I am missing an option to send a changed from a ListBoxModel to (all) connected ListBoxes.
Whenever my model changes, I find myself hacking around adding ChangeListeners or redundant references, just to call ListBox::updateContent() or ListBox::resized() to force updates.
Is there something, that I overlooked? Otherwise it would be great, if an internal ListenerList could be added to the ListBoxModel. It could act completely under the hood, no need to add a public ListBoxModel::Listener or something.
(I saw this old thread, but I think there are better solutions)
