是否可以将包含自定义JavaFX控件的JAR导入Scene Builder？
[英]Is it possible to import a JAR containing a custom JavaFX control into Scene Builder?
问题描述
I was working on a stage when I noticed I practically had the exact same thing three times. 
我在一个舞台上工作时，发现我实际上有三遍完全一样的东西。 Rather than that (since I hate that), I decided to take what I had those 3 times and turn it into a custom component. 而不是那样（因为我讨厌那样），我决定将这3次所用的东西变成一个自定义组件。
Now I know I can add it in code but I can't predict the layout behavior (two of these will be going into tabs directly, and the third will be going into a grid pane). 现在，我知道可以在代码中添加它，但是我无法预测布局行为（其中两个将直接进入选项卡，而第三个将进入网格窗格）。
I tried importing the .jar that contained the control into Scene Builder. 我尝试将包含控件的.jar导入Scene Builder。 A dialog popped up asking me what in the JAR I wanted to import but it was completely empty. 弹出一个对话框，询问我要导入的JAR文件是什么，但它完全是空的。
I've seen before that some individuals have added "custom controls" (a term which I use loosely) only to find that basically it just dumps a bunch of components together to form the control. 我之前看到有些人添加了“自定义控件”（我经常使用的术语），只是发现基本上它只是将一堆组件转储在一起以形成控件。 That may work for some people but I'm not looking for that. 这可能对某些人有用，但我不是在寻找那个。 To clarify 澄清
what I DO want (were I to look into the FXML code): 我想要的是什么（我要研究FXML代码）：
<DGCSDefiner //other layout related XML code/>
what I do NOT want: 我不想要的：
<GridPane //bla bla XML layout code>
<columnConstraints>
//bla bla column constraint stuff
</columnConstraints>
//etc, etc
</GridPane>
Is this possible? 这可能吗？ I'm coming off of C# and VS2010 again and I'm a bit spoiled when it comes to custom controls so if it's at all possible to make something like that happen, can someone tell me how? 我再次脱离C＃和VS2010，在自定义控件方面有点受宠若惊，因此，如果有可能实现类似的功能，有人可以告诉我如何做吗？
Is it possible to import a compiled JAR file containing a custom JavaFX control into Scene Builder, such that dropping it in from the library will result in what I described up there? 是否可以将包含自定义JavaFX控件的已编译JAR文件导入Scene Builder，以便将其从库中放入，将得到我在此处描述的内容？
EDIT 1 Okay this is what I have in my FXML file. 编辑1好的，这就是我的FXML文件中的内容。 According to mlody991, I need 3 files to make this work: The FXML file (Built with SceneBuilder): 根据mlody991，我需要3个文件才能完成此工作：FXML文件（与SceneBuilder一起内置）：

Is it possible for someone to explain to me the purpose of this last file? 有人可以向我解释最后一个文件的目的吗？ What is it's function? 它有什么作用？ I can see from the example code with which I was furnished it has been set as the FXML Controller but that still tells me nothing. 我可以从提供的示例代码中看到它已被设置为FXML Controller，但这仍然告诉我什么。 I've never really even set an FXML controller before since I typically do it in code, so is it's purpose explicitly to make this control importable into the Scene Builder? 自从我通常在代码中进行操作以来，我从来没有真正设置过FXML控制器，因此是否明确要使此控件可导入到Scene Builder中？
EDIT 2 Okay. 编辑2好的。 I had a hunch and it proved correct but it did not help. 我有一种预感，事实证明它是正确的，但没有帮助。 I removed the control CSS stylesheet reference and it allowed me to add the control, no problem. 我删除了控件CSS样式表引用，并允许我添加控件，没问题。
However when I dropped it in this was what happened in the FXML file: 但是，当我将其放入其中时，FXML文件中发生了什么：

in the FXML code after I drag and drop the custom control into the designer. 在将自定义控件拖放到设计器中后，在FXML代码中单击。 Is that possible? 那可能吗？ Do I need to compile it into a jar? 我需要将其编译到罐子中吗？
Edit 3 To make it a bit more clear, this is exactly what I want to see happen. 编辑3为了更清楚一点， 这正是我想看到的。 This looks good but the problem is there is no information about how to import a custom control into Scene Builder such that when I Drag 'n Drop it onto the canvas, I only get somewhere in the neighborhood of a single line of code, vs the book and a half it's writing (which is just silly. If I wanted that I could (and would) do it myself). 这看起来不错，但问题是没有关于如何将自定义控件导入到Scene Builder中的信息，因此当我将其拖放到画布上时，我只会在一行代码的附近找到某个位置，而一本书有一半是写作（这很愚蠢。如果我想我可以（也愿意）自己做）。

You do not need .jar file to do that. 您不需要.jar文件来执行此操作。 You can simply create new FXML file with that what you need ex. 您可以简单地使用所需的内容创建新的FXML文件。 combo box. 组合框。 Create class file with extending combo box, controller and add controller in FXML file (in scene builder). 使用扩展的组合框，控制器创建类文件，并在FXML文件中添加控制器（在场景构建器中）。
Find "Import from JAR/FXML file" in combo box near to left search box in scene builder and then select the file. 在场景构建器中左侧搜索框附近的组合框中找到“从JAR / FXML文件导入”，然后选择文件。 Now you have new title pane in left accordion with name Custom. 现在，您在左手风琴中有了一个名为Custom的新标题窗格。 There you can find your components. 在这里可以找到您的组件。
