Description
Interface Summary | |
---|---|
ListCellRenderer | A "rubber stamp" tool that allows us to extract a component (often the same component instance for all invocations) that is initialized to the value of the current item extracted from the model, this component is drawn on the list and discarded. |
ListModel | Represents the data structure of the list, thus allowing a list to represent any potential data source by referencing different implementations of this interface. |
Class Summary | |
---|---|
DefaultListCellRenderer | Default implementation of the renderer based on a label see the ListCellRenderer
for more information about the use and purpose of this class. |
DefaultListModel | Default implementation of the list model based on a vector of elements. |
Lists are highly customizable and serve as the basis for ComboBox
and
other components (such as carousels etc) they employ a similar MVC approach to
Swing including the renderer pattern. ListCellRenderer
allows us to customize the appearance of a list entry, it works as a
"rubber stamp" by drawing the rendered component and discarding its state thus
allowing very large lists with very little component state overhead.
ListModel
allows us to represent the underlying
data structure for the List
/ComboBox
without requiring all the data to reside in memory or in a specific structure.
This allows a model to represent a data source of any type, coupled with the renderer the
data source can be returned in an internal representation state and still be rendered
properly to the screen.
