ブロードキャスト的にセレクションさせる方法

インタフェース　ISetSelectionTarget　を使う

package org.eclipse.ui.part;
import org.eclipse.jface.viewers.ISelection;
public interface ISetSelectionTarget {
    public void selectReveal(ISelection selection);
}

例えば、org.eclipse.ui.wizards.newresource.BasicNewResourceWizard では
こんな感じで使われている

public static void selectAndReveal(IResource resource,
            IWorkbenchWindow window) {
・・・
        IWorkbenchPage page = window.getActivePage();
        List parts = new ArrayList();
        IWorkbenchPartReference refs[] = page.getViewReferences();
        for (int i = 0; i < refs.length; i++) {
            IWorkbenchPart part = refs[i].getPart(false);
            if (part != null) {
				parts.add(part);
			}
        }
        refs = page.getEditorReferences();
        for (int i = 0; i < refs.length; i++) {
            if (refs[i].getPart(false) != null) {
				parts.add(refs[i].getPart(false));
			}
        }
        final ISelection selection = new StructuredSelection(resource);
        Iterator itr = parts.iterator();
        while (itr.hasNext()) {
            IWorkbenchPart part = (IWorkbenchPart) itr.next();
            ISetSelectionTarget target = null;
            if (part instanceof ISetSelectionTarget) {
				target = (ISetSelectionTarget) part;
			} else {
				target = (ISetSelectionTarget) part
                        .getAdapter(ISetSelectionTarget.class);
			}
            if (target != null) {
                // select and reveal resource
                final ISetSelectionTarget finalTarget = target;
                window.getShell().getDisplay().asyncExec(new Runnable() {
                    public void run() {
                        finalTarget.selectReveal(selection);
                    }
                });
            }
        }
    }

ちなみに、ISetSelectionTarget を実装しているクラスは

CommonNavigator , ( ProjectExplorer ) , PackageExplorerPart

ぐらい。
