示例1: interactiveScrollPathToVisible
import org.jdesktop.swingx.treetable.TreeTableModel; //导入方法依赖的package包/类
/**
* issue #296-swingx: expose scrollPathToVisible in JXTreeTable.
*
* Treetable should behave exactly like Tree - so
* simply passing through to the hierarchical renderer is not quite
* enough - need to force a scrollTo after expanding.
* Not really: all scrolling is piped through scrollRectToVisible,
* so that looks like the central place to fix (f.i. delegate to
* the enclosing treeTable). Related issue #575-swingx.
*
* note: the action is not guarded against overshooting
* at the end of the model!
