1.创建outline
创建图形模型的 Outline 是通过 getAdapter 实现的，如果类型是 IContentOutlinePage，则返回一个大纲视图页面。因此要创建一个 MyContentOutlinePage 类。注意，这里的MyContentOutlinePage 类不是从 org.eclipse.ui.views.contentoutline.ContentOutlinePage 派生的，而是从 org.eclipse.gef.ui.parts.ContentOutlinePage 派生的。这样，MyContentOutlinePage类中使用的 TreeViewer 也是使用的 GEF 的 Editpart Viewer，所以可以保证大纲视图的内容和 Graphical Editor 的内容同步。
（1）在DiagramEditor中创建一个ContentOutlinePage的内部类，用于显示大纲视图：
1 class EditorContentOutlinePage extends ContentOutlinePage {
2 private SashForm sash;//使用 SashForm 把 Outline 视图分为两部分：显示大纲和显示鹰眼
4 private ScrollableThumbnail thumbnail;
5 private DisposeListener disposeListener;
6
7 public EditorContentOutlinePage() {
8 super(new TreeViewer());
9 // 使用GEF的TreeViewer
10 }
11
12 @Override
13 public void init(IPageSite pageSite) {
14 // TODO Auto-generated method stub
15 super.init(pageSite);
16
17 ActionRegistry registry = getActionRegistry();
18 IActionBars bars = pageSite.getActionBars();
19
20 String id = ActionFactory.UNDO.getId();
21 bars.setGlobalActionHandler(id, registry.getAction(id));
22 id = ActionFactory.REDO.getId();
23 bars.setGlobalActionHandler(id, registry.getAction(id));
24 id = ActionFactory.DELETE.getId();
25 bars.setGlobalActionHandler(id, registry.getAction(id));
26 id = ActionFactory.SAVE.getId();
27 bars.setGlobalActionHandler(id, registry.getAction(id));
28 id = ActionFactory.SAVE_ALL.getId();
29 bars.setGlobalActionHandler(id, registry.getAction(id));
30
31 bars.updateActionBars();
32 }
33
34 @Override
35 public void createControl(Composite parent) {
36 // TODO Auto-generated method stub
37
38 sash = new SashForm(parent, SWT.VERTICAL);
39
40 getViewer().createControl(sash);
41
42 getViewer().setEditDomain(getEditDomain());
43 getViewer().setEditPartFactory(new TreePartFactory());
44
45 getViewer().setContents(diagram);
46 getSelectionSynchronizer().addViewer(getViewer());
47
48 Canvas canvas = new Canvas(sash, SWT.BORDER);
49 LightweightSystem lws = new LightweightSystem(canvas);
50
51 thumbnail = new ScrollableThumbnail(
52 (Viewport) ((ScalableRootEditPart) getGraphicalViewer()
53 .getRootEditPart()).getFigure());
54 thumbnail.setSource(((ScalableRootEditPart) getGraphicalViewer()
55 .getRootEditPart())
56 .getLayer(LayerConstants.PRINTABLE_LAYERS));
57
58 lws.setContents(thumbnail);
59
60 disposeListener = new DisposeListener() {
61
62 @Override
63 public void widgetDisposed(DisposeEvent e) {
64 // TODO Auto-generated method stub
65 if (thumbnail != null) {
66 thumbnail.deactivate();
67 thumbnail = null;
68 }
69 }
70
71 };
72
73 getGraphicalViewer().getControl().addDisposeListener(
74 disposeListener);
75 }
76
77 @Override
78 public Control getControl() {
79 // 当大纲视图是当前（active）视图时，返回聚焦的控件。
80 return sash;
81 }
82
83 @Override
84 public void dispose() {
85 // TODO Auto-generated method stub
86 getSelectionSynchronizer().removeViewer(getViewer());
87
88 if (getGraphicalViewer().getControl() != null
89 && !getGraphicalViewer().getControl().isDisposed()) {
90 getGraphicalViewer().getControl().removeDisposeListener(
91 disposeListener);
92
93 }
94 super.dispose();
95 }
96
97 }
（2）在Perspective类中加入大纲视图
public class Perspective implements IPerspectiveFactory {
public void createInitialLayout(IPageLayout layout) {
final String editorArea=layout.getEditorArea();
IFolderLayout leftTopFolder=layout.createFolder("leftTopOutline", IPageLayout.LEFT, 0.35f, editorArea);
leftTopFolder.addView(TTCNView.VIEW_PROJECT);
leftTopFolder.addView(TTCNView.VIEW_EOUTLINE);
IFolderLayout midBottomFolder=layout.createFolder("BottomProperty", IPageLayout.BOTTOM, 0.35f,editorArea );
midBottomFolder.addView(TTCNView.VIEW_DPROPERTY);
midBottomFolder.addView(TTCNView.VIEW_CORELANG);
midBottomFolder.addView(TTCNView.VIEW_TODOITEM);
midBottomFolder.addView(IPageLayout.ID_PROBLEM_VIEW);
layout.addFastView(TTCNView.VIEW_DEFINE);
layout.setEditorAreaVisible(true);
}
}
（3）让大纲视图显示当前GraphicalEditor中的图形信息。
1 public class CustomTreeEditPart extends AbstractTreeEditPart implements
2 PropertyChangeListener {
3
4 @Override
5 public void propertyChange(PropertyChangeEvent arg0) {
6 // TODO Auto-generated method stub
7
8 }
9
10 @Override
11 public void activate() {
12 // TODO Auto-generated method stub
13 super.activate();
14 ((AbstractModel) getModel()).addPropertyChangeListener(this);
15 }
16
17 @Override
18 public void deactivate() {
19 // TODO Auto-generated method stub
20 ((AbstractModel) getModel()).removePropertyChangeListener(this);
21 super.deactivate();
22 }
23
24
25 }
（4）对应于某个类如contentsModel，创建相应的类ContentsTreeEditPart。
1 public class ContainerTreeEditPart extends CustomTreeEditPart {
2
3 @Override
4 public void propertyChange(PropertyChangeEvent arg0) {
5 // TODO Auto-generated method stub
6 if (arg0.getPropertyName().equals(
7 ModelStringConstant.P_CONTAINER_CHILDREN_ADD)) {
8 refreshChildren();
9 } else if (arg0.getPropertyName().equals(
10 ModelStringConstant.P_CONTAINER_CHILDREN_REM)) {
11 refreshChildren();
12 }
13 }
14
15 @Override
16 public List<Object> getModelChildren() {
17 return ((ContainerElementModel) getModel()).getChildren();
18
19 }
20
21 @Override
22 protected void refreshVisuals() {
23 // TODO Auto-generated method stub
24 ContainerElementModel model = (ContainerElementModel) getModel();
25 setWidgetText(model.getLabel());
26 setWidgetImage(TreeEditorPartDescriptorFactory.getContainerImage(model));
27 }
28
29 }
（5）对应于 DiagramModel 类，创建的相应类DiagramTreeEditPart 如下：
1 public class DiagramTreeEditPart extends CustomTreeEditPart {
2
3 @Override
4 public void propertyChange(PropertyChangeEvent arg0) {
5 // TODO Auto-generated method stub
6
7 if (arg0.getPropertyName().equals(
8 ModelStringConstant.P_DIAGRAM_PORTS_INC)) {
9 refreshChildren();
10 } else if (arg0.getPropertyName().equals(
11 ModelStringConstant.P_DIAGRAM_PORTS_DEC)) {
12 refreshChildren();
13 }
14 }
15
16 @Override
17 public List<Object> getModelChildren() {
18 // TODO Auto-generated method stub
19 List<Object> list = ((DiagramModel) getModel()).getChildren();
20 List<Object> children = new ArrayList<Object>();
21 Object model;
22 for (int i = 0; i < list.size(); i++) {
23 model = list.get(i);
24 if (model instanceof PortElementModel) {
25 children.add(model);
26 }
27 }
28
29 return children;
30 }
31
32 }
（6）和图形的绘制一样，我们同样要有一个工厂把这些 Tree Editpart 和相应的模型联系起来。
1 public class TreeEditorPartDescriptorFactory不用继承自EditPartFactory么？ {
2
3
4 public static Image getLiteralImage(AbstractModel model) {
5 if (model instanceof ActionModel) {
6 return IImageKey.getImage(IImageKey.KEY_ACTION);
7 }
8
9 else if (model instanceof ConditionModel) {
10 return IImageKey.getImage(IImageKey.KEY_CONDITION);
11 }
12 else if (model instanceof CreateModel) {
13 return IImageKey.getImage(IImageKey.KEY_CREATE);
14 }
15
16 else if (model instanceof DefaultModel) {
17 return IImageKey.getImage(IImageKey.KEY_DEFAULT);
18 }
19
20 else if (model instanceof EventCommentModel) {
21 return IImageKey.getImage(IImageKey.KEY_EVENTCOMMENT);
22 }
23
24 else if (model instanceof ExecuteModel) {
25 return IImageKey.getImage(IImageKey.KEY_EXECUTE);
26 }
27
28 else if (model instanceof LabelModel) {
29 return IImageKey.getImage(IImageKey.KEY_LABEL);
30 }
31
32 else if (model instanceof GotoModel) {
33 return IImageKey.getImage(IImageKey.KEY_GOTO);
34 }
35
36 else if (model instanceof ReferenceModel) {
37 return IImageKey.getImage(IImageKey.KEY_REFERENCE);
38 }
39
40 else if (model instanceof StartModel) {
41 return IImageKey.getImage(IImageKey.KEY_START);
42 }
43
44 else if (model instanceof TextModel) {
45 return IImageKey.getImage(IImageKey.KEY_TEXT);
46 }
47
48 return null;
49 }
50
51 public static Image getContainerImage(AbstractModel model) {
52 if (model instanceof ContainerElementModel) {
53 return IImageKey.getImage(IImageKey.KEY_INLINE);
54 }
55 return null;
56 }
57
58 public static Image getFigureImage(AbstractModel model) {
59 if (model instanceof StartTimerModel) {
60 return IImageKey.getImage(IImageKey.KEY_STARTTIMER);
61 }
62
63 else if (model instanceof StopComponentModel) {
64 return IImageKey.getImage(IImageKey.KEY_STOP);
65 }
66
67 else if (model instanceof StopTimerModel) {
68 return IImageKey.getImage(IImageKey.KEY_STOPTIMER);
69 }
70
71 else if (model instanceof TimeoutTimerModel) {
72 return IImageKey.getImage(IImageKey.KEY_TIMEOUTTIMER);
73 }
74
75 else if (model instanceof StartImplicitTimerModel) {
76 return IImageKey.getImage(IImageKey.KEY_STARTIMPLICITTIMER);
77 }
78
79 else if (model instanceof TimeoutImplicitTimerModel) {
80 return IImageKey.getImage(IImageKey.KEY_TIMEOUTIMPLICITTIMER);
81 }
82
83 else if (model instanceof StopModel) {
84 return IImageKey.getImage(IImageKey.KEY_STOP);
85 }
86
87 else if (model instanceof ReturnModel) {
88 return IImageKey.getImage(IImageKey.KEY_RETURN);
89 }
90
91 else if (model instanceof RepeatModel) {
92 return IImageKey.getImage(IImageKey.KEY_REPEAT);
93 }
94
95 else if (model instanceof SuspensionRegionModel) {
96 return IImageKey.getImage(IImageKey.KEY_SUSPENSIONREGION);
97 }
98
99 else if (model instanceof InstanceEndModel) {
100 return IImageKey.getImage(IImageKey.KEY_INSTANCEEND);
101 }
102
103
104 return null;
105 }
106
107 public static Image getConnectionImage(AbstractModel model) {
108 String id = ((ElementModel)model).getModelID();
109
110 if (id.equals(ConstantResourceFactory.ID_FOUND_MODEL)
111 || id.equals(ConstantResourceFactory.ID_FOUNDCHECK_MODEL)){
112 return IImageKey.getImage(IImageKey.KEY_FOUND);
113 }
114
115 else if(model instanceof MessageFromModel){
116 return IImageKey.getImage(IImageKey.KEY_MESSAGEFROM);
117 }
118
119 else if(model instanceof MessageToModel){
120 return IImageKey.getImage(IImageKey.KEY_MESSAGETO);
121 }
122 return null;
123 }
124
125 public static Image getPortImage(AbstractModel model) {
126 if (model instanceof PortInstanceModel) {
127 return IImageKey.getImage(IImageKey.KEY_PORT);
128 }
129
130 else if (model instanceof ComponentInstanceModel) {
131 return IImageKey.getImage(IImageKey.KEY_COMPONENT);
132 }
133
134 return null;
135 }
136
137
138 }
而教程中的例子是这样的：
1 public class TreeEditPartFactory implements EditPartFactory {
2 public EditPart createEditPart(EditPart context, Object model) {
3 EditPart part=null;
4 if(model instanceof ContentsModel)
5 part=new ContentsTreeEditPart();
6 else if(model instanceof HelloModel)
7 part=new HelloTreeEditPart();
8 if(part!=null)
9 part.setModel(model);
10 return part;
11 }
12 }
（7）我们再回到 DiagramEditor 中把图形绘制在大纲视图中，过程和绘制图形差不多。
1 class EditorContentOutlinePage extends ContentOutlinePage {
2 private SashForm sash;
3
4 private ScrollableThumbnail thumbnail;
5 private DisposeListener disposeListener;
6
7 public EditorContentOutlinePage() {
8 super(new TreeViewer());
9 // TODO Auto-generated constructor stub
10 }
11
12 @Override
13 public void init(IPageSite pageSite) {
14 // TODO Auto-generated method stub
15 super.init(pageSite);
16
17 ActionRegistry registry = getActionRegistry();
18 IActionBars bars = pageSite.getActionBars();
19
20 String id = ActionFactory.UNDO.getId();
21 bars.setGlobalActionHandler(id, registry.getAction(id));
22 id = ActionFactory.REDO.getId();
23 bars.setGlobalActionHandler(id, registry.getAction(id));
24 id = ActionFactory.DELETE.getId();
25 bars.setGlobalActionHandler(id, registry.getAction(id));
26 id = ActionFactory.SAVE.getId();
27 bars.setGlobalActionHandler(id, registry.getAction(id));
28 id = ActionFactory.SAVE_ALL.getId();
29 bars.setGlobalActionHandler(id, registry.getAction(id));
30
31 bars.updateActionBars();
32 }
33
34 @Override
35 public void createControl(Composite parent) {
36 // TODO Auto-generated method stub
37
38 sash = new SashForm(parent, SWT.VERTICAL);
39
40 getViewer().createControl(sash);
41
42 getViewer().setEditDomain(getEditDomain());
43 getViewer().setEditPartFactory(new TreePartFactory());
44
45 getViewer().setContents(diagram);
46 getSelectionSynchronizer().addViewer(getViewer());
47
48 Canvas canvas = new Canvas(sash, SWT.BORDER);
49 LightweightSystem lws = new LightweightSystem(canvas);
50
51 thumbnail = new ScrollableThumbnail(
52 (Viewport) ((ScalableRootEditPart) getGraphicalViewer()
53 .getRootEditPart()).getFigure());
54 thumbnail.setSource(((ScalableRootEditPart) getGraphicalViewer()
55 .getRootEditPart())
56 .getLayer(LayerConstants.PRINTABLE_LAYERS));
57
58 lws.setContents(thumbnail);
59
60 disposeListener = new DisposeListener() {
61
62 @Override
63 public void widgetDisposed(DisposeEvent e) {
64 // TODO Auto-generated method stub
65 if (thumbnail != null) {
66 thumbnail.deactivate();
67 thumbnail = null;
68 }
69 }
70
71 };
72
73 getGraphicalViewer().getControl().addDisposeListener(
74 disposeListener);
75 }
76
77 @Override
78 public Control getControl() {
79 // TODO Auto-generated method stub
80 return sash;
81 }
