Java – close fxml window by code, javafx

fxmljavajavafxuser interface

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

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

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();
}

but it doesn't work!

All help will be greatly appreciated. Thanks!

  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();
}
