Method Summary

Component	getListCellRendererComponent(List list, Object value, int index, boolean isSelected) Returns a component instance that is already set to render "value".
Component	getListFocusComponent(List list) Returns a component instance that is painted under the currently focused renderer and is animated to provide smooth scrolling.
int	getSelectionTransparency() The background transparency factor to apply to the selection focus.
boolean	isShowNumbers() Indicate whether numbering should exist for the default cell renderer.
void	repaint() Overriden to do nothing and remove a performance issue where renderer changes perform needless repaint calls.
void	setSelectionTransparency(int selectionTransparency) The background transparency factor to apply to the selection focus.
void	setShowNumbers(boolean showNumbers) Indicate whether numbering should exist for the default cell renderer.

Constructor Detail

DefaultListCellRenderer

public DefaultListCellRenderer()

Creates a new instance of DefaultCellRenderer.

DefaultListCellRenderer

public DefaultListCellRenderer(boolean showNumbers)

Creates a new instance of DefaultCellRenderer.

Parameters:

showNumbers - indicates whether numbers are shown

Method Detail

getListCellRendererComponent

public Component getListCellRendererComponent(List list,
                                              Object value,
                                              int index,
                                              boolean isSelected)

Description copied from interface: ListCellRenderer

Returns a component instance that is already set to render "value". While it is not a requirement many renderers often derive from a component (such as a label) and return "this". Notice that a null value for the value argument might be sent when refreshing the theme of the list.

Specified by:

getListCellRendererComponent in interface ListCellRenderer

Parameters:

list - the List object

value - an Object

index - the index

isSelected - indicating whether the Component is selected

Returns:

a Component object

getListFocusComponent

public Component getListFocusComponent(List list)

Description copied from interface: ListCellRenderer

Returns a component instance that is painted under the currently focused renderer and is animated to provide smooth scrolling. When the selection moves, this component is drawn above/bellow the list items - it is recommended to give this component some level of transparency (see above code example). This method is optional an implementation can choose to return null.

Specified by:

getListFocusComponent in interface ListCellRenderer

Parameters:

list - the list

Returns:

a component instance that is painted under the currently focused renderer and is animated to provide smooth scrolling.

See Also:

Component.setSmoothScrolling(boolean)

repaint

public void repaint()

Overriden to do nothing and remove a performance issue where renderer changes perform needless repaint calls.

Overrides:

repaint in class Component

isShowNumbers

public boolean isShowNumbers()

Indicate whether numbering should exist for the default cell renderer.

Returns:

true if numbering should exist for the default cell renderer

setShowNumbers

public void setShowNumbers(boolean showNumbers)

Indicate whether numbering should exist for the default cell renderer.

Parameters:

showNumbers - indicates if numbering should exist for the default cell renderer

getSelectionTransparency

public int getSelectionTransparency()

The background transparency factor to apply to the selection focus.

Returns:

the background transparency factor

See Also:

setSelectionTransparency(int)

setSelectionTransparency

public void setSelectionTransparency(int selectionTransparency)

The background transparency factor to apply to the selection focus.

Parameters:

selectionTransparency - the background transparency factor
