Here's the draw method:
dim b As Integer
if not AlreadyInited then b=me.MakeTransparentMBS
dim p,q As Picture
dim x As Integer
dim y As Integer
p=DefaultPicture
q=MaskPicture
self.Width=p.Width
self.Height=p.Height
DisableScreenUpdatesMBS
Pict=CGCreateImageMBS(p,q)
AlreadyInited=True
'me.Refresh
self.InvalidateShadowMBS
EnableScreenUpdatesMBS
AlreadyInited is a property of type boolean, DefaultPicture and
MaskPicture are parameters of type picture and Pict is a CGImageMBS
property.
This method is called both in the open event of the window and in the
method to change the current picture.
This is the paint event:
dim c as CGContextMBS
if pict=nil then Return
c=self.CGContextMBS
c.ClearRect CGMakeRectMBS(0, 0, g.width, g.height)
c.drawPicture pict, CGMakeRectMBS(0, 0, pict.width, pict.height)

It's a plain RS window, with MacProcID 1104.

I draw with a CGContext only in the paint event, but I need to
invalidate in the other method (look at the commented "me.refresh"
line above, it's what I need to replace by flush), where the CGContext
object of the paint event doesn't exist (and doesn't make sense
outside of it).
