想做个资源管理器,
所以要用到 CTreeCtrl,不过我用了CTreeView,但是这个重来都没有注意过样式,今天有点头大,不过还是解决了。
要想有折叠按钮,在控件创建好之后
用 SetWindowLong()去设置就好了。
SetWindowLong(GetTreeCtrl().m_hWnd,GWL_STYLE,GetWindowLong(GetTreeCtrl().m_hWnd,GWL_STYLE)|TVS_LINESATROOT |TVS_HASBUTTONS);
HASBUTTONS 有折叠按钮
TVS_HASBUTTONS
Displays plus (+) and minus (-) buttons next to parent items. The user clicks the buttons to expand or collapse a parent item’s list of child items. To include buttons with items at the root of the tree view, TVS_LINESATROOT must also be specified.
所有要改变样式的方法,都可以这样用。
