Hello there,

the command "xwininfo -tree" will tell you everything you want to
know. I used it to debug my screen grab recipe, which traverses the
entire window tree.

The output looks like this:

xwininfo -tree

xwininfo: Please select the window about which you
          would like information by clicking the
          mouse in that window.

xwininfo: Window id: 0x1800191 "reply to address@hidden - XEmacs 21.4 (patch 
12) "Portable Code" [/usr/X11R6/bin/xemacs]"

  Root window id: 0x37 (the root window) (has no name)
  Parent window id: 0xa00fd4 (has no name)
     1 child:
     0x1800192 (has no name): ()  640x605+0+0  +87+45
        3 children:
        0x1800199 (has no name): ()  15x505+621+66  +708+111
        0x1800194 (has no name): ()  640x580+0+25  +87+70
        0x1800193 (has no name): ()  638x23+0+0  +87+45
