Component Interactions in Layout Mode (Simplified)
As illustrated above, there are six components that will interact with each other when the RUI is in Layout Mode. The functionality of each follows
RUI – Monitors user activity and provides dialog windows to support changing modes, choosing Layouts etc. The results of the dialogs and user key-strokes are passed to the appropriate Picture component.
Picture – There will be one Picture for each picture control used by the RUI. While in Layout mode the Picture component monitors the user key strokes to create or destroy instances of the class Object (see glossary Plug-ins) by utilizing the methods offered by the ObjMngr
Object – One or many Plug-in components that maintain a set of attributes which are associated with the type of Object. In Layout mode they will update its image when selected and maintain its image in the context of the background when created or moved.
ObjMngr – Object Manager will create or destroy Object instances and will provide updates to Information as the Objects come and go.
Information – Keeps track of all Objects that are active.
