In JavaFX, how to open another stage without losing focus of the first one?

Question

I have a main stage that must open another stage without losing focus of the first one. I know i can call mainWindow.requestFocus() after calling secondWindow.show() but i want to make it to work without the first window even losing focus.

I wanto to do this because the second stage is a notification window with StageStyle.TRANSPARENT, that stays always on top and closes itself after some seconds. Is there a way to make the second window "unfocusable"?

Answer 1

Do you really need to create a new Stage for showing your notification window? You could also use javafx.stage.Popup which creates transparent windows by default (so you would not need to set StageStyle.TRANSPARENT). Another advantage of using Popup instead of Stage is that it doesn't "steal" the focus from your main stage, wich should be pretty much what you need.

Here is some more information about the popup class: https://docs.oracle.com/javase/8/javafx/api/javafx/stage/Popup.html

And here is a simple example of how to use a popup in your application: https://gist.github.com/jewelsea/1926196
