界面按钮和其他功能无法正常工作

时间：2014-08-25 16:15:25

标签： button interface javafx-8

我正在使用javaFX场景构建器，我创建了一个界面并在其上放置按钮，但是当我按下一个按钮时，它有一个方法可以打印＆＃34; Hello＆＃34;例如，在我第一次按它之后，它什么也没做，在第二次按下之后它按方法执行2次（它打印Hello 2次），之后它工作得很好，但这发生在我的界面上的一切，我必须按下所有按钮2次，我必须将东西悬停2次以便它可以工作，我不知道为什么，能不能帮助我吗？

这是我的FXML

按下bFwd后，蓝点移动2倍于输出所示的距离，其原始（x）坐标为484（起始x坐标），从1点击进入519.5然后到555.0它应该在第二次点击后转到555.0然后它正常（在x坐标上点击35.5单位）抱歉我不能发布图像我有5个代表，需要10个声誉。

1 个答案:

答案 0 :(得分：0)

您描述的问题是由您的处理程序方法引起的。 FXMLLoader的工作方式是它在控件上注册一个处理程序，它调用你指定的方法。

所以

<Button fx:id="bBack" ... onMouseClicked="#setDateBack" ... />

导致FXMLLoader使用调用bBack方法的setDateBack(...)注册处理程序（对于鼠标单击事件）。这样做的结果是当您在bBack按钮上单击鼠标时，将调用setDateBack(...)方法。

但是你对该方法的实现并没有直接执行你想要执行的代码：它只是在按钮上设置另一个处理程序。因此，当您第一次单击按钮上的鼠标时，您的方法会在按钮上设置处理程序。第二次单击该按钮时，将调用第二个处理程序来执行其中的代码。 （由于您使用了setOnMouseClicked(...)方法，因此第二个处理程序将替换第一个。）

你只想要

public void setDateBack(MouseEvent event) {

    if (data.getValue() == null) {
        System.out.println("Introduceti data!!!");
    }

    if (data.getValue().equals(LocalDate.of(2014, 8, 15))) {

        ld = data.getValue();

        System.out.println("" + ld);
        sDate.setText(ld.toString());

        System.out.println("" + ora.getValue());
        labelOra.setText(listaOra.get(0).toString());

        rewindSky(Sirius, -35.5, -4.5);
        rewindSky(Procyon, -35.5, -4.5);
        rewindSky(Beetlegeuse, -35.5, -4.5);
        rewindSky(Polux, -35.5, -4.5);
        rewindSky(Capella, -35.5, -4.5);
        rewindSky(Regulus, -35.5, -4.5);
        rewindSky(Rigel, -35.5, -4.5);
        rewindSky(Aldebaran, -35.5, -4.5);
        rewindSky(Castor, -35.5, -4.5);
        rewindSky(Mirphak, -35.5, -4.5);

        System.out.println("" + Sirius.getLayoutX());
        System.out.println("" + Sirius.getLayoutY());
    }
}

就像说明一样，代码中还有许多其他错误（大部分FXML定义的控件都没有注释，有些控件是reinitialized in your controller，你在按钮上使用鼠标监听器而不是处理动作事件：可能有其他人）。我刚刚解决了你问过的问题。最好是创建minimal example以便隔离每个错误。 （另外，请发布可执行文件示例。没有人可以运行您的代码，因为您引用了所有这些图像，并且图像与问题无关。）
