The basic behavior of the layer is controlled by its LayerOptions property, an unsigned 32-bit integer field of bits. The upper 8 bits in this field are reserved for default options:
|Bit #||Constant Name||Description|
|31||LOB_VISIBLE||Controls the layer visibility|
Indicates that the layer performs drawing when its owner (TCustomImage32 control or its descendant) draws its GDI Overlays.
[ Note: Most likely, this constant will not be used in future versions. Do not use it ]
|29||LOB_MOUSE_EVENTS||Specifies whether the layer responds to mouse messages.|
|28||LOB_NO_UPDATE||Disables automatic repainting when the layer changes its location or other properties.|
|27||LOB_NO_CAPTURE||Allows to override automatic capturing of mouse messages when the left mouse is pressed on top of the layer. This bit has no effect if LOB_MOUSE_EVENTS is not set.|
|26||LOB_RESERVED_26||Reserved for future use|
|25||LOB_RESERVED_25||Reserved for future use|
|24||LOB_RESERVED_24||Reserved for future use|
Other 24 bits can be used for any other purpose, as customized layer classification etc.
