Constructor & Destructor Documentation

SGFrameGroup::SGFrameGroup (  SuperGallery *  ParentGal,
Document *  ParentDoc = NULL,
Library *  ParentLib = NULL,
BOOL  IsForeground = TRUE
) 
 

SGFrameGroup constructor. Initialises the Group's parent pointers to point at its parent(s). Note that generally speaking, one of ParentDoc, ParentLib will be NULL, and the other will be non-NULL.

Author:

Date:
16/4/97 (Based on Jason's Layer gallery code)
Parameters:
ParentGal - points to the SuperGallery object which 'owns' this node [INPUTS] ParentDoc - NULL, or a pointer to the document this group references ParentLib - NULL, or a pointer to the library this group references
Notes: This constructor does nothing - jusat passes the call on to the baseclass constructor of identical proportions.

Member Function Documentation

SGFrameGroup::CC_DECLARE_DYNAMIC (  SGFrameGroup   )  [private]
 

BOOL SGFrameGroup::HandleEvent (  SGEventType  EventType,
void *  EventInfo,
SGMiscInfo *  MiscInfo
)  [virtual]
 

Handles a SuperGallery DisplayTree event.

Author:

Date:
16/4/97 (Based on Jason's Layer gallery code)
Parameters:
See SGDisplayNode::HandleEvent [INPUTS]
Returns:
TRUE if the event was handled successfully FALSE if it was not
Notes: This overrides the SGDisplayNGroup::HandleEvent method, to give a group-type thing which does wierd stuff for layer galleries (i.e. does not fold, and gives column titles in the 'group' display)
