NX二次开发-UIStyler-Tree(树)的应用(一)

采用UIStyler，开发人员可以设计出与NX风格一样的操作界面，在“开发人员”中，打开块UI样式编辑器。

添加UIStyler中的一个按钮和一个tree(树)，实现模型中体、面、边的树结构

在生成的cs中，去除.SetOnSelectHandler()的行注释。

 //------------------------------------------------------------------------------
                //Registration of Treelist specific callbacks
                //------------------------------------------------------------------------------
                //_ObjectsTree.SetOnExpandHandler(new NXOpen.BlockStyler.Tree.OnExpandCallback(OnExpandCallback));

                //_ObjectsTree.SetOnInsertColumnHandler(new NXOpen.BlockStyler.Tree.OnInsertColumnCallback(OnInsertColumnCallback));

                //_ObjectsTree.SetOnInsertNodeHandler(new NXOpen.BlockStyler.Tree.OnInsertNodeCallback(OnInsertNodecallback));

                //_ObjectsTree.SetOnDeleteNodeHandler(new NXOpen.BlockStyler.Tree.OnDeleteNodeCallback(OnDeleteNodecallback));

                //_ObjectsTree.SetOnPreSelectHandler(new NXOpen.BlockStyler.Tree.OnPreSelectCallback(OnPreSelectcallback));

                _ObjectsTree.SetOnSelectHandler(new NXOpen.BlockStyler.Tree.OnSelectCallback(OnSelectcallback));

                //_ObjectsTree.SetOnStateChangeHandler(new NXOpen.BlockStyler.Tree.OnStateChangeCallback(OnStateChangecallback));

对应的在回调函数onSelectcallback()中去除掉行注释，实现树的选择操作。

        //------------------------------------------------------------------------------
        //Treelist specific callbacks
        //------------------------------------------------------------------------------
        //public void OnExpandCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node)
        //{
        //}

        //public void OnInsertColumnCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID)
        //{
        //}

        //public void OnInsertNodecallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node)
        //{
        //}

        //public void OnDeleteNodecallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node)
        //{
        //}

        //public void OnPreSelectcallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID, bool Selected)
        //{
        //}

        public void OnSelectcallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID, bool Selected)

然后，在树中插入行：

 public void dialogShown_cb()
        {
            try
            {
                //---- Enter your callback code here -----
                NXUtilityTools.AllObjectsUnhightlight();
                _ObjectsTree.InsertColumn(1,"模型对象",240);
            }
            catch (Exception ex)
            {
                //---- Enter your exception handling code here -----
                theUI.NXMessageBox.Show("Block Styler", NXMessageBox.DialogType.Error, ex.ToString());
            }
        }

在按钮中，依次遍历对象，并按照体-->面-->顺序形成对象树：

 if (block == _TravelAllObjectsButton)
                {
                    //---------Enter your code here-----------
                    //将所有的对象存储在tree中
                    BodyCollection bodyCollection = workPart.Bodies;
                    Body[] bodies = bodyCollection.ToArray();
                    foreach(var bd in bodies)
                    {
                        Node rootNode = _ObjectsTree.CreateNode("体(" + bd.Tag.ToString() + ")");
                        _ObjectsTree.InsertNode(rootNode,null,null,Tree.NodeInsertOption.Sort);
                        Face[] faces = bd.GetFaces();
                        foreach(var fc in faces)
                        {
                            Node faceRootNode = _ObjectsTree.CreateNode("面("+fc.Tag.ToString()+")");
                            _ObjectsTree.InsertNode(faceRootNode, rootNode, null, Tree.NodeInsertOption.Sort);
                            Edge[] edges = fc.GetEdges();
                            foreach(var eg in edges)
                            {
                                Node edgeRootNode = _ObjectsTree.CreateNode("边("+eg.Tag.ToString()+")");
                                _ObjectsTree.InsertNode(edgeRootNode,faceRootNode,null,Tree.NodeInsertOption.Sort);
                            }
                        }
                    }

                }

得到如下的结果：

选择任意对象，则高亮显示这个对象，则在选择回调函数中，添加如下代码：

public void OnSelectcallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID, bool Selected)
        {
            if(tree==_ObjectsTree)
            {                
                if(Selected==true)
                {
                    string tagString = node.DisplayText.Split('(')[1].Trim(')');
                    uint tagInt = (uint)int.Parse(tagString);
                                       

                    NXObjectManager nXObjectManager = new NXObjectManager();
                    TaggedObject taggedObject = NXObjectManager.GetObjectFromUInt(tagInt);

                    if(node.DisplayText.Contains("体"))
                    {
                        Body body = (Body)taggedObject;
                        body.Highlight();
                    }
                    else if(node.DisplayText.Contains("面"))
                    {
                        Face face = (Face)taggedObject;
                        face.Highlight();
                    }
                    else if (node.DisplayText.Contains("边"))
                    {
                        Edge edge = (Edge)taggedObject;
                        edge.Highlight();
                    }

                }
                else
                {
                    NXOPENTools.General.UtilityTools.NXUtilityTools.AllObjectsUnhightlight();
                }
            }
        }
