NAME

       LibDoGadgetMethodA -- DoGadgetMethodA for V37 machines
LibDoGadgetMethod -- Varargs stub for LibDoGadgetMethodA

SYNOPSIS

       result = LibDoGadgetMethodA( Gadget, Window, Requester, Message )
D0 A0 A1 A2 A3
ULONG LibDoGadgetMethodA( struct Gadget *, struct Window *,
struct Requester *, Msg );
result = LibDoGadgetMethod( Gadget, Window, Requester, MethodID, ...)
ULONG LibDoGadgetMethod( struct Gadget *, struct Window *,
struct Requester *, ULONG, ... );

FUNCTION

       Same as the DoGadgetMethod() function of intuition.library V39,
this function invokes a BOOPSI method and provides context
information for classes which implement custom Intuition gadgets.
You should use this function for boopsi gadget objects,
or for "models" which propagate information to gadgets.
Unlike DoMethod(), this function provides a GadgetInfo pointer
(if possible) when invoking the method. Some classes may
require or benefit from this.
On a V39 machine, this function calls the Intuition function.

INPUTS

       Gadget = abstract pointer to a boopsi gadget
Window = window gadget has been added to using AddGList() or AddGadget()
Requester = for REQGADGETs, requester containing the gadget
Msg = the boopsi message to send

RESULT

       The object does whatever it wants with the message you sent,
which might include updating its gadget visuals.
The return value is defined per-method.

NOTES

       This function invokes the specified method with a GadgetInfo
derived from the 'Window' and 'Requester' pointers. The GadgetInfo
is passed as the second parameter of the message, except for
OM_NEW, OM_SET, OM_NOTIFY, and OM_UPDATE, where the GadgetInfo
is passed as the third parameter.
Implementers of new gadget methods should ensure that the
GadgetInfo is the second long-word of their message!
