Access to ListView Cells

[Will Hoover]

Hi Jonathan, 

I have a ListView that contains custom ListCells which have a node that
visually indicates a status of a business process and a label for the
process name. I would like to be able to allow the user to set the status of
an item at any given time. How would I do so without accessing the cell from
myListView?

myListView.setCellFactory(new Callback<ListView<String>, ListCell<String>>()
{
	public ListCell<String> call(ListView<String> list) {
		return new NodeStatusView();
	}
});

NodeStatusView extends ListCell<String> {
	...
	StatusIndicator statusIndicator;
	...
	public void updateItem(String item, boolean empty) {
		super.updateItem(item, empty);
		if (!empty && item != null) {
			setText(item);
			myStatusNode = new StatusIndicator();
			setGraphic(this.myStatusNode);
		}
	}
	...
	public StatusIndicator getStatusIndicator() {
		return statusIndicator;
	}
	...
}

StatusIndicator extends Parent {
	...
	public Status getStatus() {
		return status;
	}
	public void setStatus(Status status) {
		this.status = status;
	}
	...
}

There isn't any API to access the cells within a ListView, unless you
provide the cell factory yourself. It would be useful to understand your use
case for wanting to access the cells outside of a cell factory.
