JavaFX、SceneBuilder、MenuItem --> 图片

Question

我最近发现了 google-material-图标，现在我想使用图标使我的应用程序更美观。现在我想将图像添加到应用程序关闭 MenuItem。使用 SceneBuilder 你可以只添加项目，但我现在想做的是至少仍然使用 fxml。我有两个问题：

我可以编辑 fxml 而不会再次被 scenebuilder 覆盖吗？
如何将图标添加到 MenuItems？

非常感谢。如果你需要它，这里是我的 FXML：

Answer 1

是的，您可以在 MenuItem 中添加 Image 而不会影响 fxml。

First, add FX:ID to your menu-item.

<MenuItem fx:id="close_item" mnemonicParsing="false" onAction="#handleFileClose" text="Close" />

Now use setGraphic() method to add an ImageView in your menu-item.

@FXML MenuItem close_item;

@Override
public void initialize(URL url, ResourceBundle rb) {

    ImageView menuIcon = new ImageView(new Image("/path/image.png"));
    menuIcon.setFitHeight(20);
    menuIcon.setFitWidth(20);
    close_item.setGraphic(menuIcon);
    //...
    //...
}
