Package org.eclipse.nebula.widgets.xviewer

Class XViewerValueColumn

java.lang.Object

org.eclipse.nebula.widgets.xviewer.core.model.XViewerColumn

org.eclipse.nebula.widgets.xviewer.XViewerValueColumn

All Implemented Interfaces:

IXViewerValueColumn

Direct Known Subclasses:

XViewerComputedColumn

public class XViewerValueColumn
extends XViewerColumn
implements IXViewerValueColumn

This class provides XViewerColumns another mechanism to providing text, background color and foreground color instead of through the XViewerLabelProvider. XViewerLabelProvider will call the provided routines to try to populate the column and only if null/empty string will default to the normal label provider methods. This allows for XViwerColumns to be shared between XViewers and/or have XViewerColumns provide their own values through the same class that defines the column.
