BOOPSI — Basic Object-Oriented Programming System

Overview

BOOPSI is AmigaOS's class-based object system for Intuition gadgets and images. Objects receive messages via DoMethod() and support inheritance and notification.

Core Methods

Method	Description
`OM_NEW`	Create new object
`OM_DISPOSE`	Destroy object
`OM_SET`	Set attributes
`OM_GET`	Get attributes
`OM_UPDATE`	Attribute changed notification
`OM_NOTIFY`	Send notification to targets
`GM_RENDER`	Render the gadget
`GM_GOACTIVE`	Gadget activated by user
`GM_HANDLEINPUT`	Process input while active
`GM_GOINACTIVE`	Gadget deactivated

Built-in Classes

Class	Description
`rootclass`	Base class for all BOOPSI objects
`gadgetclass`	Base gadget class
`imageclass`	Base image class
`strgclass`	String entry gadget
`buttongclass`	Button gadget
`propgclass`	Proportional slider
`groupgclass`	Group container
`frbuttonclass`	Framed button
`frameiclass`	Frame image
`sysiclass`	System images (checkmark, etc.)
`icclass`	Interconnection (maps attributes)
`modelclass`	Model for MVC pattern

Creating and Using Objects

Object *button = NewObject(NULL, "frbuttonclass",
    GA_Left,     20,
    GA_Top,      40,
    GA_Width,    100,
    GA_Height,   20,
    GA_Text,     "Click Me",
    GA_ID,       42,
    GA_RelVerify, TRUE,
    TAG_DONE);

AddGadget(win, (struct Gadget *)button, -1);
RefreshGadgets((struct Gadget *)button, win, NULL);

/* Set attribute: */
SetGadgetAttrs((struct Gadget *)button, win, NULL,
    GA_Disabled, TRUE,
    TAG_DONE);

/* Get attribute: */
ULONG value;
GetAttr(GA_Disabled, button, &value);

/* Cleanup: */
RemoveGadget(win, (struct Gadget *)button);
DisposeObject(button);

Writing a Custom Class

Class *myclass = MakeClass(NULL, "gadgetclass", NULL,
                           sizeof(struct MyData), 0);
myclass->cl_Dispatcher.h_Entry = (HOOKFUNC)myDispatcher;

ULONG myDispatcher(Class *cl, Object *o, Msg msg) {
    switch (msg->MethodID) {
        case OM_NEW:    return myNew(cl, o, (struct opSet *)msg);
        case OM_DISPOSE: return myDispose(cl, o, msg);
        case GM_RENDER: return myRender(cl, o, (struct gpRender *)msg);
        default:        return DoSuperMethodA(cl, o, msg);
    }
}
