java.lang.Objectorg.jdesktop.swingx.renderer.CellContext
public class CellContext
Encapsulates a snapshop of cell content and default display context
for usage by a ComponentProvider
.
One part is the super-set of properties that's traditionally passed into the core renderers' (Table-, List-, Tree-) getXXCellRendererComponent. Raw properties which define the context are
PENDING JW: the generic parameterization is useful to have a type-safe installContext but introduces a bunch of generic warnings. Not enough reason to go for, so will be removed in future versions (see Issue 1042-swingx)
