Как я могу получить QSyntaxHighlighter для синтаксического выделения символов ascii, таких как @ или #? Это мой текущий код:
Highlighter::Highlighter(QTextDocument *parent)
: QSyntaxHighlighter(parent)
{
HighlightingRule rule;
keywordFormat.setForeground(Qt::darkBlue);
keywordFormat.setFontWeight(QFont::Bold);
QStringList keywordPatterns;
keywordPatterns << "\\bchar\\b" << "\\bclass\\b" << "\\bconst\\b"
<< "\\bdouble\\b" << "\\benum\\b" << "\\bexplicit\\b"
<< "\\bfriend\\b" << "\\binline\\b" << "\\bint\\b"
<< "\\blong\\b" << "\\bnamespace\\b" << "\\boperator\\b"
<< "\\bprivate\\b" << "\\bprotected\\b" << "\\bpublic\\b"
<< "\\bshort\\b" << "\\bsignals\\b" << "\\bsigned\\b"
<< "\\bslots\\b" << "\\bstatic\\b" << "\\bstruct\\b"
<< "\\btemplate\\b" << "\\btypedef\\b" << "\\btypename\\b"
<< "\\bunion\\b" << "\\bunsigned\\b" << "\\bvirtual\\b"
<< "\\bvoid\\b" << "\\bvolatile\\b" << "\\b@implementation\\b";
foreach (QString pattern, keywordPatterns) {
rule.pattern = QRegExp(pattern);
rule.format = keywordFormat;
highlightingRules.append(rule);
}
classFormat.setFontWeight(QFont::Bold);
classFormat.setForeground(Qt::darkMagenta);
rule.pattern = QRegExp("\\bQ[@-A-Za-z]+\\b");
rule.format = classFormat;
highlightingRules.append(rule);
singleLineCommentFormat.setForeground(Qt::red);
rule.pattern = QRegExp("//[^\n]*");
rule.format = singleLineCommentFormat;
highlightingRules.append(rule);
multiLineCommentFormat.setForeground(Qt::red);
quotationFormat.setForeground(Qt::darkGreen);
rule.pattern = QRegExp("\".*\"");
rule.format = quotationFormat;
highlightingRules.append(rule);
functionFormat.setFontItalic(true);
functionFormat.setForeground(Qt::blue);
rule.pattern = QRegExp("\\b[A-Za-z0-9_]+(?=\\()");
rule.format = functionFormat;
highlightingRules.append(rule);
commentStartExpression = QRegExp("/\\*");
commentEndExpression = QRegExp("\\*/");
}
Как бы я мог выделить @implementation или #include или #ifndef? Я думал о смене регулярного выражения.
