Add EventFilter via fxml

Question

now i can do this

public TextField lastmonthbox;
public void initialize()throws Exception{
    lastmonthbox.addEventFilter(KeyEvent.KEY_TYPED, new EventHandler<KeyEvent>() {
        public void handle( KeyEvent t ) {
            char ar[] = t.getCharacter().toCharArray();
            char ch = ar[t.getCharacter().toCharArray().length - 1];
            if (!(ch >= '0' && ch <= '9' || ch=='.')) {
                System.out.println("The char you entered is not a number");
                t.consume();
            }
        }
    });

}

is there way to add eventfilter via fxml, looks like onAction="#someFunction"??

i not found any list or tutorial about all possible tags in fxml(

Answer 1

AFAIK No but you can always customize the controls according to your needs. For example like

<MyTextField ... onKeyTypedFilter="#yourFilter" />

then do some reflection staff in backend. However is it worth?

Answer 2

Following Uluk's answer, you can do something like this. There's no reflection required as the FXMLLoader already takes care of converting "#..." to an EventHandler object.

Note that this is just the structure: this isn't a particularly robust way of creating a numeric-only text field. For example, the user can copy and paste arbitrary text in there, using either keystrokes or the mouse.
