如何用wxpython展示一个如图所示的的树呢?
wxpython的treectrl功能可以实现。
1.首先我们可以用wxglade画前端frame界面,添加一个TreeCtrl ,或者多个TreeCtrl,添加root.每一个tree只能有一个root
self.tree_ctrl_1 = wx.TreeCtrl(self.panel_1, wx.ID_ANY) my_defect_root =self.my_tree.AddRoot("My Defect")
2.然后给设置图片list 用来给根节点和树节点放不一样的图片
self.image_list = wx.ImageList(16, 16) self.case_icon =self.image_list.Add(wx.Image("resource/image/icon/bookmark.png", wx.BITMAP_TYPE_PNG).Scale(16, 16).ConvertToBitmap()) self.folder_icon =self.image_list.Add(wx.Image("resource/image/icon/document.png", wx.BITMAP_TYPE_PNG).Scale(16, 16).ConvertToBitmap())
3.然后给树设置imagelist
self.project_tree.SetImageList(self.image_list)
#注意千万不能用AssignImageList ,这样写虽然运行没问题,但是关闭窗口时会导致crash,一定要用SetImageList
4.给每一个节点设置图片和文字
status_node =self.my_tree.AppendItem(my_defect_root, “open”) self.my_tree.SetItemImage(status_node, self.folder_icon, wx.TreeItemIcon_Normal)
5.给节点绑定双击事件
self.my_tree.Bind(wx.EVT_TREE_ITEM_ACTIVATED, self.show_defect_info) def show_defect_info(self, event): item = event.GetItem() self.my_tree.Expand(item) print(self.my_tree.GetItemText(item))
