给图元去掉句柄，且选中时改变图元的框子颜色

给图元去掉句柄，且选中时改变图元的边框颜色
用GEF实现过拖拽例子的朋友都应该知道拖拽用的是CustomXYLyoutEditPolicy实现的，改变图元大小也是它实现的，那么我们就在这里做文章了
首先重写CustomXYLayoutEditPolicy中的createChildEditPolicy方法，代码如下

@Override
	protected EditPolicy createChildEditPolicy(EditPart child) {
		// TODO Auto-generated method stub
		return new NeSelectionHandlesEditPolicy();
	}

然后新建NeSelectionHandlesEditPolicy继承ResizableEditPolicy，实现createSelectionHandles方法，代码如下：

@Override
	protected List<MoveHandle> createSelectionHandles() {

		final List<MoveHandle> handle = new ArrayList<MoveHandle>();

		handle.add(new MoveHandle((GraphicalEditPart) getHost()) {

			protected void initialize() {
				super.initialize();
				setBorder(new LineBorder(1) {
					public void paint(IFigure figure, Graphics graphics,
							Insets insets) {
						tempRect
								.setBounds(getPaintRectangle(figure, insets));
						if (getWidth() % 2 == 1) {
							tempRect.width--;
							tempRect.height--;
						}
						tempRect.shrink(getWidth() / 2, getWidth() / 2);
						graphics.setLineWidth(getWidth());
						if (getColor() != null)
							graphics.setForegroundColor(getColor());
						// draw roundRectangle with red color

						graphics.setAntialias(SWT.ON);
						graphics.setForegroundColor(ColorConstants.red);
						graphics.drawRectangle(tempRect);
					}
				});

				// add resize handle
//				ResizableHandleKit.addHandle((GraphicalEditPart) getHost(),
//						handle, PositionConstants.EAST);
//				ResizableHandleKit.addHandle((GraphicalEditPart) getHost(),
//						handle, PositionConstants.SOUTH);
//				ResizableHandleKit.addHandle((GraphicalEditPart) getHost(),
//						handle, PositionConstants.WEST);
//				ResizableHandleKit.addHandle((GraphicalEditPart) getHost(),
//						handle, PositionConstants.NORTH);
			}

		});

		return handle;

	}

带注释的那几行则是与句柄有关的，大家自己试试吧
