java - 删除辅助选项卡

Question

我有应用程序布局:

/image/YsK5R.png

由于编写代码，我得到了这个

/image/j2Nym.png

问题:如何删除带有关闭选项卡的顶行并仅保留布局上的内容？

这个问题是这个问题的双重:https://ru.stackoverflow.com/questions/941060/%D0%A3%D0%B1%D1%80%D0%B0%D1%82%D1%8C-%D0%B2%D1%82%D0%BE%D1%80%D0%B8%D1%87%D0%BD%D1%8B%D0%B5-%D0%B2%D0%BA%D0%BB%D0%B0%D0%B4%D0%BA%D0%B8

Answer 1

有很多方法可以做到这一点，具体取决于您想要添加到应用程序/布局中的通用性。

但最重要的是，您似乎因混淆 TabPane 和 Tab 而犯了一个错误。第一个是容器，第二个对应于您可能拥有的每个选项卡。通常您有一个 TabPane，其中包含许多 Tab(即使没有必要)。

一种解决方案可能是通过执行此操作来修改您的方法 showTab(阅读评论)

private void showTab() {
    try {
        // Tab 1 loader
        FXMLLoader loaderTab1 = new FXMLLoader(Main.class.getResource("Tab1.fxml"));
        // Tab 2 loader
        FXMLLoader loaderTab2 = new FXMLLoader(Main.class.getResource("Tab2.fxml"));

        TabPane tabPane = new TabPane();

        // Remove the 4 following lines, Tabs are already declared in FXML
        //Tab tab1 = new Tab();
        //Tab tab2 = new Tab();
        //tab1.setContent(loaderTab1.load());
        //tab2.setContent(loaderTab2.load());
        Tab tab1 = loaderTab1.load();
        Tab tab2 = loaderTab2.load();

        tabPane.getTabs().addAll(tab1,tab2);

        rootLayout.setCenter(tabPane);

    } catch (IOException e){
        e.printStackTrace();
    }
}

并更改您的 FXML 文件，如下所示(TabPane 和选项卡标签已删除):

<Tab xmlns="http://javafx.com/javafx/10.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Tab1Controller" text="Tab1">
