我是靠谱客的博主斯文电话，最近开发中收集的这篇文章主要介绍SWT(JFace) Wizard(Eclipse插件编程必备)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

演示代码如下：

HotelReservation.java

复制代码代码如下:

button.setText("Make a reservation"); 
button.addListener(SWT.Selection, new Listener() { 
public void handleEvent(Event event) { 
ReservationWizard wizard = new ReservationWizard(); 

WizardDialog dialog = new WizardDialog(getShell(), wizard); 
dialog.setBlockOnOpen(true); 
int returnCode = dialog.open(); 
if(returnCode == Dialog.OK) 
System.out.println(wizard.data); 
else 
System.out.println("Cancelled"); 
} 
}); 
return button; 
}
