qss中设置QTreeView选中项样式

Question

我需要更改 QTreeView 上所选项目的背景颜色。我已经尝试使用 this example and this Stack Overflow 问题。

应用于 ::branch 子控件的样式工作正常，但 ::item 子控件中的 none 命令工作。

应用于QTreeView的QSS：

QTreeView {
   show-decoration-selected: 1;
}

QTreeView::item {
     border: 1px solid #d9d9d9;
    border-top-color: transparent;
    border-bottom-color: transparent;
     background: rgb(255, 0,0);
}

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);
}

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;
}

这是我的结果：

谁能帮帮我，先谢谢了。

Answer 1

您只想让您的分支选择颜色与您的项目相匹配？

QTreeView::branch:selected {
  background:
}

QTreeView::branch:selected:active {
  background:
}

QTreeView::branch:selected:!active {
  background:
}

等...

经过一番研究，我在 Qt 邮件列表中得到了答案。使用以下 QStylesheet 完成了预期的效果：

QTreeView {
    background-color: transparent;
    selection-background-color: green; /* Used on Mac */
    selection-color: white; /* Used on Mac */
    show-decoration-selected: 1;
}

QTreeView::item:selected {
    background-color: green; /* Used on Windows */
    color: white;
}

改变样式的Mac行，即使我在Windows，也不知道是我windows版本的bug，还是在也许是这个 Qt 版本。
