기존에 나왔던 불필요한 항목들이 사라졌습니다.~~

StatusDropDownAction.java
 >> IMenuCreator 를 구현하는게 핵심인 것 같습니다.
public class StatusDropDownAction extends Action implements IMenuCreator, IWorkbenchAction { private Menu fMenu; public StatusDropDownAction() { setText("상태 메뉴"); setToolTipText("메신저상의 상태를 변경합니다."); setImageDescriptor(AbstractUIPlugin.imageDescriptorFromPlugin( Application.PLUGIN_ID, "icons/status.png")); setMenuCreator(this); } public Menu getMenu(Control parent) { if (fMenu != null) { fMenu.dispose(); } fMenu = new Menu(parent); addStatusActionToMenu(fMenu, UserStatus.Online, "온라인"); addStatusActionToMenu(fMenu, UserStatus.Away, "자리비움"); addStatusActionToMenu(fMenu, UserStatus.Busy, "다른 용무 중"); addStatusActionToMenu(fMenu, UserStatus.Phone, "통화 중"); addStatusActionToMenu(fMenu, UserStatus.Meeting, "회의 중"); addStatusActionToMenu(fMenu, UserStatus.Offline, "오프라인으로 표시"); return fMenu; } private void addStatusActionToMenu(Menu parent, String status, String text) { StatusChangeAction action = new StatusChangeAction(status, text); ActionContributionItem item= new ActionContributionItem(action); item.fill(parent, -1); } public Menu getMenu(Menu parent) { // TODO Auto-generated method stub return null; } public void dispose() { if (fMenu != null) fMenu.dispose(); } }

StatusChangeAction.java
  >> 일반적인 Action 과 동일합니다.
public class StatusChangeAction extends Action { public final static String ID = "kr.co.vicki.jateon.actions.statusChange"; private String status; public StatusChangeAction(String status, String text) { this.status = status; setId(ID + "_" + status); setText(text); setToolTipText(text); setImageDescriptor(AbstractUIPlugin.imageDescriptorFromPlugin( Application.PLUGIN_ID, IImageKeys.Util.statusToKey(status))); } @Override public void run() { // TODO run } /** * 생성된 Action 아이디를 반환합니다. * @return */ public String getActionID() { return ID + "_" + status; } }


다른 Action 을 추가하는 것과 같은형식으로 붙여주면 됩니다.
IToolBarManager toolBarManager = getViewSite().getActionBars().getToolBarManager(); IWorkbenchAction statusAction = new StatusDropDownAction(); toolBarManager.add(statusAction);

Application

일반적인 자바프로그앰의 main 메소드를 갖는 클래스와 유사.
프로그램 또는 제품의 진입점(entry point).

Ganymede 에서는 start() 메소드와 stop() 메소드를 구현



WorkbenchAdvisor

워크벤치가 어떻게 행동할지를 말해줌. (그리는 방법, 그릴 대상 등의 정보)
ㅁ 초기에 보여줄 퍼스펙티브 (getInitialWindowPerspectiveId() 메소드)
ㅁ 사용할 WorkbenchWindowAdvisor (createWorkbenchWindowAdvisor() 메소드)



Perspective

템플릿에서는 별 다른 처리를 하지 않음.
일반적인 이클립스의 퍼스펙티브 구성을 의미하는 것으로 추정됨...



WorkbenchWindowAdvisor

Application 내의 모든 윈도우는 WorkbenchWindowAdvisor 에 의해 UI 를 처리.
윈도우의 생명주기 상의 시점에 맞게 적절한 역할을 처리. (preWindowOpen(), postWindowCreate())



ActionBarAdvisor

윈도우가 필요로하는 액션들을 생성하고, 윈도우에 배치.

ㅁ OutlinePage class
  - Outline View 와 Overview 를 inner class로 구성

ㅁ ResourceTracker class
  - 에디터에 열려진 파일이 삭제되거나 변경이 되었음을 감지하여 처리

ㅁ IPartListener listener
  - 열려져 있는 상태에서 저장하지않고 파일이 삭제된 경우 저장할 것인지를 묻는 다이얼로그의 처리

ㅁ configureGraphicalViewer method
  - 루트 에디트파트를 정의
  - 줌 액션을 등록
  - 컨텍스트 메뉴를 등록
  - 키 핸들러를 설정
  - 프로퍼티들을 로드
  - 기타 액션들을 정의 (룰러, 지오메트리, 그리드)

ㅁ createActions method
  - 기본적인 액션들을 등록

ㅁ createGraphicalViewer method
  - 룰러를 사용할 경우 처리

ㅁ setInput method
  - 파일을 읽어들이는 작업??
  - 요건 파악이 아직 잘 안되능~~

ㅁ 저장과 관련된 작업들
  - doSave(), doSaveAs()

추가하는 방법은 너무나 쉽습니다.

ActionBarContributor 에 action 을 등록하고 toolbar 에 추가한 후

GraphicalEditor 에서 액션을 등록하면 완료~~

public class FormWizardEditorActionBarContributor extends ActionBarContributor { ... @Override protected void buildActions() { ... addRetargetAction(new AlignmentRetargetAction(PositionConstants.LEFT)); addRetargetAction(new AlignmentRetargetAction(PositionConstants.CENTER)); addRetargetAction(new AlignmentRetargetAction(PositionConstants.RIGHT)); addRetargetAction(new AlignmentRetargetAction(PositionConstants.TOP)); addRetargetAction(new AlignmentRetargetAction(PositionConstants.MIDDLE)); addRetargetAction(new AlignmentRetargetAction(PositionConstants.BOTTOM)); ... } @Override public void contributeToToolBar(IToolBarManager toolBarManager) { ... toolBarManager.add(new Separator()); toolBarManager.add(getAction(GEFActionConstants.ALIGN_LEFT)); toolBarManager.add(getAction(GEFActionConstants.ALIGN_CENTER)); toolBarManager.add(getAction(GEFActionConstants.ALIGN_RIGHT)); toolBarManager.add(new Separator()); toolBarManager.add(getAction(GEFActionConstants.ALIGN_TOP)); toolBarManager.add(getAction(GEFActionConstants.ALIGN_MIDDLE)); toolBarManager.add(getAction(GEFActionConstants.ALIGN_BOTTOM)); toolBarManager.add(new Separator()); toolBarManager.add(getAction(GEFActionConstants.MATCH_WIDTH)); toolBarManager.add(getAction(GEFActionConstants.MATCH_HEIGHT)); ... } ... }

Model 수정
복사할 대상인 SimpleElement 의 clone() 메소드를 오버라이딩합니다. public 으로다가...
public class SimpleElement extends ElementBase { ... @Override public Object clone() throws CloneNotSupportedException { SimpleElement elem = new SimpleElement(); elem.setBackgroundColor(getBackgroundColor()); elem.setBorder(getBorder()); elem.setFontData(getFontData()); elem.setForegroundColor(getForegroundColor()); elem.setParent(getParent()); elem.setText(getText()); Rectangle rect = getLayout().getCopy(); rect.x += 10; rect.y += 10; elem.setLayout(rect); return elem; } }



Copy Action & Commnd
복사를 위해서 등록할 Action 과 명령을 처리하는 Command가 필요합니다.

붙여넣기에 사용됩니다~



Cut Action and Command
예제에는 없었지만 그냥 한번 만들어 봤습니다. 현재는 부모가 되는 요소가 한개뿐이라 별 필요는 없지만

나중에라도 사용할 수 있게 만들어보았습니다. CopyElemntCommand 를 상속받았습니다. (귀찮아서...)
package kr.co.vicki.formwizard.actions; import java.util.Iterator; import java.util.List; import kr.co.vicki.formwizard.model.ElementBase; import kr.co.vicki.formwizard.model.commands.CutElementCommand; import org.eclipse.gef.EditPart; import org.eclipse.gef.commands.Command; import org.eclipse.gef.ui.actions.SelectionAction; import org.eclipse.ui.ISharedImages; import org.eclipse.ui.IWorkbenchPart; import org.eclipse.ui.PlatformUI; import org.eclipse.ui.actions.ActionFactory; public class CutElementAction extends SelectionAction { public CutElementAction(IWorkbenchPart part) { super(part); setLazyEnablementCalculation(true); } @Override protected void init() { super.init(); ISharedImages sharedImages = PlatformUI.getWorkbench().getSharedImages(); setText("Cut"); setId(ActionFactory.CUT.getId()); setHoverImageDescriptor(sharedImages.getImageDescriptor(ISharedImages.IMG_TOOL_CUT)); setImageDescriptor(sharedImages.getImageDescriptor(ISharedImages.IMG_TOOL_CUT)); setDisabledImageDescriptor(sharedImages.getImageDescriptor(ISharedImages.IMG_TOOL_CUT_DISABLED)); setEnabled(true); } private Command createCutCommand(List<Object> selectedObjects) { if (selectedObjects == null || selectedObjects.isEmpty()) return null; CutElementCommand cmd = new CutElementCommand(); for (Iterator<Object> it=selectedObjects.iterator(); it.hasNext(); ) { EditPart ep = (EditPart) it.next(); ElementBase element = (ElementBase) ep.getModel(); if (!cmd.isCopyableElement(element)) return null; cmd.addElement(element); } return cmd; } @Override protected boolean calculateEnabled() { Command cmd = createCutCommand(getSelectedObjects()); if (cmd == null) return false; return cmd.canExecute(); } @Override public void run() { Command cmd = createCutCommand(getSelectedObjects()); if (cmd != null && cmd.canExecute()) cmd.execute(); } }
package kr.co.vicki.formwizard.model.commands; import java.util.Iterator; import java.util.List; import kr.co.vicki.formwizard.model.ElementBase; import org.eclipse.gef.ui.actions.Clipboard; public class CutElementCommand extends CopyElementCommand { @Override public void execute() { if (!canExecute()) return; List<ElementBase> list = getSelectedList(); for (Iterator<ElementBase> it=list.iterator(); it.hasNext(); ) { ElementBase element = it.next(); if (isCopyableElement(element)) element.getParent().removeChild(element); } Clipboard.getDefault().setContents(list); } @Override public boolean canUndo() { return getSelectedList() != null && !getSelectedList().isEmpty(); } @Override public void undo() { List<ElementBase> list = getSelectedList(); for (Iterator<ElementBase> it=list.iterator(); it.hasNext(); ) { ElementBase element = it.next(); if (isCopyableElement(element)) element.getParent().addChlid(element); } } }


뭐 GEF 하시는 분들이 중급 이상의 자바실력을 가지고 있을거라 생각되기 때문에

다른 소스 설명은 하지 않겠습니다. (절대 귀찮아서가 아닙니다.)


이제 모든 재료들이 준비가 되었으니 적용하는 일만 남았습니다.

Actions 와 Commands 의 적용
public class FormWizardEditorActionBarContributor extends ActionBarContributor { @Override protected void buildActions() { ... IWorkbenchWindow iww = getPage().getWorkbenchWindow(); addRetargetAction((RetargetAction) ActionFactory.COPY.create(iww)); addRetargetAction((RetargetAction) ActionFactory.CUT.create(iww)); addRetargetAction((RetargetAction) ActionFactory.PASTE.create(iww)); } ... @Override public void contributeToToolBar(IToolBarManager toolBarManager) { ... toolBarManager.add(getAction(ActionFactory.COPY.getId())); toolBarManager.add(getAction(ActionFactory.CUT.getId())); toolBarManager.add(getAction(ActionFactory.PASTE.getId())); ... } ... }
에디터에 액션을 등록합니다.
public class FormWizardEditor extends GraphicalEditorWithFlyoutPalette { ... @Override protected void createActions() { super.createActions(); ActionRegistry registry = getActionRegistry(); IAction action = new CopyElementAction(this); registry.registerAction(action); getSelectionActions().add(action.getId()); action = new CutElementAction(this); registry.registerAction(action); getSelectionActions().add(action.getId()); action = new PasteElementAction(this); registry.registerAction(action); getSelectionActions().add(action.getId()); } ... class OutlinePage extends ContentOutlinePage { ... @Override public void createControl(Composite parent) { ... IActionBars bars = getSite().getActionBars(); ActionRegistry ar = getActionRegistry(); bars.setGlobalActionHandler(ActionFactory.COPY.getId(), ar.getAction(ActionFactory.COPY.getId())); bars.setGlobalActionHandler(ActionFactory.PASTE.getId(), ar.getAction(ActionFactory.PASTE.getId())); } ... } }
컨텍스트 메뉴에도 등록해줍니다.
public class FormWizardContextMenuProvider extends ContextMenuProvider { ... @Override public void buildContextMenu(IMenuManager menu) { ... action = getActionRegistry().getAction(ActionFactory.COPY.getId()); menu.appendToGroup(GEFActionConstants.GROUP_COPY, action); action = getActionRegistry().getAction(ActionFactory.CUT.getId()); menu.appendToGroup(GEFActionConstants.GROUP_COPY, action); action = getActionRegistry().getAction(ActionFactory.PASTE.getId()); menu.appendToGroup(GEFActionConstants.GROUP_COPY, action); } ... }
Ctrl + C, Ctrl + V 도 사용해야겠죠?? 처음에는 keyHandler 에 등록하려 애를 써봤지만 다른 방법이 있었습니다. (역시 삽질 ㅋㅋ)
public class ApplicationActionBarAdvisor extends ActionBarAdvisor { ... protected void makeActions(IWorkbenchWindow window) { register(ActionFactory.UNDO.create(window)); register(ActionFactory.REDO.create(window)); register(ActionFactory.COPY.create(window)); register(ActionFactory.CUT.create(window)); register(ActionFactory.PASTE.create(window)); } ... }


이래하면 복사/잘라내기/붙여넣기가 잘 됩니다 ㅋㅋㅋ 안되면... 코멘트 남겨주세요....
