英文:
JavaFX: stage.setOnCloseRequest() not working
问题
我有一个主窗口，在其上打开一个错误对话框。此时，在主窗口和错误对话框（主窗口舞台的一部分）之间显示了一个覆盖层。<br/>
`mainWindowOverlay.setManaged(true)`
当错误对话框关闭时，覆盖层应该消失。<br/>
`errorStage.setOnCloseRequest(we -> overlayOff())`
我不知道是否注册了关闭事件，或者是否还有其他问题，但是错误对话框关闭后，覆盖层仍然保留。
有什么想法？

英文:
I have a main window on top of which an error dialog opens. At that point an overlay is displayed between the main window and the error dialog (part of the main window stage).<br/>
mainWindowOverlay.setManaged(true)
When the error dialog is closed, the overlay should disappear.<br/>
errorStage.setOnCloseRequest(we -> overlayOff())
I don't know if the close event isn' t registered or if there's another problem but the overlay stays after the error dialog has been closed.
Any ideas?
