QSS祛除QTreeView虛線框用法

祛除QTreeView的虛線框，主要在QSS中，用outline:none，用法：QTreeView{outline:none}。

1.1下面是一個具體的應用用法：

recoveryTreeView->setStyleSheet("QTreeView{background-color: transparent;color:white;font: bold 14px;outline:none;}"
                                    "QTreeView::branch:open:has-children:!has-siblings,"
                                    "QTreeView::branch:open:has-children:has-siblings {image: url(:res/recoverydata/icon/icon_list_2.png);}"
                                    "QTreeView::branch:has-children:!has-siblings:closed,"
                                    "QTreeView::branch:closed:has-children:has-siblings {image: url(:res/recoverydata/icon/icon_list_1.png);}"
                                    "QTreeView::item:hover {background-color:rgb(8,52,127);}"
                                    "QTreeView::item:selected {background-color:rgb(8,52,127);border:1px solid #08347F;}");
