[swing] - TreeTable sample

- 결과화면

sun 에 기고된 기사를 토대로 따라 하다가 좀더 쉽게.. 사용하기 편한 예제를 만들어 보자는 취지로 만들게 됨.


1. DefaultMutableTreeNode 를 사용해서 트리노드를 만들다.
2. 생성된 노드로 TreeTableModel 을 만든다.
3. 데이터부가 완성되면 JTreeTable 을 생성하고
4. 여기서.. 아무 생각없이 (Netbeans 만 사용하다보니.. 사악한 마법사 땜시 고생함.) add 시켰다가 낭패봄.

    setViewportView() 사용해서 화면에 TreeTable을 보여줌.

// 1번.
DefaultMutableTreeNode root = getTreeNode();

// 2번.
TreeTableModel model = new BookTreeTableModel(root);

// 3번.
JTreeTable treeTable = new JTreeTable(model);

// 4번.
treeTableScrollPane.setViewportView(treeTable);
 
// TreeTable top-level container 배경색 변경.
treeTable.getParent().setBackground(Color.white);

 나머지 잡다한 코드들..

// 1번.
