QTreeWidget设置stylesheet的一个问题
背景设成了黑色。

树中可以收起展开的父节点的那个小三角怎么改样式表?想把颜色改成白色的。
[解决办法]

QTreeView::branch:has-siblings:!adjoins-item {
border-image: url(vline.png) 0;
}

QTreeView::branch:has-siblings:adjoins-item {
border-image: url(branch-more.png) 0;
}

QTreeView::branch:!has-children:!has-siblings:adjoins-item {
border-image: url(branch-end.png) 0;
}

QTreeView::branch:has-children:!has-siblings:closed,
QTreeView::branch:closed:has-children:has-siblings {
border-image: none;
image: url(branch-closed.png);
}

QTreeView::branch:open:has-children:!has-siblings,
QTreeView::branch:open:has-children:has-siblings {
border-image: none;
image: url(branch-open.png);
}
