Yes, but i cant get idcmp events only by windows. Screens cant !!

Ok, what i'll do is to setup a CGFX screen (640x480x8) ans open a
backdrop | borderless window. I'll catch every IDCMP events.
Now i got an other prob. I want to double buffer this window. How can i do
it in CGFX ??? I mean, all docs i have deals with double buffer in planar.
Is it a different way to handle it with a CGFX screen ?
If some1 have some example, i'll be glad to have some...
