        Images images = new Images(new Image("http://goo.gl/YsuGV"), Color.TRANSPARENT, StageStyle.TRANSPARENT, 300, 250);
        images.start(garfieldStage);

    }
    if(areaText.contains("@garfieldOff@") || areaText.contains("@garfieldNull@")) {
        garField = false;
        garfieldStage.close();
        System.out.println("Closed");
    }
}

@FXML
protected void onThirdButton() {
    text.setText("More coming soon");
    if(!isClicked) {
        isClicked = true;
        return;
    }
    if(isClicked) {
        isClicked = false;
        text.setText(null);
        return;
    }
}
@FXML
protected void onMenuItem() {
    Dialogs.create().title("Info").message("You can type @color@ to change the color of buttons or you can use @normal@ to change everything back. And there are secret commands :). You use them by doing this @command@").showInformation();
}
}

我正在使用这个atm。但我有这个问题

if(areaText.contains("@:)@") && !garField || areaText.contains("@garfield@") && !garField) {
        Images images = new Images(new Image("http://goo.gl/YsuGV"), Color.TRANSPARENT, StageStyle.TRANSPARENT, 300, 250);
        images.start(garfieldStage);
        garField = true;
    }
    if(areaText.contains("@garfieldOff@") || areaText.contains("@garfieldNull@")) {
        garField = false;
        garfieldStage.close();
        System.out.println("Closed");
    }

它没有关闭，但它确实打印出来，所以.close（）会被调用。

当我将garfieldStage置于方法之外并将其设为私有或公共或受保护或没有修饰符时，当我尝试重新启动时，它会给我这个错误

但它确实关闭了。

Answer 1

创建舞台并在initialize()方法中初始化其样式，然后只引用处理程序方法中的现有（和初始化）阶段：

公共类GamblingClientController {

private Stage garfieldStage ;

// ...

public void initialize() {
    garfieldStage = new Stage();
    garfieldStage.initStyle(...);
}

// ...

}

然后，在您尝试时，从处理程序方法中删除Stage garfieldStage = new Stage();，以及从Stage.initStyle(...)删除Images.start()来电。如果您在舞台上调用任何其他init...(...)方法，请将其移至控制器的initialize()方法。
