如果在Mac OS上完全屏蔽，JavaFX警报#showAndWait将永久挂起

（tl；接近底部的dr标记）

上下文 我在一个典型的全屏（POS风格）JFX应用程序中使用JavaFX警报来显示swing内容窗格，以便在阻止窗口中用定制的触摸优化输入提示用户。

我希望警报是全屏的，以符合pos风格。在Mac电脑上，全屏窗口在自己的“空间”中打开；类似于新的桌面空间，但仅适用于一个应用程序

我使用的是运行MacOS10.12的黑客软件。这个问题似乎与Macintosh全屏空间非常相关

值得注意的是，复制需要系统首选项>停靠>首选选项卡…=手册这导致Mac OS将警报作为单独的弹出窗口打开，而不是作为同一应用程序阶段窗口中的选项卡打开。（或者你可以拖出标签页，手动全屏显示，请随意。）我这样做是因为在标签页中呈现swing内容时，警报效果不佳

主场景窗口的全屏状态不影响行为，只影响警报状态

SDK:JDK13.0.4、JavaFX11.0.2

showAndWait（） 正在使用

Alert.showAndWait（）

显示警报，其中

显示对话框并等待用户响应（换句话说，是 打开一个阻塞对话框，返回用户输入的值）。
。。。
方法必须在JavaFX应用程序线程上调用
。。。
必须被称为。。。从传递给的Runnable的run方法 Platform.runLater

正如您在下面看到的，最后一个要求得到了满足。我还检查了以确保它在JFX应用程序线程上被调用

预期 show和wait（）；挂起，直到用户单击警报窗口上的“确定”。之后，窗口关闭，自定义对话框返回从用户收集的值。焦点将返回到JFX应用程序阶段窗口

实际的 实际实现：
如果是窗口，则返回并按预期关闭，焦点返回到包含应用程序场景窗口的空间。如果全屏显示，Mac全屏空间立即消失，没有动画，返回桌面，似乎表明警报窗口突然不再存在，就好像它已经关闭一样，但内容仍然呈现在桌面空间的所有其他内容上。应用程序线程挂起。UI挂起。老鼠沙滩球

简化测试版本：
如果窗口按预期关闭。如果全屏显示，则返回到窗口，停止渲染但保持打开状态。应用程序线程没有停止，但应用程序仍然没有响应（不是“没有响应”，是在海滩上打球，是停止了，只是对任何交互一无所知。）

闲逛 ，我无法复制，但它只是进一步表明这与玻璃窗有关，导致我猜测这是quantum工具包的问题，或者Mac玻璃窗在试图关闭时在空间之间移动（并重新渲染？）

太长了，读不下去了 不知何故，警报关闭导致的全屏空间切换会中断警报的用户确认事件，该事件将释放线程，导致应用程序线程永远停留在showAndWait（）中。我认为整个程序在确认后挂起的原因与警报UI不再可用有关；JavaFX现在正试图将控制权返回到挂起的应用程序线程

可以理解的是，警报窗口可能没有以这种方式进行测试；一个全屏弹出式输入窗口，包含所有Mac的全屏空间

我可能只需要研究另一个选项，或者不用全屏就足够了
