NX secondary development (C#)-UIStyler-ListBox (list box) application

In the secondary development of NX, ListBox (column and table box) is a very useful block. This article mainly describes the add and delete functions of ListBox.

As shown in the figure below: Contains two blocks, object selection and list box, to achieve the "+" (add) and "X' (delete) operations on the right side of the list box.

1. Create UIStyler as shown below. Then save as .dlx and .cs

2. Build a listbox demo project in VS2019

3. The linked list uses private static List<NXObject> nXObjectsList = new List<NXObject>();; when initializing, clear the linked list and list box:

  nXObjectsList.Clear();
  string[] listBoxStrings = new string[0];
  _ListBoxUI_ObjectsListBox.SetListItems(listBoxStrings);

 

 

4. During initialization, change

               _ListBoxUI_ObjectsListBox.SetAddHandler(new NXOpen.BlockStyler.ListBox.AddCallback(AddCallback));

                _ListBoxUI_ObjectsListBox.SetDeleteHandler(new NXOpen.BlockStyler.ListBox.DeleteCallback(DeleteCallback));

Uncomment.

 

public void initialize_cb()
        {
            try
            {
                group = (NXOpen.BlockStyler.Group)theDialog.TopBlock.FindBlock("group");
                _ListBoxUI_ObjectsSelect = (NXOpen.BlockStyler.SelectObject)theDialog.TopBlock.FindBlock("_ListBoxUI_ObjectsSelect");
                group1 = (NXOpen.BlockStyler.Group)theDialog.TopBlock.FindBlock("group1");
                _ListBoxUI_ObjectsListBox = (NXOpen.BlockStyler.ListBox)theDialog.TopBlock.FindBlock("_ListBoxUI_ObjectsListBox");
                //------------------------------------------------------------------------------
                //Registration of ListBox specific callbacks
                //------------------------------------------------------------------------------
                _ListBoxUI_ObjectsListBox.SetAddHandler(new NXOpen.BlockStyler.ListBox.AddCallback(AddCallback));

                _ListBoxUI_ObjectsListBox.SetDeleteHandler(new NXOpen.BlockStyler.ListBox.DeleteCallback(DeleteCallback));

                //------------------------------------------------------------------------------
            }
            catch (Exception ex)
            {
                //---- Enter your exception handling code here -----
                theUI.NXMessageBox.Show("Block Styler", NXMessageBox.DialogType.Error, ex.ToString());
            }
        }

 

5. The code behind

 public int AddCallback(NXOpen.BlockStyler.ListBox list_box)

 public int DeleteCallback(NXOpen.BlockStyler.ListBox list_box)

Also uncomment and add the code as follows:

 //------------------------------------------------------------------------------
        //ListBox specific callbacks
        //------------------------------------------------------------------------------
        public int AddCallback(NXOpen.BlockStyler.ListBox list_box)
        {
            if(list_box==_ListBoxUI_ObjectsListBox)
            {
                TaggedObject[] taggedObjects = _ListBoxUI_ObjectsSelect.GetSelectedObjects();
                TaggedObject[] restTaggenObjects = new TaggedObject[0];
                foreach(var to in taggedObjects)
                {
                    NXObject nXObject = (NXObject)to;
                    bool isExsit = false;
                    nXObjectsList.ForEach(a =>
                    {
                        if (a.Tag == nXObject.Tag)
                            isExsit = true;
                    });
                    if(isExsit==false)
                    {
                        nXObjectsList.Add(nXObject);
                    }
                }
                string[] listBoxStrings = new string[0];
                foreach(var st in nXObjectsList)
                {
                    Array.Resize(ref listBoxStrings, listBoxStrings.Length + 1);
                    listBoxStrings[listBoxStrings.Length - 1] = st.JournalIdentifier;
                }

                _ListBoxUI_ObjectsListBox.SetListItems(listBoxStrings);
                TaggedObject[] taggedObjects1 = new TaggedObject[0];
                _ListBoxUI_ObjectsSelect.SetSelectedObjects(taggedObjects1);
                return 1;
            }
            else
            {
                return 0;
            }
        }

        public int DeleteCallback(NXOpen.BlockStyler.ListBox list_box)
        {
            if(list_box==_ListBoxUI_ObjectsListBox)
            {
                string []listBoxStrings = _ListBoxUI_ObjectsListBox.GetSelectedItemStrings();
                foreach(var lv in listBoxStrings)
                {
                    nXObjectsList.ForEach(a =>
                    {
                        if (a.JournalIdentifier == lv)
                            nXObjectsList.Remove(a);
                });
                }
                listBoxStrings = new string[0];
                foreach (var st in nXObjectsList)
                {
                    Array.Resize(ref listBoxStrings, listBoxStrings.Length + 1);
                    listBoxStrings[listBoxStrings.Length - 1] = st.JournalIdentifier;
                }

                _ListBoxUI_ObjectsListBox.SetListItems(listBoxStrings);

                return 1;
            }
            else
            {
                return 0;
            }
        }
        

After the generation is complete, it can be called.

The demonstration is as follows:
