Qt富文本语法高亮
1.添加新文件mysyntaxhighlighter继承QSyntaxHighlighter
#ifndef MYSYNTAXHIGHLIGHTER_H
#define MYSYNTAXHIGHLIGHTER_H#include<QSyntaxHighlighter>class MySyntaxhighlighter : public QSyntaxHighlighter
{Q_OBJECT //支持源对象系统属性
public:MySyntaxhighlighter(QTextDocument* parent = 0);
protected://重写实现该方法void highlightBlock(const QString& text);
};#endif // MYSYNTAXHIGHLIGHTER_H2.在主头文件进行语法定义 MySyntaxhighlighter *m_sLighter; //语法定义及要包含新定义的头文件
3.在mainwindow.cpp里面添加到工具栏上
m_sLighter = new MySyntaxhighlighter(ui->textEdit->document());4. 在高亮cpp里面进行实现
#include "mysyntaxhighlighter.h"MySyntaxhighlighter::MySyntaxhighlighter(QTextDocument* parent):QSyntaxHighlighter(parent)
{}void MySyntaxhighlighter::highlightBlock(const QString &text)
{QTextCharFormat format; //字符格式format.set
