以下这些可能有用:
QTreeView {
alternate-background-color: yellow;
}
QTreeView {
show-decoration-selected: 1;
}
QTreeView::item {
border: 1px solid #d9d9d9;
border-top-color: transparent;
border-bottom-color: transparent;
}
QTreeView::item:hover {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #e7effd, stop: 1 #cbdaf1);
border: 1px solid #bfcde4;
}
QTreeView::item:selected {
border: 1px solid #567dbc;
}
QTreeView::item:selected:active{
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #6ea1f1, stop: 1 #567dbc);
}
QTreeView::item:selected:!active {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #6b9be8, stop: 1 #577fbf);
}
The branches of a QTreeView are styled using the ::branch subcontrol. The following stylesheet color codes the various states when drawing a branch.
QTreeView::branch {
background: palette(base);
}
QTreeView::branch:has-siblings:!adjoins-item {
background: cyan;
}
QTreeView::branch:has-siblings:adjoins-item {
background: red;
}
QTreeView::branch:!has-children:!has-siblings:adjoins-item {
background: blue;
}
QTreeView::branch:closed:has-children:has-siblings {
background: pink;
}
QTreeView::branch:has-children:!has-siblings:closed {
background: gray;
}
QTreeView::branch:open:has-children:has-siblings {
background: magenta;
}
QTreeView::branch:open:has-children:!has-siblings {
background: green;
}
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 {

}
QTreeView::branch:open:has-children:!has-siblings,
