Access to ListView Cells

[Slavko Scekic]

Well, I think that ListView's selectionModel property is what you need, if
you want to change the process' state from within the GUI list (i.e. user
selects a row and issues a command). If you want to update process' state
programmatically, you can use ListView's getItems() method.

To my understanding, ListCell is intended only to display, not manipulate
data in this sense. So, if you have more than one possible state (i.e. node
to display), you'd change your StatusIndicator to look something like this:

StatusIndicator extends Parent {
        ...
        public Status getStatus() {
                return status;
        }
        public void setStatus(Status status) {
                if(status.equals(oneOption))
                {
                    this.graphic= oneOptionGraphic;
                }
                else
                {
                   this.praphic= anotherOptionGraphic;
                }
        }
        ...
}
Or something similar, this is just a guess based on your code.
