NX secondary development-UIStyler-Tree (tree) application (2)

In NX secondary development-UIStyler-Tree (tree) application (1), I talked about the addition function in UIStyler-Tree, and now write down the edit and delete functions.

The first is the delete function:

a. Delete a node:

 _ObjectsTree.DeleteNode(node);

The current node and child nodes will be deleted.

b. If you want to delete the entire tree, use the following code:

                    while(_ObjectsTree.RootNode!=null)
                    {
                        _ObjectsTree.DeleteNode(_ObjectsTree.RootNode);
                    }
                    _ObjectsTree.Redraw(true);

Then there is the editing function:

a. Uncomment the following line:

                //_ObjectsTree.SetOnEndLabelEditHandler(new NXOpen.BlockStyler.Tree.OnEndLabelEditCallback(OnEndLabelEditCallback));

                _ObjectsTree.SetOnEditOptionSelectedHandler(new NXOpen.BlockStyler.Tree.OnEditOptionSelectedCallback(OnEditOptionSelectedCallback));

                _ObjectsTree.SetAskEditControlHandler(new NXOpen.BlockStyler.Tree.AskEditControlCallback(AskEditControlCallback));

                _ObjectsTree.SetOnMenuHandler(new NXOpen.BlockStyler.Tree.OnMenuCallback(OnMenuCallback)); ;

                _ObjectsTree.SetOnMenuSelectionHandler(new NXOpen.BlockStyler.Tree.OnMenuSelectionCallback(OnMenuSelectionCallback)); ;

                //_ObjectsTree.SetIsDropAllowedHandler(new NXOpen.BlockStyler.Tree.IsDropAllowedCallback(IsDropAllowedCallback));;

                //_ObjectsTree.SetIsDragAllowedHandler(new NXOpen.BlockStyler.Tree.IsDragAllowedCallback(IsDragAllowedCallback));;

 public Tree.EditControlOption OnEditOptionSelectedCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID, int selectedOptionID, string selectedOptionText, Tree.ControlType type)
        {
            if(tree==_ObjectsTree)
            {
                //type = Tree.ControlType.ComboBox;
                return Tree.EditControlOption.Accept;
            }
            else
            {
                return Tree.EditControlOption.Reject;
            }
        }

        public Tree.ControlType AskEditControlCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID)
        {           
            return Tree.ControlType.ComboBox;
        }

        public void OnMenuCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID)
        {
            TreeListMenu treeListMenu = tree.CreateMenu();          
            treeListMenu.AddMenuItem(1, "删除");
            treeListMenu.AddMenuItem(2, "编辑");
            tree.SetMenu(treeListMenu);
        }

        public void OnMenuSelectionCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int menuItemID)
        {          
            if (menuItemID == 1)
            {
                _ObjectsTree.DeleteNode(node);
                NXUtilityTools.AllObjectsUnhightlight();
            }
            if(menuItemID==2)
            {
                string[] stringArray = new string[2] {"1111","2222"};
                _ObjectsTree.SetEditOptions(stringArray,1);
            }
           
        }

        //public Node.DropType IsDropAllowedCallback(NXOpen.BlockStyler.Tree tree, NXOpen.BlockStyler.Node node, int columnID, NXOpen.BlockStyler.Node targetNode, int targetColumnID)
        //{
        //}

Realize the following functions:

1. Right click to add menu:

2. Left click on the node to pop up the combox edit box
