public void handleEntryClick(final MouseEvent mouseEvent) {
if (!mouseEvent.isPopupTrigger() || !(mouseEvent.getComponent() instanceof JTree)) {
return;
}
JTree treeDir = (JTree)mouseEvent.getComponent();
final TreePath path = treeDir.getClosestPathForLocation(mouseEvent.getX(), mouseEvent.getY());
if (path == null) {
return;
}
treeDir.setSelectionPath(path);
boolean hasStream;
