JavaFX 无效属性

Question

我使用 Scene Builder 构建了一个场景，但在尝试使用 FXMLLoader 打开 fxml 文件时出现了一些错误。我的 JavaFX 版本是 2.2.55-b13。这是我的 fxml：

<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.collections.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>

<?import javafx.scene.paint.*?>
<?import javafx.scene.text.*?>

还有堆栈跟踪：

指定的行对我来说看起来不错，我在其他 fxml 文件中使用了其中一些属性，它们在那里工作正常......

Answer 1

我通过删除解决了这个问题：

<opaqueInsets>
            <Insets bottom="20.0" left="20.0" right="20.0" top="20.0" />
</opaqueInsets>

我的实际 JavaFX 版本与 SceneBuilder 的版本之间似乎存在一些兼容性问题
