Getting selected element from ListView

Question

I modify a ListView with the results from a database search in order to use that selection to make another DB request later on.

I want to get the field

Answer 1

You can make a custom event handler, first make a class to handle mouse events.

import javafx.event.EventHandler;
import javafx.scene.input.MouseEvent;

class ListViewHandler implements EventHandler {
    @Override
    public void handle(MouseEvent event) {
        //this method will be overrided in next step
    }
 }

After making the class, go to where you want the event to happen

 list.setOnMouseClicked(new ListViewHandler(){
        @Override
        public void handle(javafx.scene.input.MouseEvent event) {
            System.out.print(list.getSelectionModel().getSelectedIndex());
        }
 });
