FYI, Qt only supports connecting to a single X server display.

This can be done by passing the return value of QDesktopWidget::screen() as 
the parent to QWidget. For example, to place a QMainWindow on screen 1 
(instead of the default which is usually screen 0), do this:

QMainWindow *mainWindow = new QMainWindow(QDesktopWidget::screen(1));
