外部刷新editor

在需要刷新的editor中写下如下方法，关于坐标我就随便写一个，只说明意思，刷新editor只需要刷新模型就行了

public void doRefresh(){
		
		ContentsModel parent = new ContentsModel();
		
		String[] str = HandleXML.getNodeValue("label");
		
		for (int i = 0; i < str.length; ++i) {

			NetunitModel child = new NetunitModel(str[i]);

			child.setConstraint(new Rectangle(5, 2, -1, -1));

			parent.addChild(child);

		} 
		viewer.setContents(parent);
	}

然后在需要刷新的地方加下如下代码

IEditorInput input = DiagramEditorInput.getInstance(); 
					
					DiagramEditor editor = (DiagramEditor) PlatformUI.getWorkbench()
							.getActiveWorkbenchWindow().getActivePage().findEditor(input);
					editor.doRefresh();
