在 scenebuilder 2.0 中找不到控制器

Question

只是想知道我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。但是我遇到了一个问题，我无法 link FXML file with the Controller even though they are currently within the same folder in the project Screenshot within Eclipse.

非常感谢对此问题的任何帮助。

谢谢！

编辑：请根据要求在 Java 控制器 class 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) {

    }

}

还请按要求查找 FXML class：

<?import javafx.scene.control.Button?>
<?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

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

Answer 2

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

EX:

<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">
