  在编码是仅仅需要编写Handler中的代码：

 

 

package com.vnvntrip.plugin.dev.handlers;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.handlers.HandlerUtil;
import org.eclipse.ui.internal.dialogs.WorkbenchPreferenceDialog;

/**
 * 
 * @author longgangbai
 *
 */
public class SampleHandler extends AbstractHandler {
    private static String CUSTOMPROPERTYPAGE = "com.vnvntrip.plugin.dev.properties.CustomPropertyPage";

    /**
     * The constructor.
     */
    public SampleHandler() {
    }

    /**
     * the command has been executed, so extract extract the needed information
     * from the application context.
     */
    public Object execute(ExecutionEvent event) throws ExecutionException {
	Shell shell = HandlerUtil.getActiveShell(event);
	// JfaceDialog dialog=new JfaceDialog(shell);
	// dialog.open();
	//WorkbenchPreferenceDialog.createDialogOn(shell, preferencePageId)
	WorkbenchPreferenceDialog dialog = WorkbenchPreferenceDialog
		.createDialogOn(shell, CUSTOMPROPERTYPAGE);
	dialog.showOnly(new String[] { CUSTOMPROPERTYPAGE });
	dialog.open();
	return null;
    }
}
