QTabWidget cuts off QX11EmbedContainer a little bit?

Hello everybody,

So I have a QTabWidget that houses two other widgets, a QX11EmbedContainer and a regular QWidget.

The problem I'm having is that the tabs at the top cut off the top of the widgets they are displaying:

Hopefully this isn't a major problem.
I tried making both the QTabWidget and its childs bigger using setFixedSize(), but the children keep sticking to the top of their parent.

Code:

---

QX11EmbedContainer *container;
    QWidget *wd;
    QTabWidget *livePlayTab;
 
    livePlayTab = new QTabWidget ( this );
    livePlayTab -> setFixedSize ( 320, 320 );
    livePlayTab -> setTabPosition ( QTabWidget::North );
 
 
    container = new QX11EmbedContainer ( livePlayTab );
    container -> setFixedSize ( 320, 240 );
    container -> show();
 
    wd = new QWidget ( livePlayTab );    
    wd -> setFixedSize ( 320, 240 );
    wd -> show();
 
    livePlayTab -> addTab ( container, "Live Display" );
    livePlayTab -> addTab ( wd, "Playback" );

livePlayTab is inside a few other QGridLayouts, if that helps at all.

Putting the tabs in the south position isn't as appealing..

Does anyone know how I fix this problem?

EDIT: I think I need to look in the QStyleOptionTabWidgetFrame docs, am I right?
