如何在 RCP-Perspective 中保存编辑器？

Question

在我的 RCP 插件项目中，我有一个视图和一个编辑器。我还设置了一个透视图，其中创建了视图和编辑器。

问题是编辑器的内容（在createPartControl-方法中描述）没有显示。如果我更改 run configurations 并在 Workspace Data 中设置 clear，我将获得默认视角，当我单击 Window -> Perspective -> Open Perspective -> Other... 时，我可以选择我的 "BDD Perspective" 和编辑器及其内容和视图可见。 Perspective with editor and view 如果 Workspace Data 中的 clear 未设置，我的 "BDD Perspective" 会出现，但编辑器为空。 Perspective with empty editor and view

有谁知道如何使编辑器的内容在用户定义的视角中可见？

这是相关代码。在透视图中有一个名为 "CallBDDEditor" 的处理程序，它打开编辑器：

public class Perspective implements IPerspectiveFactory {

String ID = "bddperspective";

@Override
public void createInitialLayout(IPageLayout layout) {

    String editorArea = layout.getEditorArea();

    IFolderLayout right = layout.createFolder("right", IPageLayout.RIGHT, .15f, editorArea);
    right.addView(DiagramView.ID);

    IViewLayout viewLayout = layout.getViewLayout(DiagramView.ID);
    if (viewLayout != null) {
        viewLayout.setCloseable(false);
        viewLayout.setMoveable(false);
    }
    layout.setEditorAreaVisible(true);
    layout.setFixed(true);
    try {
        new CallBDDEditor().execute(null);
    } catch (ExecutionException e) {
        e.printStackTrace();
    }
    IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
    IWorkbenchPage page = window.getActivePage();
    IPerspectiveRegistry perspectiveRegistry = window.getWorkbench().getPerspectiveRegistry();
    IPerspectiveDescriptor personalPerspectiveDescriptor = perspectiveRegistry.findPerspectiveWithId(ID);

    if (page != null && personalPerspectiveDescriptor != null) {
        page.savePerspectiveAs(personalPerspectiveDescriptor);
    }
}}

public class CallBDDEditor extends AbstractHandler {

public static final String ID = "bdd.klighd.openBDDEditor";

@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
    IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
    IWorkbenchPage page = window.getActivePage();
    try {
        page.openEditor(new BDDEditorInput("test of editor input"), BDDEditor.ID);
    } catch (PartInitException e) {
        e.printStackTrace();
    }
    return null;
}

@Override
public boolean isEnabled() {
    return false;
}

@Override
public boolean isHandled() {
    return false;
}

@Override
public void removeHandlerListener(IHandlerListener handlerListener) {
}}

public class BDDEditor extends EditorPart {

public static final String ID = "bdd.klighd.BDDEditor";
boolean dirty = false;
private String formula_ = "f(x,y,z) = x!y + z!x";

ToolItem inputItem_;
ToolItem showItem_;
ToolItem simplifyItem_;
ToolItem removeItem_;
ToolItem cancelItem_;
Composite parent_;
ToolBar bar_;
private Label formulaLbl_;

@Override
public void init(IEditorSite site, IEditorInput input) throws PartInitException {
    super.setSite(site);
    super.setInput(input);
}

@Override
public boolean isDirty() {
    return false;
}

@Override
public void createPartControl(Composite parent) {
    parent_ = parent;
    GridLayout layout = new GridLayout();
    layout.numColumns = 1;
    parent_.setLayout(layout);
    formulaLbl_ = new Label(parent_, SWT.NONE);
    formulaLbl_.setText("");
    bar_ = new ToolBar(parent_, SWT.BORDER | SWT.VERTICAL);

    // create items
    inputItem_ = new ToolItem(bar_, 0);
    showItem_ = new ToolItem(bar_, SWT.PUSH);
    simplifyItem_ = new ToolItem(bar_, SWT.PUSH);
    removeItem_ = new ToolItem(bar_, SWT.PUSH);
    cancelItem_ = new ToolItem(bar_, 0);

    // set text on items
    inputItem_.setText("INPUT");
    showItem_.setText("SHOW");
    simplifyItem_.setText("SIMPLIFY");
    removeItem_.setText("REMOVE");
    cancelItem_.setText("CANCEL");

    // disable show-, simplify-, remove- and cancelItems
    showItem_.setEnabled(false);
    simplifyItem_.setEnabled(false);
    removeItem_.setEnabled(false);
    cancelItem_.setEnabled(false);

    DropdownSelectionListener listenerInput = new DropdownSelectionListener(inputItem_);
    listenerInput.add("As String", true);
    listenerInput.add("From File", false);
    inputItem_.addSelectionListener(listenerInput);

    bar_.pack();
    parent_.pack();
}

public IEditorInput getEditorInput() {
    return super.getEditorInput();
}

@Override
public void doSave(IProgressMonitor monitor) {
}

@Override
public boolean isSaveAsAllowed() {
    return true;
}

@Override
public void setFocus() {
}

@Override
public void dispose() {
    super.dispose();
}

@Override
public void doSaveAs() {
}}

我已经在 Extensions ElementFactory 中添加了，就像您在此处看到的那样 ElementFactory。这是我的 ElementFactory 代码：

public class ElementFactory implements IElementFactory, IAdaptable {

String ID = "bdd.klighd.factory";

@Override
public IAdaptable createElement(IMemento memento) {
    return new BDDEditorInput("test of editor input");
}

@Override
public <T> T getAdapter(Class<T> adapter) {
    // TODO Auto-generated method stub
    return null;
}

}

这是我的 EditorInput 代码：

public class BDDEditorInput implements IStorageEditorInput, IPersistableElement {

private final String inputString;

public BDDEditorInput(String inputString) {
    this.inputString = inputString;
}

public boolean exists() {
    return true;
}

public ImageDescriptor getImageDescriptor() {
    return null;
}


@Override
public void saveState(IMemento memento) {
    // TODO Auto-generated method stub

}

@Override
public String getFactoryId() {
    return "bdd.klighd.factory";
}

public IPersistableElement getPersistable() {
    return this;
}

public IStorage getStorage() throws CoreException {
    return new IStorage() {
        public InputStream getContents() throws CoreException {
            return new StringBufferInputStream(inputString);
        }

        public IPath getFullPath() {
            return null;
        }

        public String getName() {
            return BDDEditorInput.this.getName();
        }

        public boolean isReadOnly() {
            return false;
        }

        public Object getAdapter(Class adapter) {
            return null;
        }
    };
}

public Object getAdapter(Class adapter) {
    return null;
}

public String getName() {
    return "input name";
}

public String getToolTipText() {
    return "BDD Editor";
}

}

是的，它有效，我的 items/buttons 现在可见了。但是不知道为什么，因为我没有在EditorInput-class中实现它们。但是，它有效！
