since the mousewheel function does not support hscrolling, i've written my own scrollwheel handler using the osx api which works fine but it "steals" the scrollwheel from my patcher window.

is it possible to access the patchers scrollbar position, something like this:

OSStatus arrange_handleWindowEvent (EventHandlerCallRef callRef, EventRef theEvent, myMaxObject *x)

    if ( GetEventClass (theEvent) == kEventClassMouse)

        if (GetEventKind (theEvent) == kEventMouseWheelMoved)

status = GetEventParameter( theEvent, kEventParamKeyModifiers, typeUInt32,

                                     NULL, sizeof(modifiers), NULL, &modifiers );

status = GetEventParameter( theEvent, kEventParamMouseWheelAxis,

                                     typeMouseWheelAxis, NULL, sizeof(axis), NULL, &axis );

status = GetEventParameter( theEvent, kEventParamMouseWheelDelta,

                                     typeLongInteger, NULL, sizeof(delta), NULL, &delta );

                if(x->mouseInside) // if mouse is inside my object move my objects scrollbar

                    myMaxObject_vScrollbarMove(x, -delta); ///this works fine

                return noErr;

            else if ( axis == kEventMouseWheelAxisX )

                if(x->mouseInside) // if mouse is inside my object move my objects hScrollbar

                    myMaxObject_hScrollbarMove(x, -delta);//this works fine

        else return eventNotHandledErr;

hello everybody,
since the mousewheel function does not support hscrolling, i've written my own scrollwheel handler using the osx api which works fine but it "steals" the scrollwheel from my patcher window.

mousewheelhorizontal-scrolling

I am not sure what you mean here, but the mousewheel method does support both horizontal and vertical scrolling.

void yourobj_mousewheel(t_yourobj *x, t_object *patcherview, t_pt pt, long modifiers, double dx, double dy);

dx and dy hold the scrolling delta information.

thanks so much, i' m so stupid i guess...
