你好

我正在尝试开发一个 javafx 小应用程序。

我遇到了 javafx TabPane 问题。如果选项卡多于舞台无法显示，我将无法滚动到页面底部。

任何人的想法。

我用这个 css 也

.tab-pane *.tab-header-background {
    -fx-background-color: #000000;
}

.tab-pane  *.tab:selected {
    -fx-color: #FFFFFF;
}

结果如下

Tab Pane with scroll

出现箭头。

问题是我在页眉中有 30 个选项卡，但我无法滚动到最后一个。即使我 select 它通过箭头，它也不会出现

谢谢
