[JavaFX] stage.hide() puis stage.show()
J'ai un problème d'affichage!
J'ai mis mon application JavaFX en mode IconTray avec 3 menu possible (Show, Hide et Close)
- Show devrait afficher mon application
- Hide devrait le masquer
- Close devrait le fermet
Le problème se trouve sur le scénario suivant :
1 - Je clic sur Hide, mon application est vraiment masquée!
2 - Je clic sur Show, rien ne se passe , alors que ma fenètre devrait se réaffichée
Voic mon code

Le problème (je crois) c'est que l'aaplication ne retrouve plus le Thread nommé "FX application Thread" et reste bloqué sur le Thread de java.awt après que je clic sur Hide.
Merci de votre aide!
