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
当我注意到我几乎完全有同样的事情三次时，我正在一个舞台上工作。而不是那个（因为我讨厌那个），我决定拿走我的那些3次并把它变成一个自定义组件。
I was working on a stage when I noticed I practically had the exact same thing three times. Rather than that (since I hate that), I decided to take what I had those 3 times and turn it into a custom component.
现在我知道我可以添加它在代码中，我无法预测布局行为（其中两个将直接进入选项卡，第三个将进入网格窗格）。
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).
I尝试将包含控件的.jar导入Scene Builder。弹出一个对话框，询问我想要导入的JAR中的内容，但它完全是空的。
I tried importing the .jar that contained the control into Scene Builder. A dialog popped up asking me what in the JAR I wanted to import but it was completely empty.
我之前看到有些人添加了自定义控件（一个我松散使用的术语）只是发现基本上它只是将一堆组件一起转储以形成控件。这可能适用于某些人，但我不是在寻找。澄清
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. That may work for some people but I'm not looking for that. To clarify
我想要的是什么（我是否要查看FXML代码）：
what I DO want (were I to look into the FXML code):
<DGCSDefiner //other layout related XML code/>
我不想要的东西：
<GridPane //bla bla XML layout code>
<columnConstraints>
//bla bla column constraint stuff
</columnConstraints>
//etc, etc
</GridPane>
这可能吗？我再次离开C＃和VS2010而且在自定义控件方面我有点被宠坏了所以如果有可能做出类似的事情，有人会告诉我怎么样？
Is this possible? 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?
是否可以将包含自定义JavaFX控件的已编译JAR文件导入到Scene Builder中，以便将其从库中删除将导致我在那里描述的内容？
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?

好的，这就是我在FXML文件中的内容。根据mlody991，我需要3个文件来完成这项工作：
FXML文件（使用SceneBuilder构建）：

有人可以向我解释这最后一个档案的目的吗？它的功能是什么？我可以从我提供的示例代码中看到它已被设置为FXML控制器，但仍然没有告诉我什么。我之前从未真正设置过FXML控制器，因为我通常在代码中执行此操作，因此明确的目的是将此控件导入到Scene Builder中吗？
Is it possible for someone to explain to me the purpose of this last file? What is it's function? 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. 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?
编辑2 好的。我有预感，事实证明这是正确的，但没有用。我删除了控件CSS样式表引用，它允许我添加控件，没问题。
EDIT 2 Okay. I had a hunch and it proved correct but it did not help. I removed the control CSS stylesheet reference and it allowed me to add the control, no problem.
然而当我放弃它时，FXML文件中发生了什么：
However when I dropped it in this was what happened in the FXML file:

What I would like to see is something to the effect of this:

<content>
<DGCSDefiner/>
</content>
</Tab>
。
这可能吗？我是否需要将其编译成jar？
in the FXML code after I drag and drop the custom control into the designer. Is that possible? Do I need to compile it into a jar?
编辑3
为了使其更清晰，这个正是我想要看到的。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，这样当我将它拖放到画布上时，我只能在一行代码的某处附近，而不是书和一半它的写作（这是愚蠢的。如果我想我可以（并且会）自己做。）
Edit 3 To make it a bit more clear, this is exactly what I want to see happen. 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).
推荐答案
你不需要.jar文件来做到这一点。你可以简单地用你需要的东西创建新的FXML文件。组合框。使用扩展组合框创建类文件，控制器并在FXML文件中添加控制器（在场景构建器中）。
You do not need .jar file to do that. You can simply create new FXML file with that what you need ex. combo box. Create class file with extending combo box, controller and add controller in FXML file (in scene builder).
在附近的组合框中查找从JAR / FXML文件导入在场景构建器中左侧搜索框，然后选择该文件。现在左手风琴的新标题窗格名为Custom。在那里你可以找到你的组件。
Find "Import from JAR/FXML file" in combo box near to left search box in scene builder and then select the file. Now you have new title pane in left accordion with name Custom. There you can find your components.
@edit
有文件。
