用qt做一个可以展开的treeview控件

具体需求是啥啊

tkinter 可以轻松实现

你这图片也太模糊了，都看不清楚啊

提问方式不太对，需要注明自己具体是什么。

？？？

图片可以放清晰点的吗，看不清啊

 QString styleThree = "QTreeView{\
                border: 1px solid lightgray;\
        }\
        QTreeView::item {\
                height: 25px;\
                border: none;\
                background: transparent;\
                color: black;\
        }\
        QTreeView::item:hover {\
                background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,stop: 0 rgb(255, 220, 130), stop: 0.5 rgb(255, 220, 130), stop: 1.0 rgb(255, 230, 150));\
        }\
        QTreeView::item:selected {\
                background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,stop: 0 rgb(255, 200, 100), stop: 0.5 rgb(255, 230, 150), stop: 1.0 rgb(255, 240, 150));\
        }\
        QTreeView::branch:open:has-children {\
                image: url(展开时图片path);\
        }\
        QTreeView::branch:closed:has-children {\
                image: url(折叠时图片path);\
        }";
