当我在舞台上工作时，我发现我几乎经历了三次完全相同的事情。与此相反（因为我讨厌那样），我决定将这 3 次的内容转化为自定义组件。
现在我知道我可以在代码中添加它，但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）。
我尝试将包含控件的 .jar 导入到场景生成器中。弹出一个对话框，询问我想要导入 JAR 中的内容，但它完全是空的。
我之前见过一些人添加了“自定义控件”（我宽松地使用的术语），结果发现基本上它只是将一堆组件转储在一起以形成控件。这可能对某些人有用，但我并不是在寻找它。澄清
我想要什么（如果我查看 FXML 代码）：
<DGCSDefiner //other layout related XML code/>
我不想要什么：
<GridPane //bla bla XML layout code>
<columnConstraints>
//bla bla column constraint stuff
</columnConstraints>
//etc, etc
</GridPane>
这可能吗？我再次摆脱了 C# 和 VS2010，当谈到自定义控件时我有点被宠坏了，所以如果有可能实现这样的事情，有人可以告诉我如何做吗？
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结果？
EDIT 1好的，这就是我的 FXML 文件中的内容。根据 mlody991 的说法，我需要 3 个文件才能完成这项工作： FXML 文件（使用 SceneBuilder 构建）：

有人可以向我解释最后一个文件的用途吗？它的作用是什么？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，但这仍然告诉我什么。我以前从未真正设置过 FXML 控制器，因为我通常在代码中进行设置，那么它的目的是否明确是使该控件可导入到场景生成器中？
EDIT 2好的。我有一种预感，事实证明它是正确的，但没有帮助。我删除了控件 CSS 样式表引用，它允许我添加控件，没有问题。
然而，当我将其放入 FXML 文件中时，发生了以下情况：
它是这样的（仅显示相关部分）：

将自定义控件拖放到设计器中后，在 FXML 代码中。 那可能吗？我需要将其编译成jar吗？
Edit 3为了更清楚一点，this这正是我希望看到的事情发生。这看起来不错，但问题是没有关于如何将自定义控件导入场景生成器的信息，这样当我将其拖放到画布上时，我只能到达单行代码附近的某个位置，而不是它正在写一本书半（这很愚蠢。如果我愿意，我可以（并且愿意）自己做）。
您不需要 .jar 文件来执行此操作。您可以简单地使用您需要的内容创建新的 FXML 文件。组合框。创建带有扩展组合框、控制器的类文件，并在 FXML 文件中添加控制器（在场景生成器中）。
在场景生成器中左侧搜索框附近的组合框中找到“从 JAR/FXML 文件导入”，然后选择该文件。现在，您在左侧手风琴中有一个名为“自定义”的新标题窗格。在那里您可以找到您的组件。
@编辑 有文件。

下一步是添加到场景生成器
你可以添加这个组件。
