I do this.
I wish I could change the size of icons on menus
but does not appear possible with 4.5.3

void
MyApp::setAllIconSizes( QSize sz ) {
    foreach( QWidget *wp, qApp->topLevelWidgets() ) {
        foreach( QToolBar *bp, wp->findChildren<QToolBar*>() )
            bp->setIconSize( sz );
        foreach( QToolButton *bp, wp->findChildren<QToolButton*>() )
            bp->setIconSize( sz );
    }
}
