86 \class QTextBoundaryFinder-
87 \inmodule QtCore-
88-
89 \brief The QTextBoundaryFinder class provides a way of finding Unicode text boundaries in a string.-
90-
91 \since 4.4-
92 \ingroup tools-
93 \ingroup shared-
94 \ingroup string-processing-
95 \reentrant-
96-
97 QTextBoundaryFinder allows to find Unicode text boundaries in a-
98 string, accordingly to the Unicode text boundary specification (see-
99 \l{http://www.unicode.org/reports/tr14/}{Unicode Standard Annex #14} and-
100 \l{http://www.unicode.org/reports/tr29/}{Unicode Standard Annex #29}).-
101-
102 QTextBoundaryFinder can operate on a QString in four possible-
103 modes depending on the value of \a BoundaryType.-
104-
105 Units of Unicode characters that make up what the user thinks of-
106 as a character or basic unit of the language are here called-
107 Grapheme clusters. The two unicode characters 'A' + diaeresis do-
108 for example form one grapheme cluster as the user thinks of them-
109 as one character, yet it is in this case represented by two-
110 unicode code points-
111 (see \l{http://www.unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries}).-
112-
113 Word boundaries are there to locate the start and end of what a-
114 language considers to be a word-
115 (see \l{http://www.unicode.org/reports/tr29/#Word_Boundaries}).-
116-
117 Line break boundaries give possible places where a line break-
118 might happen and sentence boundaries will show the beginning and-
119 end of whole sentences-
120 (see \l{http://www.unicode.org/reports/tr29/#Sentence_Boundaries} and-
121 \l{http://www.unicode.org/reports/tr14/}).-
122-
123 The first position in a string is always a valid boundary and-
124 refers to the position before the first character. The last-
125 position at the length of the string is also valid and refers-
126 to the position after the last character.-
127*/-
128-
129/*!-
130 \enum QTextBoundaryFinder::BoundaryType-
131-
132 \value Grapheme Finds a grapheme which is the smallest boundary. It-
133 including letters, punctuation marks, numerals and more.-
134 \value Word Finds a word.-
135 \value Line Finds possible positions for breaking the text into multiple-
136 lines.-
137 \value Sentence Finds sentence boundaries. These include periods, question-
138 marks etc.-
139*/-
140-
141/*!-
142 \enum QTextBoundaryFinder::BoundaryReason-
143-
144 \value NotAtBoundary The boundary finder is not at a boundary position.-
145 \value BreakOpportunity The boundary finder is at a break opportunity position.-
146 Such a break opportunity might also be an item boundary-
147 (either StartOfItem, EndOfItem, or combination of both),-
148 a mandatory line break, or a soft hyphen.-
149 \value StartOfItem Since 5.0. The boundary finder is at the start of-
150 a grapheme, a word, a sentence, or a line.-
151 \value EndOfItem Since 5.0. The boundary finder is at the end of-
152 a grapheme, a word, a sentence, or a line.-
153 \value MandatoryBreak Since 5.0. The boundary finder is at the end of line-
154 (can occur for a Line boundary type only).-
155 \value SoftHyphen The boundary finder is at the soft hyphen-
156 (can occur for a Line boundary type only).-
