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 These instructions assume that this installation's version of the java command is in your path. If it isn't, then you should either specify the complete path to the java command or update your PATH environment variable as described in the installation instructions for the Java 2 SDK.
