How can I detect JavaFx double click on listView

Question

I just finished writing a code that open an element after clicking on it on the listView. But I wish to add a feature that allows user to modify that element, so user double clicks on the element to modify and simple clicks it to show his pannel . Any solution for that ? Thank you

Use the setOnMouseClicked in a custom CellFactory .

yourListView.setCellFactory(lv -> new ListCell<YourObject>()
{
    @Override
    public void updateItem(YourObject item, boolean empty)
    {
        super.updateItem(item, empty);
        if (empty) {
            setText(null);
            setGraphic(null);
        }
        else {
            //do other stuff here
            setOnMouseClicked(mouseClickedEvent -> {
                if (mouseClickedEvent.getButton().equals(MouseButton.PRIMARY) && mouseClickedEvent.getClickCount() == 2) {
                    System.out.println("double clicked");                       
                }
            });
        }
    }
});
