JavaFx:在fxml文件中设置窗口标题 [英] JavaFx : Set window title in fxml file

问题描述

我刚刚开始将JavaFx用于新的应用程序.

I'm just starting to use JavaFx for a new application.

我知道如何在Java代码中设置窗口标题，但是如何在fxml文件中设置窗口标题?

I know how to set the window title in the java code but how to set it in a fxml file ?

感谢您的帮助.

这是我的代码

@Override
public void start(Stage primaryStage) throws Exception {

    Parent root = FXMLLoader.load(getClass().getResource("Main.fxml"));
    primaryStage.setTitle(applicationName);
    primaryStage.setScene(new Scene(root));
    primaryStage.show();
}

我只想在Main.fxml中设置标题.

I just want set the title in Main.fxml.

推荐答案

要在FXML中设置舞台的标题，您需要在FXML中构建舞台，如下所示:

to set the title of the stage in FXML, you need to construct the stage in FXML, like this:

<?xml version="1.0" encoding="utf-8"?>

<?import javafx.scene.layout.VBox?>
<?import javafx.stage.Stage?>
<?import javafx.scene.Scene?>
<?import javafx.scene.control.Label?>

<Stage title="Some Stage">
  <scene>
    <Scene>
      <VBox xmlns:fx="http://javafx.com/fxml">
        <children>
          <Label text="John Doe"/>
        </children>
      </VBox>
    </Scene>
  </scene>
</Stage>

如果仅通过FXML构造场景的根元素(在我的示例中为VBox)，然后像您一样将其放入场景中(这是通常的方法)，则无法设置直接在FXML中添加标题(没有后面的代码).

If you only construct the root element of the scene (in my example, the VBox) via FXML and then put it into a scene afterwards like you do it (which is the common way), then it is impossible to set the title in FXML directly (without code behind).
