将自定义组件添加到SceneBuilder 2.0

问题描述

我需要在窗格上有一个选择侦听器和select方法，以便在单击节点时能够监视并显示突出显示。

I have the need to have a selection listener and select method on a pane to be able to monitor and present a highlight when a node is clicked on.

I执行以下操作：

public class PaneWithSelectionListener extends Pane {

    private ObjectProperty<Annotation> selectedAnnotation = new SimpleObjectProperty<>();

    public PaneWithSelectionListener() {
        super();
        selectedAnnotation.addListener((obs, oldAnno, newAnno) -> {
            if (oldAnno != null) {
                oldAnno.setStyle("");
            }
            if (newAnno != null) {
                newAnno.setStyle("-fx-border-color: blue;-fx-border-insets: 5;-fx-border-width: 1;-fx-border-style: dashed;");
            }
        });

        setOnMouseClicked(e->selectAnnotation(null));
    }

    public void selectAnnotation(Annotation ann){
        selectedAnnotation.set(ann);
    }
}

这很有效 - 但是我无法因为我的FXML引用了这个 PaneWithSelectionListener 而不是 Pane ，所以我不再使用SceneBuilder了。我不确定如何将自定义窗格导入SceneBuilder。我已经查看了其他问题，它们都是FXML和控制器的组合 - 这只是窗格。

And this works great - however I am not able to work with SceneBuilder anymore since my FXML references this PaneWithSelectionListener rather than Pane. I am not sure how to get my custom pane into SceneBuilder. I have looked at other questions and they are all a combination of FXML and Controllers - where this is just a Pane.

有没有人知道这样做的方法，或者在初始化时将 Pane 换成 PaneWithSelectionListener ？

Does anyone know of a way to do this, or perhaps swap the Pane for a PaneWithSelectionListener at initialization time?

谢谢

推荐答案

如果问题只是为了让你的自定义在SceneBuilder中可用的类，您可以通过以下步骤完成：

If the issue is just to make your custom class available in SceneBuilder, you can do so with the following steps:

1. 捆绑您的自定义类（以及任何支持类，例如 Annotation ）作为jar文件


2. 在SceneBuilder中，激活左侧窗格顶部Library旁边的下拉按钮：
   


3. 选择导入JAR / FXML文件...


4. 选择从步骤1创建的Jar文件


5. 确保您需要在SceneBuilder中访问的类（ PaneWithSelec检查了ingListener ）


6. 按导入组件


7. PaneWithSelectionListener 现在将出现在左窗格中自定义下的SceneBuilder中：
   

1. Bundle your custom class (and any supporting classes, such as Annotation) as a jar file
2. In SceneBuilder, activate the drop-down button next to "Library" in the top of the left pane:
3. Choose "Import JAR/FXML File..."
4. Select the Jar file created from step 1
5. Make sure the class you need access to in SceneBuilder (PaneWithSelectionListener) is checked
6. Press "Import Component"
7. PaneWithSelectionListener will now appear in SceneBuilder under "Custom" in the left pane:

你会注意到SceneBuilder中的下拉菜单有一个自定义库文件夹选项，你可以从中打开文件夹jar文件存储。对于快速选项，您只需将jar文件复制到此文件夹（并在短暂延迟后），所包含的类将显示在自定义列表中。

You'll notice the drop-down in SceneBuilder has a "Custom Library Folder" option, from which you can open the folder where the jar files are stored. For a quick option, you can just copy jar files to this folder and (after a short delay), the contained classes will appear in the "Custom" list.
