| This DisplayTree node type is used by the SuperGallery This is a virtual class from which all nodes in the DisplayTree are derived. More... | |
| class | SGDisplayRoot |
| This DisplayTree node type is used by the SuperGallery The top (root) level of the DisplayTree is made up of a single SGDisplayRoot node. This node is used as a single entry-point for all tree-wide actions which the SuperGallery applies to it (redraw, reformatting, etc). More... | |
| class | SGDisplayRootScroll |
| This DisplayTree node type is used by the SuperGallery. More... | |
| class | SGDisplayGroup |
| This DisplayTree node type is used by the SuperGallery The top level(s) of the DisplayTree are made up of a number of SGDisplayGroup nodes, which divide the tree up into categories (and, potentially hierarchical groups within categories). More... | |
| class | SGDisplayItem |
| This DisplayTree node is used by the SuperGallery It is responsible for providing the ability to redraw one item displayed in the gallery, and remembering information on that item (such as its selection state, etc). More... | |

Comment: Used by SuperGallery DisplayTrees This would ideally be a union of all data structures that can be passed into the DisplayTree HandleEvent methods. However, you can't easily do unions of things containing classes with copy constructors, so it isn't a union. Instead, the HandleEvent function has to cast this pointer to the appropriate type for the event being processed. These are: 'NULL' indicates that there is no specific information passed in, and this parameter of the HandleEvent method will be NULL for these event types.

Comment: Used by SuperGallery DisplayTrees This is an enumeration of event types which can be passed to SGDisplayNodes to be handled by their HandleEvent methods. Along with this, a 'SGMiscInfo' structure is always passed in containing relevant information, as well as extra data which is event-specific: The data passed in SGDisplayNode::HandleEvent's 'EventInfo' pointer is determined by the event type. The data will be: MonoOn SGEVENT_FORMAT NULL SGEVENT_REDRAW (SGRedrawInfo *) [SGEVENT_BGREDRAW NULL] -- This event has been replaced by a virtual method SGEVENT_BGFLUSH NULL - May have NULL MiscInfo SGEVENT_MOUSECLICK (SGMouseInfo *) SGEVENT_DRAGSTARTED (DragMessage *) SGEVENT_CLAIMPOINT (SGMouseInfo *) SGEVENT_THUMBMSG (ThumbMessage *) - May have NULL MiscInfo MonoOff NULL indicates that for this event type, a NULL pointer is passed in the EventInfo parameter.

Comment: This structure is passed into SGDisplayNode classes when a sort operation is being applied. It describes how items should be sorted. MonoOn const INT32 MaxSGSortKeys = 2; typedef struct { INT32 SortKey; BOOL Reversed; } SGSortKey; const INT32 SGSORTKEY_NONE = 0; const INT32 SGSORTKEY_BYNAME = 1; MonoOff SortKeys are ALWAYS used in arrays of MaxSGSortKeys length. i.e. SGSortKey SortInfo[MaxSGSortKeys]; Each entry in the SortKey array gives a sort key, specified as as an integer, where 0 means 'no sorting', and other integers are defined by the specific gallery/display item. By default, the value 1 is used to mean 'sort by name', and default gallery handlers are provided by the base classes to provide this sort mode. Each entry also has a Reversed flag which indicates whether the related sort mode should be used in reverse. The MaxSGSortKeys constant is used to allow us to add or remove extra sort keys at will. All references to sort keys should be made by loops which scan from 0 to MaxSGSortkeys-1.
