Property Value

The AnnPicture used when drawing the locked symbol for locked objects.

All objects inside the container will use this picture when drawing the object if the object is locked.

The container uses a picture of a "lock" that is created by default. You can change this default picture by using this property.

This property can be set to AnnPicture.Empty to remove the lock picture.
