Layer |
The Layer property of a Screen defines in which layers a Screen object must appear. This value represents a 32-bit mask, one bit for each layer. Therefore, users can define up to 32 individual layers. Thus, Screen objects can be grouped logically and displayed or hidden only by changing the mask of the Layer property.
