public class QTextBoundaryFinder
The QTextBoundaryFinder class provides a way of finding Unicode text boundaries in a string. QTextBoundaryFinder allows to find Unicode text boundaries in a string, similar to the Unicode text boundary specification (see http://www.unicode.org/reports/tr29/tr29-11.html).
QTextBoundaryFinder can operate on a QString in four possible modes depending on the value of BoundaryType.
Units of Unicode characters that make up what the user thinks of as a character or basic unit of the language are here called Grapheme clusters. The two unicode characters 'A' + diaeresis do for example form one grapheme cluster as the user thinks of them as one character, yet it is in this case represented by two unicode code points.
Word boundaries are there to locate the start and end of what a language considers to be a word.
Line break boundaries give possible places where a line break might happen and sentence boundaries will show the beginning and end of whole sentences.
