SampleTree demonstrates JTree features. Each node of SampleTree has 7 children, with each one drawn in a random font and color. Each node is named after its font. While the data isn't interesting, the example illustrates a number of features:

• Dynamically loading children (see DynamicTreeNode.java)
• Adding/removing/inserting/reloading (see the following inner classes in SampleTree.java: AddAction, RemoveAction, InsertAction, and ReloadAction)
• Creating a custom cell renderer (see SampleTreeCellRenderer.java)
• Subclassing JTreeModel for editing (see SampleTreeModel.java)

To run the SampleTree demo:

java -jar SampleTree.jar
