写一个视图，里面放置一个label，设置图片

public class PlotView extends ViewPart {public static final String ID = "com.ccnt.miner.view.plot"; //$NON-NLS-1$private Label label;public PlotView() {// TODO Auto-generated constructor stub}@Overridepublic void createPartControl(Composite parent) {// TODO Auto-generated method stubComposite composite = new Composite(parent, SWT.NONE);  // 不带边框composite.setLayout(new GridLayout(1, false));label = new Label(composite, SWT.FILL);label.setImage(Activator.getImage("icons/arrowup.gif"));label.setLayoutData(new GridData(GridData.FILL_BOTH));}@Overridepublic void setFocus() {// TODO Auto-generated method stub}public void updateImage(String imagepath){//label.setImage(Activator.getImage(imagepath));label.setImage(SWTResourceManager.getImage(imagepath));//label.setImage(SWTResourceManager.getImage("d://a.png"));//用<span style="font-family: Arial, Helvetica, sans-serif;">SWTResourceManager 可以加载任意路径下的图片如C盘,D盘，</span><span style="font-family: Arial, Helvetica, sans-serif;">Activator只能加载工程下的图片</span><span style="font-family: Arial, Helvetica, sans-serif;"></span>}}

打开图片的Action操作

//值打开一个plot视图 try { IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();IViewPart vPart =page.showView(PlotView.ID);     ((PlotView)vPart).updateImage("d://icons/a.png") ;//调用视图的更新方法，用于更新视图内的表数据                  } catch (PartInitException e) {       // handle exception    }

打开多个视图

//打开多个plot视图 try { Random rand = new Random();int instanceNum = rand.nextInt(100);System.out.println("instanceNum:" + instanceNum);IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();IViewPart vPart =page.showView(PlotView.ID, Integer.toString(instanceNum), IWorkbenchPage.VIEW_ACTIVATE);     ((PlotView)vPart).updateImage(imgpath) ;//调用视图的更新方法，用于更新视图内的表数据    instanceNum++;               } catch (PartInitException e) {       // handle exception     }

plugin.xml中设置添加allowMultiple

 <view            allowMultiple="true"            class="com.ccnt.miner.view.PlotView"            id="com.ccnt.miner.view.plot"            name="Plot"            restorable="true">      </view>
