qt 用setHtml生成pdf怎么换行

Question

while (!in.atEnd())
{
message =message+'\n'+in.readLine();
}
textDocument->setHtml(message);
textDocument->print(&printer_text);
file.close();

为什么运行的结果是数据都显示在pdf的同一行呢，怎么让它换行呢

Answer 1

message =message+'\n'+in.readLine();
->

 message =message+'<br />\n'+in.readLine();
