Getting id from a ActionEvent in JavaFX

Question

I have a group of ToggleButtons that need to find out their id. Currently I can check the id in the getSource() and toString() method like this:

@FXML
public void btnCell(ActionEvent actionEvent) {
    System.out.println(actionEvent.getSource());
}

Prints: ToggleButton[id=btn00, styleClass=toggle-button]''

Can I extract the id without relying on some shady substring busniess on that string?

Answer 1

In case this is still relevant, I use a whole bunch of programmatically generated buttons (representing menu items in a POS application), identified through MyButton.setUserData(MyProdID), which is loaded from the product IDs in a database table. Then you can get that with MyButton.getUserData() in the ActionEvent handler.

Answer 2

hope it helps:

import javafx.scene.Node;
.... 
@FXML
public void btnCell(ActionEvent actionEvent) {
   final Node source = (Node) actionEvent.getSource();
   String id = source.getId();
   Scene scene = source.getScene();
   scene.lookup("#"+id).getStyleClass() ;
}
