侦听器，用于最小化，最大化等舞台 [英] Listener for a Stage minimizing, maximizing, etc

问题描述

我刚刚开始我的第二个JavaFX项目，我需要知道何时最大化Stage.在Swing中，这非常简单，可以通过使用WindowListener/Event来完成.但是，在搜索了JavaFX的Javadoc之后，我似乎找不到任何监听Stage状态的方法.

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.

有没有办法做到这一点?

Is there any way to do this?

推荐答案

要了解Stage是否已最小化，可以收听iconified属性:

To find out if Stage minimized you can listen to iconified property:

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

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

在即将发布的8.0版本中添加了

通讯员maximized属性:

Correspondent maximized property is added in the upcoming 8.0 release:

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

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