Eclipse RCP编辑器关闭按钮的障蔽方法

Eclipse RCP编辑器关闭按钮的障蔽方法 Eclipse RCP编辑器关闭按钮的屏蔽方法 首先，在ApplicationWorkbenchWindowAdvisor类的preWindowOpen()方法中注册我们自己 定制的PresentationFactory。 configurer.setPresentationFactory(new UnCloseableEditorPresentationFactory()); UnCloseableEditorPresentationFactory类继承WorkbenchPresentationFactory类，为了 不影响别的GUI功能，我们只需要重写public StackPresentation createEditorPresentation(Composite parent, IStackPresentationSite site)方法中的关 于设置TableFolder的部分，具体如下: package AdminLoader; import org.eclipse.jface.preference.IPreferenceStore; import org.eclipse.swt.SWT; import org.eclipse.swt.events.DisposeEvent; import org.eclipse.swt.events.DisposeListener; import org.eclipse.swt.widgets.Composite; import org.eclipse.ui.IWorkbenchPreferenceConstants; import org.eclipse.ui.PlatformUI; import org.eclipse.ui.internal.Workbench; import org.eclipse.ui.internal.WorkbenchPlugin; import org.eclipse.ui.internal.presentations.defaultpresentation.DefaultMultiTabListener; import org.eclipse.ui.internal.presentations.defaultpresentation.DefaultTabFolder; import org.eclipse.ui.internal.presentations.defaultpresentation.DefaultThemeListener; import org.eclipse.ui.internal.presentations.defaultpresentation.EmptyTabFolder; import org.eclipse.ui.internal.presentations.util.PresentablePartFolder; import org.eclipse.ui.internal.presentations.util.StandardEditorSystemMenu; import org.eclipse.ui.internal.presentations.util.StandardViewSystemMenu; import org.eclipse.ui.internal.presentations.util.TabbedStackPresentation; import org.eclipse.ui.presentations.IStackPresentationSite; import org.eclipse.ui.presentations.StackPresentation; import org.eclipse.ui.presentations.WorkbenchPresentationFactory; public class UnCloseableEditorPresentationFactory extends WorkbenchPresentationFactory { // don't reset these dynamically, so just keep the information static. // see bug: // 75422 [Presentations] Switching presentation to R21 switches immediately, // but only partially private static int editorTabPosition = WorkbenchPlugin.getDefault() .getPreferenceStore() .getInt(IWorkbenchPreferenceConstants.EDITOR_TAB_POSITION); private static int viewTabPosition = WorkbenchPlugin.getDefault() .getPreferenceStore() .getInt(IWorkbenchPreferenceConstants.VIEW_TAB_POSITION); /* * (non-Javadoc) * * @see org.eclipse.ui.presentations.AbstractPresentationFactory# * createEditorPresentation(org.eclipse.swt.widgets.Composite, * org.eclipse.ui.presentations.IStackPresentationSite) */ public StackPresentation createEditorPresentation(Composite parent, IStackPresentationSite site) { // DefaultTabFolder folder = new DefaultTabFolder(parent, // editorTabPosition | SWT.BORDER, // site.supportsState(IStackPresentationSite.STATE_MINIMIZED), // site.supportsState(IStackPresentationSite.STATE_MAXIMIZED)); DefaultTabFolder folder = new UnCloseableEditorFolder(parent,editorTabPosition | SWT.BORDER, site.supportsState(IStackPresentationSite.STATE_MINIMIZED), site.supportsState(IStackPresentationSite.STATE_MAXIMIZED)); /* * Set the minimum characters to display, if the preference is something * other than the default.
