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 numbers should be shown

Method Detail

refreshTheme

public void refreshTheme()

Description copied from class: Component

Makes sure the component is up to date with the current style object

Overrides:

refreshTheme in class Component

getCellRendererComponent

public Component getCellRendererComponent(Component list,
                                          java.lang.Object model,
                                          java.lang.Object value,
                                          int index,
                                          boolean isSelected)

Description copied from interface: CellRenderer

Returns a component instance that is already set to render "value". While it is not a requirement many renderes 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:

getCellRendererComponent in interface CellRenderer

Parameters:

list - the list component

model - the model behind the render

value - the value to render

index - the index in the list

isSelected - whether the entry is selected

Returns:

a component to paint within the list

getListCellRendererComponent

public Component getListCellRendererComponent(List list,
                                              java.lang.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 renderes 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 component

value - the value to render

index - the index in the list

isSelected - whether the entry is selected

Returns:

a component to paint within the list

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 parent list

Returns:

a component to use as focus

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

See Also:

Display

isShowNumbers

public boolean isShowNumbers()

Indicate whether numbering should exist for the default cell renderer

Returns:

true if numers are shown by the numbers

setShowNumbers

public void setShowNumbers(boolean showNumbers)

Indicate whether numbering should exist for the default cell renderer

Parameters:

showNumbers - indicate whether numbering should exist for the default cell renderer

getSelectionTransparency

public int getSelectionTransparency()

The background transparency factor to apply to the selection focus

Returns:

selection transperancy value

setSelectionTransparency

public void setSelectionTransparency(int selectionTransparency)

The background transparency factor to apply to the selection focus

Parameters:

selectionTransparency - the selection transperancy value

setShowNumbersDefault

public static void setShowNumbersDefault(boolean def)

Inidicates whether the default list cell renderer will show numbers by default when constructed

Parameters:

def - true to show numbers for all renderers created in the future

isShowNumbersDefault

public static boolean isShowNumbersDefault()

Inidicates whether the default list cell renderer will show numbers by default when constructed

Returns:

true when showing numbers, false otherwise

getFocusComponent

public Component getFocusComponent(Component list)

Description copied from interface: CellRenderer

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:

getFocusComponent in interface CellRenderer

Parameters:

list - the parent list

Returns:

a component to use as focus
