We do this for some apps too. It works well in the case of a single 
mainwindow/dialog. When we have a number of dialogs though we derive our 
dialogs from a base class that uses the Qt::FramelessWindowHint and manually 
sets the geometry of the dialog to fill the screen. Something like this:

BaseDlg::BaseDlg( QWidget* parent )
    : QDialog( parent, Qt::FramelessWindowHint ),
      m_desktop( new QDesktopWidget() )
{
    QRect r = m_desktop->availableGeometry();
    setGeometry( r );
    setMaximumSize( r.width(), r.height() );
    setMinimumSize( r.width(), r.height() );
}

we then also have an init() function that modifies the style sheet to show a 
background pixmap of the correct size etc. The derived dialogs then call 
init() from their constructor.

Cheers,
