NAME DoGadgetMethodA -- Invoke method on a boopsi gadget. (V39) DoGadgetMethod -- Varargs stub for DoGadgetMethodA(). (V39) SYNOPSIS result = DoGadgetMethodA( Gadget, Window, Requester, Message ) D0 A0 A1 A2 A3 ULONG DoGadgetMethodA( struct Gadget *, struct Window *, struct Requester *, Msg ); result = DoGadgetMethod( Gadget, Window, Requester, MethodID, ...) ULONG DoGadgetMethod( struct Gadget *, struct Window *, struct Requester *, ULONG, ... ); FUNCTION Same as the DoMethod() function of amiga.lib, but provides context information and arbitration 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. 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!
