Question TreeView connected Lines

Hi,

what would be my best approch to implement "lines" in the Runtime TreeView?
I tried to search for it, but i didnt find an awnser.

Currently i have this:


I would like to replace the teal Areas with something like this:



2. Question: Do the Entries/Elements know about if they are "the last of current indentation" or any other Information i could use to code something up myself?

 

Alright, nevermind. I found a way.



Solution: the individual Elements have 2 addition absolutly positioned images to the left of them. Binding i run a check if they are the last element in their Parents list. Like this:

Code (CSharp):

1. ...
2. else if (treeV.GetItemDataForIndex<object>(index) is sdGalaxy g)
3.                 {
4.                     plListEntry.sLabel.text = g.Name;
5.                     plListEntry.sToggle.visible = false;
6.                     plListEntry.sImageVisualElement.style.backgroundImage = icon_galaxy;
7.                     //plListEntry.parent.parent.style.left = -15;
8.  
9.                     if (g.Sectors.Count > 0)
10.                     {
11.                         plListEntry.sVisualElementTreeTrunk.visible = false;
12.                         plListEntry.sVisualElementTreeTrunk_L.visible = false;
13.                     }
14.                     else
15.                     {
16.                         if (g.Parent.Galaxies.IndexOf(g) == g.Parent.Galaxies.Count - 1)
17.                         {
18.                             plListEntry.sVisualElementTreeTrunk.visible = false;
19.                             plListEntry.sVisualElementTreeTrunk_L.visible = true;
20.                         }
21.                         else
22.                         {
23.                             plListEntry.sVisualElementTreeTrunk_L.visible = false;
24.                             plListEntry.sVisualElementTreeTrunk.visible = true;
25.                         }
26.                     }
27.                 }
28. ...

This simple implementation is ok for now. I just hope that i dont come in problems with the virtualizer, because i cant be 100% sure if what is the last element in the object list is also the "most bottom" element of the indent for the virtualized tree.
