QScintilla突出显示匹配词

Question

我试图在编辑器上高亮显示所有匹配的单词，但似乎找不出如何正确高亮文本。我可以成功地循环所有找到的匹配，但似乎找不到正确的调用来突出显示它。这是我的代码：

bool found = true;  

while(found)
{
    editor->getCursorPosition(&line, &index);

    qDebug() << "line: " << line << " index: " << index;

    found = editor->findFirst(pattern, use_regular_expression, is_case_sensitive, match_whole_word_only, use_wrap, search_forward);

    if(found)
    {
        int start = editor->positionFromLineIndex(line, index);
        int end = editor->positionFromLineIndex(line, index + pattern.length());

        qDebug() << "line: " << line << " start: " << start << " end: " << end;

        // Attempts to highlight
        editor->SendScintilla(QsciScintilla::SCI_INDICGETSTYLE, QsciScintilla::INDIC_BOX);
        editor->SendScintilla(QsciScintilla::SCI_INDICSETFORE, 0x007f00);
        //child[0]->SendScintilla(QsciScintilla::SCI_INDICATORFILLRANGE, start, end - start);
        editor->SendScintilla(QsciScintilla::SCI_INDICATORFILLRANGE, start, end - start);
        editor->setIndicatorForegroundColor(QColor(159, 144, 0));
      //  editor->setColor(QColor(159, 144, 0));**
    }
}

我的qDebug()是指它遍历每一行，找到匹配项和单词出现的位置。但是注释/试图突出显示的代码是我似乎搞不清楚的地方。有什么建议吗？

你可以试试。

SendScintilla(QsciScintillaBase::SCI_INDICSETSTYLE,0, INDIC_BOX);

QString docText = text();
int end = docText.lastIndexOf(findText);
int cur = -1; 

if(end != -1) {

   while(cur != end) {
        cur = docText.indexOf(findText,cur+1);`
        SendScintilla(QsciScintillaBase::SCI_INDICATORFILLRANGE,cur,
            findText.length());
   }
}
