User contributed notes
In extensions included in the Joomla! release, display methods typically consist of a collection of calls to the view's related model method, supplemented with additional logic to prepare data for display before calling the parent display() function which in turn takes responsibility for the template display. The model calls are somewhat standardized depending on the related model class that is used (or derived from).
JModelAdmin (typically back end single object creation/editing)
$this->form = $this->get('Form'); // gets the form definition that will be $this->item = $this->get('Item'); //when the corresponding model is JModelItem or a subclass $this->state = $this->get('State');
JModelList (typically back end views that display a collection of objects)
$this->items = $this->get('Items'); $this->pagination = $this->get('Pagination'); $this->state = $this->get('State');
JModelAdmin, JModelList and their descendants usually provide a method called addToolbar() which provides the logic to display the icons and action selections in back end extensions.
JModelItem (typically front end views of object(s) )
$this->state = $this->get('State'); $this->item = $this->get('Item')
