header->offset = data - quintptr(header); } return header;}Q_ASSERT不用看 只是一个警告 下面的if语句第一个条件肯定满足 第二个条件仅当传入空文本才调用 这里就不分析了 下面是关键部分:size_t headerSize = sizeof(QArrayData);执行后headerSize为16 接着判断语句会执行headerSize += (alignment -...

QT中关于QString用法有：1、获取子字符串在字符串中的位置。（1）indexOf（）：返回此字符串中第一次出现的字符串str的索引位置，从索引位置向前搜索。如果找不到str，则返回－1。（2）lastIndexOf（）函数：返回字符串的最后一次出现的索引。2、字符串的追加和组合。（1）二元操作符“＋”用来组合...
