Hi,
I have a problem...
I have a subclass of Guigfx.mcc. The class dislays a picture. In my
subclass I have an own Draw function. That function draws something on
top of the picture. That works nicely for lines and for circles for
example.
Now I want to draw a filled circle over the picture. How can I do that?
I tried AreaCircle() but that crashes the system imediately. Then I
tried Flood() to fill my Circle, but that seems to have no effect.
For a simple example I used a plain gray picture, drawed a circle and
tried to fill it.
static ULONG test_MUIM_Draw(struct IClass *cl, Object *obj, struct
MUIP_Draw * msg)
{
DoSuperMethodA(cl, obj, (Msg) msg);
{
int iPixelWidth=_mright(obj)-_mleft(obj);
int iPixelHeight=_mbottom(obj)-_mtop(obj);
int iX0= _mleft(obj) + PixelWidth/2;
int iY0= _mtop(obj) + iPixelHeight/2;
SetAPen(_rp(obj), _rp(obj)->AOlPen);
DrawEllipse(_rp(obj),iX0,iY0,20,20);
Flood(_rp(obj),0,iX0,iY0);
}
return (0);
}
So questions:
Why does the example code not fill my circle?
How to correctly draw a filled shape? (Later filling could be the
wrong way as the undelying picture could prevent the circle from
beeing properly filled?)
