CoolBar

      CoolBar是一个容器，里面可以放置多个工具栏，CoolItem代表一个工具栏，基于CoolBar做出的工具栏，可以拖动，改变排放的位置。 final ViewForm vf=new ViewForm(shell, SWT.NONE);

		vf.setLayout(new FillLayout());
		
		final Text text=new Text(vf, SWT.BORDER|SWT.V_SCROLL);
		vf.setContent(text);
		
		CoolBar cb=new CoolBar(vf, SWT.NONE);
		
		
		ToolBar tb=new ToolBar(cb, SWT.NONE);
		ToolItem ti=new ToolItem(tb, SWT.PUSH);
		ti.setText("取得");
		ti.addSelectionListener(new SelectionAdapter()
		{
			@Override
			public void widgetSelected(SelectionEvent arg0) {
				// TODO Auto-generated method stub
				MessageDialog.openInformation(null, null, text.getText());
			}
			
		});
		
		
		ToolBar tb2=new ToolBar(cb, SWT.NONE);
		ToolItem ti2=new ToolItem(tb2, SWT.PUSH);
		ti2.setText("删除");
		ti2.addSelectionListener(new SelectionAdapter()
		{
			@Override
			public void widgetSelected(SelectionEvent arg0) {
				text.setText("");
			}
			
		});
		
		CoolItem ci=new CoolItem(cb, SWT.NONE);
		ci.setControl(tb);
		tb.pack();
		Point size=tb.getSize();
		ci.setSize(size);
		ci.setMinimumSize(size);
		
		
		CoolItem ci2=new CoolItem(cb, SWT.NONE);
		ci2.setControl(tb2);
		tb2.pack();
		Point size2=tb2.getSize();
		ci2.setSize(size2);
		ci2.setMinimumSize(size2);
		
		vf.setTopLeft(cb);
		
		cb.addControlListener(new ControlAdapter()
		{
			
			@Override
			public void controlResized(ControlEvent arg0) {
				vf.layout();
			}
			
		});
