Java新一代GUI[/quote]嗯，比Swing简单使用，但是还是有很多bugs和许多没有公开的api和Css

我就是只能实现这种才来问的。
Stage hide()后，事件就阻塞了。能不能设置Stage让它不这样？

Builder的效率有问题，而且还有很多隐患，参看Oracle给出的文档解释，api 8中已经删除了控件Builder

不过你说的“stage.getEventDispatcher().dispatchEvent（）;事件类型没找到最大化/最小化的事件！”是语法上行不通的，你要派发事件，那么首先要生成你想要的事件，例如：
changeButton.dispatchEvent(new MouseEvent(component, e.getID(), e
.getWhen(), e.getModifiers(), componentPoint.x,
componentPoint.y, e.getClickCount(), e.isPopupTrigger()));fearlessMore 2014-01-03

你看Swing中怎么操作再说吧
