Images for tree branch icons in installer?

stvokr

Hi all,

I wonder if there is a way to change the images of a tree branch for the installer?
I am using a dark style sheet and the default installer branch icons are black (closed) and blue (opened) on Windows. The black branch can hardly be seen when closed.

Or is there any way to set the color? I know that the default branch color cannot be changed in a Qt application, but an image can be used instead.
But for the installer I don't know how to add the images to the installer config.

Kind regards
Oliver

Additional information:

I also tried using base64 encoded images which css supports but unfortunately not qss.

QTreeView::branch:has-children:!has-siblings:closed,
QTreeView::branch:closed:has-children:has-siblings
{
    image: url(data:image/png;base64,iVBORw0K...);
}
