How do you make a JTree using Forte for Java?

[Sonny Pondrom]

Has anyone seen a tutorial showing how to make a JTree? It is easy enough to make a JFrame, add a JScollPane and then drop a JTree into it. But that only gets you a default tree. I would like to see how to use customized TreeNode and TreeModel classes.

Hi, Sonny:
There is a good sample about JTree with the JDk distribution. Suppose you installed JDK at %JAVA_HOME%, the mentioned sample locates at %JAVA_HOME%\demo\jfc\SampleTree, run it with
java -jar SampleTree.jar
And you can get what you want.
Regards,

Thanks Guoqiao,
I found out that in the Forte IDE, if you change the "model" property in the Component Inspector to the name of your customized TreeModel, it will initialize the JTree properly.
