Hi!
I am making an app using app designer.
There is a uitree, and I was able to create a child node of that uitree through the add button like below.
function buttonPushed(app,event)
app.TreeNode = uitreenode(app.Scenario1Node);
end
But after creating multiple nodes, I can't figure out how to remove the selected node.
What should I do?
My goal is that when creating a node, the contextmenu of the node is also created, and the contextmenu has a function to delete the selected node.
please help me! Thank you.

Hi Jae-Hee,
You can delete the node directly as follows
% Remove node of UITree
delete(app.TreeNode)
% If you want to remove only its children use
delete(app.TreeNode.Children)

To obtain the selected nodes use the SelectedNodes property of the object Tree
delete(app.Tree.SelectedNodes);
To delete a particular position of the TreeNode array use
delete(app.TreeNode.Children(3))
