumber () (任意排序的數字字符，不僅僅 0-9)， isLetterOrNumber ()，和 isDigit () (decimal digits). All of these are wrappers around category () which return the Unicode-defined category of each character.

QChar 還提供 direction (), which indicates the "natural" writing direction of this character. The joining () function indicates how the character joins with its neighbors (needed mostly for Arabic) and finally hasMirrored (), which indicates whether the character needs to be mirrored when it is printed in its "unnatural" writing direction.

Composed Unicode characters (like å) can be converted to decomposed Unicode ("a" followed by "ring above") by using decomposition ().

In Unicode, comparison is not necessarily possible and case conversion is very difficult at best. Unicode, covering the "entire" world, also includes most of the world's case and sorting problems. operator==() and friends will do comparison based purely on the numeric Unicode value (code point) of the characters, and toUpper () 和 toLower () will do case changes when the character has a well-defined uppercase/lowercase equivalent. For locale-dependent comparisons, use QString::localeAwareCompare ().

轉換函數包括 unicode () (到標量)、 toLatin1 () (到標量，但將所有非 Latin-1 字符轉換成 0)、 row () (給齣 Unicode 行)、 cell () (給齣 Unicode 單元格)、 digitValue () (給齣任意多數字字符的整數值)、及大量構造函數。

QChar provides constructors and cast operators that make it easy to convert to and from traditional 8-bit char 。若有定義 QT_NO_CAST_FROM_ASCII and QT_NO_CAST_TO_ASCII ，如闡述在 QString 文檔編製，將需要明確調用 fromAscii () 或 fromLatin1 ()，或使用 QLatin1Char , to construct a QChar from an 8-bit char ，和將需要調用 toAscii () 或 toLatin1 () 以獲得 8 位值。
