Question

我创建了一个TabPane，其中有4个标签，每个标签中都有按钮。每次我运行我的应用程序时，在第一次运行时它总是显示我已经按下了“维护问题”。标签当然不是真的Like in this picture。如何更改它，以便在打开应用程序时它不会从选项卡中显示任何内容？我是用场景构建器做的，所以这里是我的fxml代码：

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.*?>
<?import javafx.scene.effect.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.text.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane fx:id="anchorPane" focusTraversable="false" prefHeight="570.0" prefWidth="861.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="application.TeacherWindowController">

如果没有很多'hacky workarounds'，我认为这是不可能的。虽然从图片看起来你似乎将它用作Menu？那你为什么不试试MenuBar而不是TabPane？

以下是MenuBars上的一个不错的tutorial，可能会帮助您入门。
