悬停时如何更改 QTreewidget header 背景

Question

我正在用 QTreeWidget 制作一个程序，我不知道如何在悬停时更改它的 header 背景颜色我试过但是悬停不是 working.This 是我的代码。

self.mytreeview.setStyleSheet('''
QHeaderView::section {
    background-color: qlineargradient(x1:0, y1:0, x2:0, y2:1,
                                      stop:0 #616161, stop: 0.5 #505050,
                                      stop: 0.6 #434343, stop:1 #656565);
    color: white;
    padding-left: 4px;
    border: 1px solid #6c6c6c;
}
QHeaderView::section:hover {
background-color:blue;
    border: 2px solid red;
}
QTreeView {
    show-decoration-selected: 1;
    
    outline:0;
}

QTreeView::item {
    color:#f5f6f7;
    
}

QTreeView::item:hover {
    background: rgba(80, 120, 242, 100);
    border-top:1px solid #002cf2;
    border-bottom:1px solid #002cf2;
    
    
}

QTreeView::item:selected {
    background: rgb(80, 120, 242)
}


''')
self.mytreeview.verticalScrollBar().setStyleSheet(" QScrollBar:vertical\n"
" {\n"
"     background-color: #2A2929;\n"
"     width: 15px;\n"
"     margin: 15px 3px 15px 3px;\n"
"     border: 1px transparent #2A2929;\n"

" {\n"
"     margin: 3px 0px 3px 0px;\n"
"     border-image: url(:/newPrefix/Simple_PySide_Base-master/icons/sort-up.png);\n"
"     height: 10px;\n"
"     width: 10px;\n"
"     subcontrol-position: top;\n"
"     subcontrol-origin: margin;\n"
" }\n"
"\n"

"     height: 10px;\n"
"     width: 10px;\n"
"     subcontrol-position: top;\n"
"     subcontrol-origin: margin;\n"
" }\n"
"\n"
"\n"
" QScrollBar::add-line:vertical:hover, QScrollBar::add-line:vertical:on\n"
" {\n"
"     border-image: url(:/newPrefix/Simple_PySide_Base-master/icons/sort-down-hover.png);\n"
"     height: 10px;\n"
"     width: 10px;\n"
"     subcontrol-position: bottom;\n"
"     subcontrol-origin: margin;\n"
" }\n"
"\n"
" QScrollBar::up-arrow:vertical, QScrollBar::down-arrow:vertical\n"
" {\n"
"     background: none;\n"
" }\n"
"\n"
"\n"
" QScrollBar::add-page:vertical, QScrollBar::sub-page:vertical\n"
" {\n"
"     background: none;\n"
" }")

根据@musicamante，现在我已经使用完整的样式表对其进行了编辑。一切正常，唯一的问题是悬停不影响。这可能适用于 Qtabwidget 或 QtabelWidget，但我希望它在 Qtreewidget 中。

Answer 1

QHeaderView 中的 :hover pseudo 似乎有一个强制性的要求是让部分可以点击，这对于 QTreeView 的 header 默认是不启用的。

那么，解决方法就很简单了：

    self.mytreeview.header().setSectionsClickable(True)
