Problem with QHttp's data encoding.

[Diath]

So I have changed QTextStream to file.write(http->readAll()) but still after download is compile I'm not able to open the archive (Archive is corrupt~.).
Here's my current code:

void Updater::finishDownload()
{
	QFile file("Launcher.tmp");
	if( file.exists() )
		file.remove();
 
	if( !file.open(QIODevice::WriteOnly | QIODevice::Text) ) {
		QMessageBox::critical(this, "Updater", "Failed to open file.");
		return;
	}
 
	file.write(http->readAll());
	file.close();
 
	QProcess proc;
	proc.start("7z.exe", params);
 
	//file->remove();
	updateCurrentVersion();
	QMessageBox::information(this, "Updater", "New version has been downloaded.");
 
	_parent->show();
	close();
}

void Updater::finishDownload()
{
	QFile file("Launcher.tmp");
	if( file.exists() )
		file.remove();

	if( !file.open(QIODevice::WriteOnly | QIODevice::Text) ) {
		QMessageBox::critical(this, "Updater", "Failed to open file.");
		return;
	}

	file.write(http->readAll());
	file.close();

	QProcess proc;
	proc.start("7z.exe", params);

	//file->remove();
	updateCurrentVersion();
	QMessageBox::information(this, "Updater", "New version has been downloaded.");

	_parent->show();
	close();
}

To copy to clipboard, switch view to plain text mode 

Any other tips?

@Edit:
Oh, dumb me. QIODevice::Text as you said, of course. Problem solved, thanks Chris.
