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

Handles a SuperGallery DisplayTree event.

Author:
Jason_Williams (Xara Group Ltd) <camelotdev@xara.com>
Date:
27/1/95 (base generated in sgbase.cpp)
Parameters:
EventType - An enumerated value describing what type of event is to be processed [INPUTS]
EventInfo - A structure describing the event (may be NULL). The exact thing pointed at by this pointer depends upon the event type:

MonoOn Event Thing EventInfo points at SGEVENT_FORMAT (SGFormatInfo *) SGEVENT_REDRAW (SGRedrawInfo *) SGEVENT_MOUSECLICK (SGMouseInfo *) MonoOff Use the provided SGDisplayNode::Get[Format]Info() inlines to retrieve this information - they provide useful error/type checking, and hide the cast

MiscInfo - always provided. Contains a few useful bits of info that may be needed for all event types.

Parameters:
FormatInfo is updated as appropriate [OUTPUTS]
Returns:
TRUE if the event was handled successfully FALSE if it was not
Notes: This overrides the pure virtual SGDisplayNode::HandleEvent method

A node need not handle a specific event - if it does not handle it, it should return FALSE.

Redraw and Formatting handlers should never return TRUE, as this will prevent the event from continuing through the tree.

Non-leaf-nodes must call SGDisplayNode::GiveEventToMyChildren in order to pass the event dow the tree. THIS node is a leaf-node, so it doesn't.
