JHierarchicalList, an Extension to org.netbeans.swing.outline.Outline

My name is Viacheslav, I live in Russia, and program in Java. For several years, I've been following with interest the development of the NetBeans Platform. At work, I've been mainly working on Java EE technology, while writing something for Swing and the NetBeans Platform has been something I've been doing in my spare time.

Here I want to show a component I wrote that inherits from org.netbeans.swing.outline.Outline. It is called JHierarchicalList. In contrast to the Outline component, JHierarchicalList does not display the entire tree, but only a single path.

I'd like to add that these changes do not affect the data model, since the main work is in the class extended from javax.swing.tree.AbstractLayoutCache.

On the left, you see Outline, on the right, JHierarchicalList:

Sources are being finalized, here is the demo JAR so far. Run it as follows:

java -jar demo-hierarchical-list.jar
