JavaFX 8 How to set program icon to alert?

Question

How can I set program icon to alert without using alert.initOwner()? Why without initOwner? It\'s because some alert must be shown before whole win

Answer 1

The correct implementation is following comments above:

// Get the Stage.
Stage stage = (Stage) alert.getDialogPane().getScene().getWindow();

// Add a custom icon.
stage.getIcons().add(new Image(getClass().getResourceAsStream("images/logo_full3.png")));
