JavaFX - 最小化舞台的按钮

Question

I have an undecorated stage in a JavaFX Application. In order to minimize it I need a minimize button. I created my layout in an fxml document which has a minimize button , but when I try to minimize using the action listener for this button located inside the controller using stage.setIconified(true) , it cannot find stage.

How can I find a reference to the stage in the controller class?

Answer 1

You can try :

button.setOnAction(e -> {
    ((Stage)((Button)e.getSource()).getScene().getWindow()).setIconified(true);
});

Answer 2

Solution number 1 is what ItachiUchiha posted.

Solution number 2 is just creating a setter-method in the controller and give the controller the stage itself.

Answer 3

Use this Stage stage = (Stage) minimize.getScene().getWindow(); stage.setIconified(true); // minimize can be any element in that scene Stage stage = (Stage) minimize.getScene().getWindow(); stage.setIconified(true); // minimize can be any element in that scene
