MATLAB: Calling node from treenode without using selectednodes

app designerMATLABnodetreenode

hello,

I am working on app designer. in my app I created a treenode to store data from various places. in a different part of the app I have a dropdown to select which node I want. Once I chose the node there's a button that would display the nodes data in a table. However whenever I click the button the node isn't recognized no matter what I do. is there a way to call a created node without using selectednodes?

Best Answer

it can be done by indexing the nodes

MATLAB: How to delete nodes from a “uitree”

To remove a single node from a "uitree", simply call its built-in 'delete' method. For example, if the node you want to delete is called 'app.node', you can delete it using this command:

>> app.node.delete;

If you want to delete all the nodes in a tree, you need to first take the list of all nodes (stored as the 'Children' property of the tree), then call the delete method on that list. If the tree that you want to clear is called 'app.Tree', the following commands will delete all of its nodes:

>> a = app.Tree.Children;
>> a.delete;
