- * ColumnLayout lays out components in a column. At
- * construction time, both horizontal orientation and vertical
- * orientation may be specified, along with the gap to use
- * between components.<p>
- *
- * Horizontal orientation must be one of the following:
- * <dl>
- * <dd> LEFT
- * <dd> CENTER
- * <dd> RIGHT
- * </dl>
- *
- * Vertical orientation must be one of the following:
- * <dl>
- * <dd> TOP
- * <dd> CENTER
- * <dd> BOTTOM
- * </dl>
