Stacks of Pixmaps

[olivier valentin <olivier valentin ensisun imag fr>]

I'm developping a game with playcards.
In the main window, there is fixed.
On the fixed several eventboxes.
And in those eventboxes, pixmaps.
I can't manage to set the drawing order of these pixmaps. Some cards
should mask part of others, but they seem to be always drawed in the creation
order.

How can i set this order?

I tried to do a xwininfo -tree ; it returns:

xwininfo: Window id: 0x3400096 "client"

  Root window id: 0x29 (the root window) (has no name)
  Parent window id: 0x1800153 (has no name)
     1 child:
     0x34000a6 (has no name): ()  250x500+10+10  +416+107
        9 children:
        0x34000af (has no name): ()  71x96+100+400  +516+507
        0x34000ae (has no name): ()  71x96+20+400  +436+507

        0x34000a7 (has no name): ()  71x96+80+400  +496+507

Thanks for advance.
