Binding – JavaFX passes FX: ID to the controller or parameter in the fxml onAction method

Is there a way to pass parameters to the onAction method in the fxml file? Or can I get the FX: ID of the component that calls the onAction method in some way?

I have several buttons that should do the same thing, such as five buttons with IDS button1 – button 5. When pressed, the corresponding numbers 1-5 should be printed I don't want five onAction methods that are the same as this variable

Any help, appreciation,

Solution

Call only one handler, ActionEvent Source is the object that initiates the event

Try this:

myButton1.setOnAction(new MyButtonHandler());
myButton2.setOnAction(new MyButtonHandler());

private class MyButtonHandler implements EventHandler<ActionEvent>{
    @Override
    public void handle(ActionEvent evt) {
        if (evt.getSource().equals(myButton1)) {
          //do something
        } else if (evt.getSource().equals(myButton2)) {
          //do something
        }
    }
}

or

myButton1.addEventHandler(ActionEvent.ACTION,new MyButtonHandler());
myButton2.addEventHandler(MouseEvent.CLICKED,new MyButtonHandler());

private class MyButtonHandler implements EventHandler<Event>{
    @Override
    public void handle(Event evt) {
        if (evt.getSource().equals(myButton1)) {
          //do something
        } else if (evt.getSource().equals(myButton2)) {
          //do something
        }
    }
}
