关于 SWT Tree 的问题？？帮帮我 啊。。。

[zhang4138151]

final Composite topComposite=new Composite(shell, SWT.NONE);
RowLayout topComposite_layout=new RowLayout();
topComposite_layout.type=SWT.VERTICAL;
topComposite.setLayout(topComposite_layout);


Tree tree = new Tree(topComposite, SWT.FULL_SELECTION );
TreeItem root = new TreeItem(tree, SWT.NULL);

root.setText("root");
for (int i = 0; i < 10; i++) {
TreeItem item = new TreeItem(root, SWT.NULL);
item.setText("Item"+i);
Image find_image_xiao=new Image(item.getDisplay(),
"E:\\java\\myeclipse'workspace\\XXX_SW\\" +
"image\\test_image\\frind5hao.png");
item.setImage(find_image_xiao);
}
能成功运行的，但是tree时缩在一个很小的方块里边，只能看到一个item....

自动添加了滚动条了。。。。。

root.setSize(...);也没用啊。。。

帮帮我啊

谢谢！～～

这样改:

		shell.setLayout(new FillLayout());
		Composite topComposite = new Composite(shell, SWT.NONE);
		// RowLayout topComposite_layout = new RowLayout();
		// topComposite_layout.type = SWT.VERTICAL;
		// topComposite.setLayout(topComposite_layout);
		topComposite.setLayout(new FillLayout());

		Tree tree = new Tree(topComposite, SWT.FULL_SELECTION);
		TreeItem root = new TreeItem(tree, SWT.NULL);
		root.setText("root");
		for (int i = 0; i < 10; i++) {
			TreeItem item = new TreeItem(root, SWT.NULL);
			item.setText("Item" + i);
			 Image find_image_xiao = new Image(item.getDisplay(),
					"E:\\java\\myeclipse'workspace\\XXX_SW\\"
							+ "image\\test_image\\frind5hao.png");
			item.setImage(find_image_xiao);
		}

这样,上一个写多了.
汗ing...

		final Composite topComposite = new Composite(shell, SWT.NONE);
		// RowLayout topComposite_layout = new RowLayout();
		// topComposite_layout.type = SWT.VERTICAL;
		// topComposite.setLayout(topComposite_layout);
		topComposite.setLayout(new FillLayout());

		Tree tree = new Tree(topComposite, SWT.FULL_SELECTION);
		TreeItem root = new TreeItem(tree, SWT.NULL);
		root.setText("root");
		for (int i = 0; i < 10; i++) {
			TreeItem item = new TreeItem(root, SWT.NULL);
			item.setText("Item" + i);
			 Image find_image_xiao = new Image(item.getDisplay(),
					"E:\\java\\myeclipse'workspace\\XXX_SW\\"
							+ "image\\test_image\\frind5hao.png");
			item.setImage(find_image_xiao);
		}
