Qt4.1 Transparent Widget

[wysota]

I think the code is more or less like this:

void someWidget::resizeEvent(QResizeEvent *e){
    QWidget::resizeEvent(e);
    QRegion reg(frameGeometry());
    reg-=QRegion(geometry()); // this may have to be different here
    reg+=childrenRegion();
    setMask(reg);
}

void someWidget::resizeEvent(QResizeEvent *e){
    QWidget::resizeEvent(e);
    QRegion reg(frameGeometry());
    reg-=QRegion(geometry()); // this may have to be different here
    reg+=childrenRegion();
    setMask(reg);
}

But you could have come up to that yourself, you know...
