/**

 * This implementation assumes a "hit" for rollover if the mouse is anywhere in
 * the total width of the tree. Additionally, a pressed to the right (but
 * outside of the label bounds) is re-dispatched as a pressed just inside the
 * label bounds. This is a first go for #166-swingx.

Change cast from JXTree to JTree. Similar to how the List and Table producers work against core types. Eliminates dependency on SwingX component code.
