QPainter.fillRect not filling what I tell it to

[chezifresh]

I'm not sure if this is better or not but here's what I ended up with:

Widget::Widget(QWidget *parent) :
        QWidget(parent), _brush(Qt::red)
{
... 
_lineEdit->installEventFilter(this);
}
 
void Widget::eventFilter(QObject *obj, QEvent * event){
    if(obj == _lineEdit && (event->type() == QEvent::FocusIn || event->type() == QEvent::FocusOut))
        update();
    return False;
}

Widget::Widget(QWidget *parent) :
        QWidget(parent), _brush(Qt::red)
{
... 
_lineEdit->installEventFilter(this);
}

void Widget::eventFilter(QObject *obj, QEvent * event){
    if(obj == _lineEdit && (event->type() == QEvent::FocusIn || event->type() == QEvent::FocusOut))
        update();
    return False;
}

To copy to clipboard, switch view to plain text mode 

I also ended up changing the widget around a bit, now its a scroll area with a custom viewport which has line edit inside of it, so I'm not sure if this works with my original setup, either way, these all appear to work for various problems
