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!

give your close button an fx:id, if you haven't yet:

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();

}
