问题描述
我当时想通过投影来美化未经修饰的JavaFX阶段.我知道如何使用StageStyle.TRANSPARENT做到这一点，但是我注意到，一旦将此标志传递给舞台，我的应用程序的性能就会下降大约10倍.
I was thinking of glorifying my undecorated JavaFX stage with a drop shadow. I know how to do this with StageStyle.TRANSPARENT, but I noticed that as soon as I pass this flag to the Stage, the performance of my app drops approximately by 10x.
任何人都知道可能导致这种巨大性能下降的原因是什么?还有其他方法可以将阴影添加到未装饰的舞台吗?也许分两个阶段进行破解会带来更好的性能?
Anyone have ideas what might cause this enormous performance drop? Is there any other way to add a drop shadow to an undecorated Stage? Perhaps hacking away with two stages would yield better performance?
好的，我正在分两个阶段进行尝试..现在，性能问题已完全消失，在复杂的主要阶段后面有一个虚拟的影子阶段".
OK, I'm trying this with two stages.. the performance problems are completely gone now, with a dummy "shadow stage" behind the complex main stage.
我现在只有两个问题:1.如何使阴影阶段不出现在任务栏中? 2.如何使Shadow Stage鼠标透明?
I have just two questions now, 1. How can I make the shadow stage not appear in the taskbar? 2. How can I make the shadow stage mouse transparent?
同样，不幸的是，如果没有JNI，我要实现的目标将是不可能的.遗憾的是，透明的舞台出于某种原因而吞噬了所有表演.
Appararently, and unfortunately, what I'm trying to achieve isn't possible without JNI. What a pity that a transparent Stage eats all performance for some reason.
推荐答案
当前无法使用标准JavaFX工具包通过StageStyle.TRANSPARENT来提高舞台的性能.
There is currently no way to improve the performance of stages with StageStyle.TRANSPARENT using the standard JavaFX toolkit.
请参阅相关的问题跟踪参考:
See related issue tracker reference:
该问题目前尚无计划实施，尽管我认为可以考虑将其包含在一些不确定的未来版本中.
The issue is currently not planned for implementation, though I guess it could be considered for inclusion in some undetermined future release.
有趣的是，对于我创建的小部件项目而言，性能一直很好，但我从未注意到有问题，但是我想某些应用程序存在问题，否则JavaFX问题跟踪器中不会存在未解决的问题
Anecdotally, the performance has been fine for little widget projects I have created and I have never noticed an issue, but I guess there is an issue there with some applications otherwise there wouldn't be an open issue in the JavaFX issue tracker around it.
