Add and delete Tree nodes with context menu in app designer

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)

[Jae-Hee Park]

when I want to delete just one Children Node, how can I select that node and delete?

[Alberto Cuadra Lara]

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))
