打开应用程序时，在Tabpane Javafx中更改选项视图

Question

I created a TabPane that has 4 tabs in it and each tab has buttons in it. Every time I run my application, at the first run it always shows like I already pressed on the 'Maintain Questions' tab which is of course not true Like in this picture . How can I change it that it will show me nothing from the tabs when I open the application? I did it with the scene builder so here is my fxml code:

<?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">

Answer 1

I dont think that is possible without a lot of 'hacky workarounds'. Though from the Picture it seems like you use it as a Menu ? So why don't you try the MenuBar instead of a TabPane ?

Here is a nice tutorial on MenuBars which might help you get started.
