怎样将JTree的handle图标改掉，以及出现如下横线的效果：

Question

tree.setClientProperty("JTree.lineStyle","Angled")

Answer 1

tree.setClientProperty("JTree.lineStyle","Angled")

Answer 2

jdk2的说明中JTree没有这个方法.....书都快翻烂了
是在那一个路径底下？

Answer 3

最好装个jbuild，他的帮助很好
例：
   DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();
    renderer.setOpenIcon(new ImageIcon("images/tree_open.gif"）);
    renderer.setLeafIcon(new ImageIcon("images/tree_leaf.gif"));
    renderer.setClosedIcon(new ImageIcon("images/tree_close.gif"));
    renderer.setTextSelectionColor(Color.red);
    renderer.setBackgroundSelectionColor(tree.getBackground());
    renderer.setBorderSelectionColor(tree.getBackground());
    tree.setCellRenderer(renderer);
    tree.putClientProperty("JTree.lineStyle", "Angled");

Answer 4

TMD!!!!
《ｊａｖａ2 图形设计：卷II:Ｓｗｉｎｇ〉的setClientProperty应为putClientProperty.
害人不浅.

Answer 5

还有问题：handle图标改不动,.setOpenIcon,setClosedIcon是设置枝节点的，不是
枝、叶前的handle的图标的方法.
