The item is added to the end of the items maintained by its parent.The style value is either one of the style constants defined in class SWTwhich is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using theint"|" operator) two or more of thoseSWTstyle constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.- Parameters:
- parent- a widget which will be the parent of the new instance (cannot be null)
- style- the style of item to construct
- Throws:
- IllegalArgumentException-- ERROR_NULL_ARGUMENT - if the parent is null
 
- SWTException-- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
