我有一个不可调整大小的设置面板，它变得很拥挤，所以我决定将包含设置的网格 Pane 添加到滚动 Pane 中。问题是应用程序启动时滚动 Pane 从底部开始。奇怪的是我将 HValue 设置为 0，它应该从顶部开始。这是在场景生成器中显示它的 gif:https://gyazo.com/f10a1641b8357e4fc30cd180c0425dae 根本没有代码与滚动 Pane 交互，正如您所看到的，场景生成器预览窗口也有相同的问题，因此它与 FXML 有关。要重现它，您可以简单地使用下面共享的 fxml 自己设置一个 javafx 项目，然后运行它并查看滚动条如何跳到底部。 完整的 FXML 文件:https://pastebin.com/aS3Dn3pH 。 仅滚动 Pane 内容的片段:

最佳答案
将 focusTraversable="false" 添加到网格 Pane 中的每个节点解决了该问题。
问题在于，它在启动时将注意力集中在底部的按钮上，从而将 slider 移动到那里。该解决方案只是简单地实现了这样，在没有用户输入的情况下，没有任何东西会被随机聚焦。
