Member Function Documentation

virtual bool16 IGrabBehavior::CanFormNeedfulSet ( ) const

pure virtual

Can the source item be grabbed as NeedfulSet

Returns

true if "this" could have items in NeedfulSet

Implemented in CGrabBehavior.

virtual UIDList IGrabBehavior::GetNeedfulSet ( ) const

pure virtual

Returns UIDList of elements that would be part of the NeedfulSet for this item. It does not include the item's own UID. Only the items that should be part of set for this item are returned

Implemented in CGrabBehavior.

virtual UID IGrabBehavior::GetRootUID ( ) const

pure virtual

Returns UID of the outermost element that has IID_IGRABBEHAVIOR interface defined on it

Implemented in CGrabBehavior.
