本文介绍了一个自定义的 Eclipse Java 类型选择对话框的实现方式，该对话框用于从工作集或项目中搜索并打开特定类型的 Java 类。通过创建 `OpenTypeDialog` 类并继承 `OpenTypeSelectionDialog`，文章展示了如何设置对话框的标题、消息及过滤器，并演示了如何调用此类来获取用户选择的 Java 类。

import org.eclipse.jdt.internal.ui.JavaPlugin;
import org.eclipse.jdt.internal.ui.JavaUIMessages;
import org.eclipse.jdt.internal.ui.dialogs.OpenTypeSelectionDialog;
import org.eclipse.jdt.internal.ui.search.JavaSearchScopeFactory;
import org.eclipse.ui.IWorkingSet;
import org.eclipse.ui.PlatformUI;

public class OpenTypeDialog extends OpenTypeSelectionDialog {

	public OpenTypeDialog(IWorkingSet ws) {
		super(JavaPlugin.getActiveWorkbenchShell(), true, PlatformUI.getWorkbench().getProgressService(), JavaSearchScopeFactory.getInstance().createJavaSearchScope(ws, true), 0);
		setTitle(JavaUIMessages.OpenTypeAction_dialogTitle);
		setMessage(JavaUIMessages.OpenTypeAction_dialogMessage);
		applyFilter();
	}

	public OpenTypeDialog(IWorkingSet ws, String searchText) {
		this(ws);
		setInitialPattern(searchText);
	}
}

然后调用OpenTypeDialog：

IProject[] projects = new IProject[] { project };
				IAdaptable[] elements = new IAdaptable[projects.length];
				for (int i = 0; i < elements.length; i++) {
					elements[i] = projects[i];
				}
				IWorkingSet ws = new WorkingSet("source", "source", elements);
				SelectionDialog dialog = new OpenTypeDialog(ws);
				int result = dialog.open();
				if (result != IDialogConstants.OK_ID)
					return;

				Object[] obj = dialog.getResult();
				if (obj == null || obj.length == 0)
					return;
				String className = null;
				String packageName = null;
				for (Object objs : obj) {
					className = ((SourceType) objs).getElementName();
					PackageFragment packet = (PackageFragment) ((SourceType) objs).getParent().getParent();
					packageName = packet.getElementName();
				}
