Thread Subject: How to create "tree view" in matlab?

Hi,

I wanted to know if it is possible to create "tree view" in matlab. Does anyone know about this?

Thanks,
Sogol

You can use the unsupported and semi-documented uitree and
uitreenode functions. Or you can integrate a Java Swing
JTree within your GUI (uitree is basically a Matlab wrapper
for JTree).

Hi,

Thanks for your help. You did really save my time!
Do you know how can I add checkboxes beside any node? and how can I change the icon of each node?

Thanks,
Sogol

Then you have to to dip into java and swing. To change icons of each node you have to implement your own java component which derives from DefaultMutableTreeNode

http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html

There are some facts you must be aware of when using java in Matlab:

Hi Sogol,
