Question

（已解决）我正在使用场景构建器和FXML，我正在努力使其如果用户单击文本字段，它将启用该文本字段进行编辑并禁用另一个文本字段。我似乎无法弄清楚如何制作一个在文本字段中听取鼠标点击的动作事件，而且我看到的所有问题都是FX，而不是FXML。

这是我到目前为止的代码：

@FXML
    public void radiohandleBW(MouseEvent event){
        if(event.getSource() == fullBW){ //I think this line is throwing the error
            if(fullBW.isPressed()){
                System.out.println("pressed");
            }
        }
    }

这是编译器错误：

如果我做错了，请告诉我，我知道这不仅仅是一个简单的修复。
