Question

我创建了一个包含两个编辑器页面的编辑器。我为属性测试人员添加了两个页面的工具栏项目。在第一页，物业测试人员工作正常。但是，如果我打开编辑器，选择第二页并选择树项，属性测试人员将无法正常工作。手动要求评估财产测试人员不起作用。在第一页上选择另一个视图或树项后，属性测试人员也可以在第二页上正常工作。有什么问题？这是编辑器的一个例子：

public class MyEditor extends FormEditor {

    @Override
    protected void addPages() {
        try {
            addPage(new MyPage(this));
            addPage(new MyPage(this));
        } catch (PartInitException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

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

    @Override
    public void doSave(IProgressMonitor monitor) {
        // nothing to do
    }

    @Override
    public void doSaveAs() {
        // nothing to do
    }

}

class MyPage extends FormPage {

    private static final String TOOLBAR_URI = "toolbar:my.page";

    public MyPage(final FormEditor editor) {
        super(editor, MyPage.class.getName(), "Test");
    }

    @Override
    protected void createFormContent(final IManagedForm managedForm) {

        final ScrolledForm form = managedForm.getForm();

        final ToolBarManager toolbarManager = (ToolBarManager) form.getToolBarManager();
        final IMenuService menuService = (IMenuService) getSite().getService(IMenuService.class);
        menuService.populateContributionManager(toolbarManager, TOOLBAR_URI);

        final Composite body = managedForm.getForm().getBody();
        body.setLayout(new GridLayout());

        final TreeViewer treeViewer = new TreeViewer(body);
        treeViewer.setContentProvider(new MyContentProvider());
        treeViewer.setLabelProvider(new ColumnLabelProvider());
        treeViewer.setInput(Arrays.asList(new String[] { "A", "B", "C" }));

        getSite().setSelectionProvider(treeViewer);
    }

}

class MyContentProvider implements ITreeContentProvider {

    @Override
    public Object[] getElements(final Object inputElement) {
        return ((List<String>) inputElement).toArray();
    }

    @Override
    public Object[] getChildren(final Object parentElement) {
        return new Object[] {};
    }

    @Override
    public Object getParent(final Object element) {
        return null;
    }

    @Override
    public boolean hasChildren(final Object element) {
        return false;
    }

    @Override
    public void dispose() {
        // nothing to do
    }

    @Override
    public void inputChanged(final Viewer viewer, final Object oldInput, final Object newInput) {
        // nothing to do
    }
}

处理程序：

<handler
    class="EditHandler"
    commandId="myEdit">
    <activeWhen>
        <with
            variable="selection">
            <test
                property="my.active">
            </test>
        </with>
    </activeWhen>
</handler>

物业测试员注册：

<propertyTester
    class="MyPropertyTester"
    id="MyPropertyTester"
    namespace="my"
    properties="active"
    type="java.lang.Object">
</propertyTester>

物业测试员：

public class MyPropertyTester extends PropertyTester {

    public static final String ID = MyPropertyTester.class.getName();

    public static final String ACTIVE = "active";

    @Override
    public boolean test(final Object receiver, final String property, final Object[] args, final Object expectedValue) {

        if (receiver instanceof IStructuredSelection) {
            final IStructuredSelection selection = (IStructuredSelection) receiver;
            if (selection.size() == 1) {
                return isMatch(property);
            }
        }
        return false;
    }

    private static boolean isMatch(final String property) {
        if (ACTIVE.equals(property)) {
            return true;
        }
        return false;
    }

}

Answer 1

我＆＃34;修复＆＃34;它通过编辑页面上的黑客改变：

@Override
protected void pageChange(int newPageIndex) {
    List<IWorkbenchPart> views = ... // find all opened IWorkbenchPart
    if (!views.isEmpty()) {
        views.get(0).setFocus();
        this.setFocus();
    }
    super.pageChange(newPageIndex);
}

属性测试器不适用于第二个编辑器页面
