NAME

        space_gc -- a placeholder gadget class.

SUPERCLASS

        gadgetclass

REQUIRES

        bevel.image

DESCRIPTION

        This class does more than just take up space. space.gadget allows you 
to create a GREL or layout resizable input areabox. You might render
custom graphics in the area, for example, a icon editor graphic area
might be based on space.gadget. This lets space.gadget handle its
domain in a way compatible with not only the present layout, but any
future custom layout domain methods. The application can handle rendering
and clipping in this area on the application task. It presently sends
notification of Mouse X/Y and the inner custom application rendering area
of the space accounting for any outer bevel (including preference bevel
sizes changes).

METHODS

        OM_NEW -- Create the space gadget.  Passed to superclass.
OM_SET -- Set object attributes. Passed to superclass first.
OM_DISPOSE -- Passed to superclass.
OM_UPDATE -- Set object notification attributes & render.
Passed to superclass first.
OM_NOTIFY -- Notify object attributes. Passed to superclass first.
GM_RENDER -- Renders the gadget imagery. Overrides the superclass.
GM_HITTEST -- always returns GMR_GADGETHIT, as long as the gadgets
GA_ReadOnly attribute isn't set.
GM_GOACTIVE -- Passed to superclass first. Then sends mouseevent
notification.
GM_HANDLEINPUT -- Handles input events once active. Overrides the
superclass. As long as the user keeps the mouse button pressed,
the gadget sends notification events to its ICA_TARGET.
GM_GOINACTIVE -- Passed to superclass. A final notification is sent.
GM_DOMAIN -- Calculates mix/max sizes. Overrides the superclass.
All other methods are passed to the superclass.
