QScrollArea removes the space between the content of the area and the scrollbar.

I have a problem with QScrollArea.

In particular, I cannot find the correct QSS rule to remove the 3px space between the QSrollArea QFrame and the QScroll.

The space I would like to remove is the one that the red arrow points to in the picture. I also added a blue border to the inner QFrame QSrollArea, but it seems to end up correctly.

I am using QT 4.8.5 on SLED 11 SP2 (under GNOME).

My QSS looks like this:

QScrollArea {
    background: transparent;
}

QScrollArea > QWidget > QWidget
{
    background: transparent;
    border: 1px solid black;
    margin: 0px 0px 0px 0px;
}    

QScrollBar:horizontal
{
    border: 1px solid #999999;
    background:white;
    height:7px;
    margin: 0px 0px 0px 0px;
    padding: 0px 0px 0px 0px;
}

QScrollBar::handle:horizontal {
    background: qlineargradient(x1:0, y1:0, x2:1, y2:0, stop: 0  rgb(32, 47, 130), stop: 0.5 rgb(32, 47, 130),  stop:1 rgb(32, 47, 130));
    min-width: 20px;
}

QScrollBar::add-line:horizontal {
    background: qlineargradient(x1:0, y1:0, x2:1, y2:0, stop: 0  rgb(32, 47, 130), stop: 0.5 rgb(32, 47, 130),  stop:1 rgb(32, 47, 130));
    height: 0px;
    subcontrol-position: right;
    subcontrol-origin: margin;
}

QScrollBar::sub-line:horizontal {
    background: qlineargradient(x1:0, y1:0, x2:1, y2:0, stop: 0  rgb(32, 47, 130), stop: 0.5 rgb(32, 47, 130),  stop:1 rgb(32, 47, 130));
    height: 0px;
    subcontrol-position: left;
    subcontrol-origin: margin;
}

      

        
        
        
      

    

Any ideas?

Thank.
