按代码关闭fxml窗口，javafx [英] close fxml window by code, javafx

问题描述

我需要通过控制器中的代码关闭当前的fxml窗口

I need to close the current fxml window by code in the controller

我知道stage.close（）或stage.hide（ ）在fx中执行此操作

I know stage.close() or stage.hide() do this in fx

如何在fxml中实现此功能？我试过

how to implement this in fxml? I tried

private void on_btnClose_clicked(ActionEvent actionEvent) {
        Parent root = FXMLLoader.load(getClass().getResource("currentWindow.fxml"));    
        Scene scene = new Scene(root);

        Stage stage = new Stage();            
        stage.setScene(scene);
        stage.show();
}

但它不起作用！

非常感谢所有帮助。谢谢！

All help will be greatly appreciated. Thanks!

推荐答案

1. 给你的关闭按钮一个fx：id，如果你还没有： < Button fx：id =closeButtononAction =＃closeButtonAction>



2. 在您的控制器类中：

1. give your close button an fx:id, if you haven't yet: <Button fx:id="closeButton" onAction="#closeButtonAction">

2. In your controller class:

@FXML private javafx.scene.control.Button closeButton;

@FXML
private void closeButtonAction(){
    // get a handle to the stage
    Stage stage = (Stage) closeButton.getScene().getWindow();
    // do what you have to do
    stage.close();
}
