How to change QTreeView Selection background on Indicators (branch)?

[BDC_Patrick]

Hi there..

I managed to change the Indicators of children in a TreeView to this:

Now, i want to select an Item.. so:

Now.. how can i get rid of this white box.. and make it
A - transparent..
or if possible
B - part of the whole blue selection?

The whole part of the qss file, of this Widget:

QTreeView {
    border: 2px solid #373737;
    alternate-background-color: transparent;
    show-decoration-selected: 0;
    background: url(:/Files/img/Tile_FlipFlop_Dark.png) 0;
    selection-background-color: transparent;
}

QTreeView::branch:has-siblings:!adjoins-item {
    border-image: url(:/Files/img/TreeArrow_vlineHalf.png) 0;
    selection-background-color: transparent;
}

QTreeView::branch:has-siblings:adjoins-item {
    border-image: url(:/Files/img/TreeArrow_more.png) 0;
    selection-background-color: transparent;
}

QTreeView::branch:!has-children:!has-siblings:adjoins-item {
    border-image: url(:/Files/img/TreeArrow_end.png) 0;
    selection-background-color: transparent;
}

QTreeView::branch:has-children:!has-siblings:closed,
QTreeView::branch:closed:has-children:has-siblings {
    border-image: none;
    image: url(:/Files/img/TreeArrow_closed.png);
    selection-background-color: transparent;
}

QTreeView::branch:open:has-children:!has-siblings,
QTreeView::branch:open:has-children:has-siblings  {
    border-image: none;
    image: url(:/Files/img/TreeArrow_open.png);
    selection-background-color: transparent;
}

QTreeView::item:selected {
    background-color: #547cc5;
    border: 1px solid #4e78a1;
    selection-background-color: transparent;
}

QTreeView::branch,
QTreeView::branch:selected,
QTreeView::branch:selected:active,
QTreeView::branch:selected:!active {
    alternate-background-color: transparent;
    background-color: transparent;
    border-color: transparent;
    background: none;
    selection-background-color: transparent;
}

Hi, I think you could try to play with QStyleOptionViewItem::showDecorationSelected or see how it's done in KDE Ark
