/**

 * only if the constraint given passes. If the constraint is null, it will
 * always pass.
 * <p/>
 * @param <T> the generic type of the cell.
 * @param contextMenu the context menu to show.
 * @param cellFactory the cell factory to use.
 * @param constraint the constraint placed on showing the context menu - it
 * will only be shown if this constraint passes, or it is null.
 * @return a callback that sets the given context menu on each cell.
