java - Listener for a Stage minimizing, maximizing, etc

Question

I am just starting my second JavaFX projects, and I need to know when a Stage is being maximized. In Swing, this is fairly simple and can be accomplished by using a WindowListener/Event. However, after searching through JavaFX's Javadoc, I can't seem to find any way of listening to the state of a Stage.

Is there any way to do this?

要了解是否Stage已最小化，您可以收听iconified属性：

stage.iconifiedProperty().addListener(new ChangeListener<Boolean>() {

    @Override
    public void changed(ObservableValue<? extends Boolean> ov, Boolean t, Boolean t1) {
        System.out.println("minimized:" + t1.booleanValue());
    }
});

maximized在即将发布的 8.0 版本中添加了Correspondent属性：

stage.maximizedProperty().addListener(new ChangeListener<Boolean>() {

    @Override
    public void changed(ObservableValue<? extends Boolean> ov, Boolean t, Boolean t1) {
        System.out.println("maximized:" + t1.booleanValue());
    }
});
