Class ResetDTCRColorHighlighter

java.lang.Object

org.jdesktop.swingx.decorator.AbstractHighlighter

org.jdesktop.swingx.decorator.ColorHighlighter

org.jdesktop.swingx.decorator.ResetDTCRColorHighlighter

All Implemented Interfaces:

Highlighter

public class ResetDTCRColorHighlighter
extends ColorHighlighter

This is a hack around DefaultTableCellRenderer color "memory", see Issue #258-swingx.

The issue is that the default has internal color management which is different from other types of renderers. The consequence of the internal color handling is that there's a color memory which must be reset somehow. The "old" hack around reset the xxColors of all types of renderers to the adapter's target XXColors, introducing #178-swingx (Highlighgters must not change any colors except those for which their color properties are explicitly set).

This hack limits the interference to renderers of type DefaultTableCellRenderer, applying a hacking highlighter which resets the renderers XXColors to a previously "memorized" color. Note that setting the color to null didn't have the desired effect.

PENDING: extend ColorHighlighter

Method Details

highlight

public Component highlight(Component renderer,
 ComponentAdapter adapter)

applies the memory hack for renderers of type DefaultTableCellRenderer, does nothing for other types.

Specified by:

highlight in interface Highlighter

Overrides:

highlight in class AbstractHighlighter

Parameters:

renderer - the component to highlight

adapter - the renderee's component state.

Returns:

the decorated cell rendering component

applyBackground

protected void applyBackground(Component renderer,
 ComponentAdapter adapter)

Description copied from class: ColorHighlighter

Applies a suitable background for the renderer component within the specified adapter.

This implementation applies its background or selectedBackground color (depending on the adapter's selected state) if != null. Otherwise it does nothing.

Overrides:

applyBackground in class ColorHighlighter

Parameters:

renderer - the cell renderer component that is to be decorated

adapter - the ComponentAdapter for this decorate operation

applyForeground

protected void applyForeground(Component renderer,
 ComponentAdapter adapter)

Description copied from class: ColorHighlighter

Applies a suitable foreground for the renderer component within the specified adapter.

This implementation applies its foreground or selectedfForeground color (depending on the adapter's selected state) if != null. Otherwise it does nothing.

Overrides:

applyForeground in class ColorHighlighter

Parameters:

renderer - the cell renderer component that is to be decorated

adapter - the ComponentAdapter for this decorate operation
