Multiple QNetworkAccessManager requests.

[Diath]

Hello QtCentre community. I wanted to make an application that would connect through proxy to several hosts and check which hosts have banished the proxy.
At first I thought of making an UI in Qt and connection checks in cURL but then I found out that Qt has QNetworkAccessManager so I decided to use this instead.
It actually works fine with one host - connects, waits for response, returns state. But if I run multiple checks from a loop it returns a state only once.
I thought of executing next "get()" in callback function after the first check is done, but I don't think it's correct solution.
Below I post my code, hopefully you guys can help me out with some solution.

checker.h:

QNetworkAccessManager *check[1024];

QNetworkAccessManager *check[1024];

checker.cpp:

void Checker::test()
{
	int count = ui->hosts->topLevelItemCount();
	if(count == 0)
	{
		QMessageBox::information(this, "Info", "Hosts list is empty.");
		return;
	}
 
	ui->progHosts->setMaximum(count);
	ui->progHosts->setValue(0);
 
	for(int i = 0; i < count; ++i)
	{
		QTreeWidgetItem *item = ui->hosts->topLevelItem(i);
		check[i] = new QNetworkAccessManager;
		check[i]->setProxy(QNetworkProxy(QNetworkProxy::HttpProxy, "somerandomproxy.org", 80));
		check[i]->get(QNetworkRequest(QUrl(item->text(0))));
		connect(check[i], SIGNAL(finished(QNetworkReply *)), this, SLOT(testCallback(QNetworkReply *)));
	}
}
 
void Checker::testCallback(QNetworkReply *reply)
{
	QTreeWidgetItem *item = ui->hosts->topLevelItem(1);
	if(!item)
		return;
 
	if(reply->error())
	{
		item->setText(2, reply->errorString());
		item->setTextColor(2, QColor(255, 0, 0));
	}
	else
	{
		item->setText(2, "OK");
		item->setTextColor(2, QColor(0, 255, 0));
	}
}

void Checker::test()
{
	int count = ui->hosts->topLevelItemCount();
	if(count == 0)
	{
		QMessageBox::information(this, "Info", "Hosts list is empty.");
		return;
	}

	ui->progHosts->setMaximum(count);
	ui->progHosts->setValue(0);

	for(int i = 0; i < count; ++i)
	{
		QTreeWidgetItem *item = ui->hosts->topLevelItem(i);
		check[i] = new QNetworkAccessManager;
		check[i]->setProxy(QNetworkProxy(QNetworkProxy::HttpProxy, "somerandomproxy.org", 80));
		check[i]->get(QNetworkRequest(QUrl(item->text(0))));
		connect(check[i], SIGNAL(finished(QNetworkReply *)), this, SLOT(testCallback(QNetworkReply *)));
	}
}

void Checker::testCallback(QNetworkReply *reply)
{
	QTreeWidgetItem *item = ui->hosts->topLevelItem(1);
	if(!item)
		return;

	if(reply->error())
	{
		item->setText(2, reply->errorString());
		item->setTextColor(2, QColor(255, 0, 0));
	}
	else
	{
		item->setText(2, "OK");
		item->setTextColor(2, QColor(0, 255, 0));
	}
}

Cheers, Diath.

@Edit:
Never mind, I've got it fixed by connection the finished() slot to a QNetworkReply.
