I am currently using a mytreeapp function to create uitree.
The thing is all the examples I can find has less than 10 uitreenode which you have to individually define.
(ex. p1 = uitreenode(cateogry1, 'Text','A'..., p2 = uitreenode(category1, 'Text','B'...)
Is there a way I can use for loop or other loop methods to create many uitreenode? Or use other function than mytreeapp to do this?
Thank you!

Hi Danny,
Yes, you can use a loop to create multiple `uitreenode` objects programmatically. Below is an example of how you can achieve this using a for loop.
Assuming you want to create a tree with a root node and multiple child nodes.
  • Create the `uitree`
First, create the `uitree` in your figure or app.
% Create a figure
fig = uifigure('Name', 'Tree Example');
% Create a tree in the figure
tree = uitree(fig, 'Position', [20, 20, 150, 200]);
  • Create the Root Node
Create the root node of the tree.
% Create a root node
rootNode = uitreenode(tree, 'Text', 'Root Node');
  • Create Child Nodes Using a Loop
Use a for loop to create multiple child nodes under the root node.
% Number of child nodes to create
numNodes = 10;
% Loop to create child nodes
for i = 1:numNodes
% Create a child node with dynamic text
childNode = uitreenode(rootNode, 'Text', ['Node ' num2str(i)]);
end
By using loops, you can easily create multiple `uitreenode` objects programmatically, making it convenient to handle large trees without manually defining each node. This approach is flexible and can be extended to create more complex tree structures as needed.
