Hello,

I am tracking some line nodes of type `vtkMRMLMarkupsLineNode` in a class called Plan for specific plan created by the user. How can I add those lines to the qMRMLSubjectHierarchyTreeView that I created in my custom widget?

if I set nodeType = [‘vtkMRMLMarkupsLineNode’] it correctly shows the lines only but it also shows the folder. How can I get rid of the folders if I can’t add a node to the tree view?

One last thing, How can I remove a specific node from the tree view but not from the scene?

Any help will be appreciated and thanks for your precious time.

I inspected the Data module and found out that it is using qMRMLSubjectHierarchyTreeView widget for showing the nodes in a tree view. I wanted to customize the Data module by creating my own custom widget. So I created a widget, with a combo box that selects from the list plans. The plans contains lines. I want to show the lines like a list and with all the added functionality of hide/show `eye` button, trans…
