遍历Qt富文本框架和文本块

Question

     QTextDocument *document = ui->textEdit->document();
    QTextFrame *frame = document->rootFrame();
    QTextFrame::iterator it;
    for(it = frame->begin(); it != frame->end(); ++it)
    {
        QTextFrame *childFrame = it.currentFrame();
        QTextBlock childBlock = it.currentBlock();
        if(childFrame)
            qDebug() << "frame";
        else if(childBlock.isValid())
            qDebug() << "block" <<childBlock.text();
    }

遍历文档的所有子框架和文本块
为什么这里迭代器是用.号来调用所指类对象的成员函数，而不是->符号呢。
