This is a class of objects that maintains an internal list of gadgets. Its purpose is to make it easier to layout a group of gadgets. Any gadgets that are a member of a groupgclass object are rendered relative to the groupgclass object's GA_Left and GA_Top attributes. As new gadgets are added to the groupgclass object, the groupgclass object's dimensions grow to enclose the new gadgets. When the groupgclass object receives an OM_DISPOSE message, it not only disposes of itself, it also disposes of all the gadgets in its list. Groupgclass does not support the gadget relative flags (GA_RelWidth, GA_RelHeight, GA_RelBottom, and GA_RelRight).
