1.1 QSS美化QTreeview代码

//设置箭头图标打开和关闭样式
"QTreeView::branch:closed:has-children:!has-siblings,QTreeView::branch:closed:has-children:has-siblings {border-image: none;image:url(:/image/UI/切图/解析硬盘/icon_spread.png);}"
"QTreeView::branch:open:has-children:!has-siblings,QTreeView::branch:open:has-children:has-siblings  {border-image: none;image: url(:/image/UI/切图/解析硬盘/icon_retract.png);}"

//设置选项样式
"QTreeView::item {background-color: transparent;}"
"QTreeView::item:hover{background-color:rgba(0,176,220,0.5);}"
"QTreeView::item:selected{background-color:rgba(0,176,220,1);}"
"QTreeView::item:selected:active{background-color:rgba(0,176,220,1);}"
"QTreeView::item:selected:!active {background-color:rgba(0,176,220,1);}"

//设置复选框样式
"QTreeView::indicator {width: 20px;height: 20px;}"
"QTreeView::indicator:enabled:unchecked {image: url(:/image/UI/切图/解析硬盘/icon_unchecked.png);}"
"QTreeView::indicator:enabled:unchecked:hover {image: url(:/image/UI/切图/解析硬盘/icon_unchecked.png);}"
"QTreeView::indicator:enabled:unchecked:pressed {image: url(:/image/UI/切图/解析硬盘/icon_unchecked.png);}"
