在scenebuilder 2.0中找不到控制器

Question

只是想知道是否可以得到一些帮助，因为我目前正在使用 SceneBuilder 2.0 为我的软件构建 GUI。我遇到了一个问题，我无法将 FXML 文件与控制器链接，即使它们当前位于项目 Screenshot within Eclipse 的同一文件夹中。

对此问题的任何帮助将不胜感激。

谢谢！

编辑：请按要求在 Java Controller 类下方找到：

package rucmView;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.MenuItem;

public class GherkinController {

    @FXML
    private MenuItem exit;

    @FXML
    void ExitApplication(ActionEvent event) {

    }

}

也请按要求查找 FXML 类：

<?import javafx.scene.control.Menu?>
<?import javafx.scene.control.MenuBar?>
<?import javafx.scene.control.MenuItem?>
<?import javafx.scene.control.SplitPane?>
<?import javafx.scene.control.TextArea?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>

Answer 1

你的控制器类和你的 fxml 文件应该在同一个包中。然后您可以在 SceneBuilder 中找到控制器类的选项。或者您可以在 fxml 文件中手动添加，例如：fx:controller="app.fxml.PropertiesDemoController"

前：

<AnchorPane prefHeight="300.0" prefWidth="300.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="app.fxml.PropertiesDemoController">

Answer 2

• 确保控制器是public。
• fx:controller 需要控制器类的完整包路径。
