How to copy uitree content in AppDesigner from app.uitree_1 to app.uitree_2?

Hello,

is there any simple (or complex) way to copy THE FULL TREE from object A (app.uitree_A) to object B (app.uitree_B)?

Seems like a reasonable feature to have, doesn't it?

Thank You!

Do you hava a solution by now by any chance?

Thanks!

I just quickly put something together:

I created one function to find the parent treeNode:

        function [Node] = searchParentNode(Node)

            Node = Node.Parent;
            if ~strcmp(Node.Type,"uitreenode")
                return
            end
            Node=searchParentNode(Node);
            
        end
        

And then a function to recursively copy the nodes

        function createRecursiveNodes(Parent, Node)
            for n = Node.Children'
                p = uitreenode(Parent, Text=n.Text, NodeData=n.NodeData, Tag=n.Tag, Icon=n.Icon);
                createRecursiveNodes(p, n);
            end
        end

Here an example:

tree = uitree(); %create a tree
%create some example nodes
parent = uitreenode(tree,Text='AAA'); 
titles = 'abc';
for i = 1:3
    uitreenode(parent,Text=titles(i), NodeData=rand(1))
end
parent = uitreenode(tree,Text='BBB'); 
titles = 'dce';
for i = 1:3
    uitreenode(parent,Text=titles(i), NodeData=rand(1))
end


TreeNodes = tree.CheckedNodes;

PNode= searchParentNode(TreeNodes(1)); %just pick any of the selected nodes and search for the UITree parent.

You can of course put as well the tree directly (it just wasnt possible in my case):

PNode = tree

then copy everything:

tree2 = uitree()
app.createRecursiveNodes(tree2,PNode); % Copy all Children recursively Top-to bottom
