我需要多传一笔参数(int),可是Qt signal and slot是base on text的，不可能直接把参数绑进去
我试过QSignalMapper，可是他无法得到另外一笔参数--reply
我尝试把资料存在map中，可是此解法相当丑陋
void MainWindow::update_data(QStringList const &data)
{
int const size = data.size();
for(int i = 0; i != size; ++i)
{
QNetworkReply *reply = theme_get_->request_html(data[i]);
connect(reply, SIGNAL(finished()), this, SLOT(update_message_number()));
mapper.insert(std::make_pair(reply, i) );
}
}
void MainWindow::update_message_number()
{
auto result = theme_get_->read_html(qobject_cast<QNetworkReply *>(sender()) );
if(!result.first) qDebug() << result.second;
int const number = parser_.get_anime_live_message_number(result.second);
if(mapper.find(sender()) != mapper.end() )
anime_live_model_->set_current_message_number(mapper[sender()], number);
else
QTimer::single_shot(500, this, SLOT(update_message_number(number ) ) ); //如果map没有更新，会重复呼叫
}
请问有没有其他办法可以解决这个问题？
真希望Qt5快点出来，Qt5的signal and slot机制改了不少
