{
    connect(dialognew,SIGNAL(accepted()),this,SLOT(addnew()));
}

MainWindow::addnew(){
    Form *form = new Form;
    QListWidgetItem *LWI = new QListWidgetItem(ui->listWidgetDownloading);
    ui->listWidgetDownloading->setItemWidget(LWI,form);
    LWI->setSizeHint(QSize(1200,30));
    ui->listWidgetDownloading->addItem(LWI);
    connect(form,SIGNAL(downloadFinish()),this,SLOT(moveToDownloaded()));
}

Form::download(QString surl){
    emit downloadFinish();
}

You're making the connection after you emit the signal. By default the connection is done with Qt::AutoConnection, which expands to Qt::DirectConnection in single threaded environment. Additionally, you should move to Qt 5 and its connection syntax.
