本文介绍了JavaFX 对背景的影响的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用 ，而不是aero.
这可能很重要:我使用的是 Undecorator 的修改版本.>

I'm using this to make a iOS-themed JavaFX2 (Java7) application with a frosted glass effect. The problem is that this code uses its effect on an ImageView. I'd like it to use its effect on whatever's behind the window, like this:
Is there anyway to do that? I'd also like that small drop-shadow effect you see around the above image.
To be clear, I don't want that slider or anything, just the effect of being able to see through the window and having that slight shadow around the edges. I want to use this iOS7-ish effect instead of aero, though.
This might be important: I'm using a modified version of Undecorator.
