Try this:
@MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{

ui->setupUi(this);

QWidget *datawidget = new QWidget( this );
ui->setCentralWidget( datawidget );
datawidget->setAccessibleName("datawidget");
datawidget->setStyleSheet(" #datawidget { background-color:#000; } ");

}

MainWindow::~MainWindow()
{
delete ui;
}@

If you used a layout for your ui, you (c|sh)ould add the new widget to the layout.

Problem is with your setStyleSheet call ... use this instead

@
datawidget->setStyleSheet(" { background-color:#000; } ");
