JavaFX get textbox from childSet thats within pane where button was pressed

[David Go]

Hey all I am confused as to why this childSet is not accessible to my btnP variable even though its stated in the list?


I am trying to get the TextField ID from within the inside of the pane that both the button and textfield are inside.



The only "child" I have to choose from for btnP is ChildrenUnmodifiable().

Would be great if someone could shed some light on this!

Hey David, don't you have your controls defined in your controller with @FXML annotation like that?

@FXML
private Button scanBtn;
    
@FXML
private TextField relayerIP;

When I click on scanBtn I don't need to get its parent if I need access to my text field, I just use relayerIP in my case. For ecample:

class ScanButtonHandler extends CustomEventHandler {
        @Override
        public void handle(ActionEvent actionEvent) {
            
            relayerIP.setText("blah-blah-blah");
}

The whole controller looks like below:

public class ScannerController {
    private final Logger logger = LoggerFactory.getLogger(getClass());
    @FXML
    private Button scanBtn;
   
    @FXML
    private TextField relayerIP;

    //This is an inner class
    class ScanButtonHandler extends CustomEventHandler {
        @Override
        public void handle(ActionEvent actionEvent) {
            
            relayerIP.setText("blah-blah-blah");
        }
}

If you need to get a child set you just can you use btnP.getChildren(), it returns a list with children then it's up to yo how to find an object you need
