One way is to use the widget creation routines to create the window:

b = widget_base( xoffset=xpos, yoffset=ypos )
d = widget_draw( b, xsize=512, ysize=512 )
widget_control, b, /realize
widget_control, d, get_value=window_id

Then you can use WIDGET_CONTROL to get info on the top-level-base:

widget_control, b, tlb_get_offset=xy_pos ; xy_pos=lonarr(2)
widget_control, b, tlb_get_size=xy_size ; xy_size=lonarr(2)

You can also get info using the GEOMETRY keyword to WIDGET_INFO().

You can reposition the widget with TLB_SET_OFFSET keyword to
WIDGET_CONTROL().

I never use IDL's WINDOW command because you have very little
control once you've made the window. It would be simple to make
a procedure to use the widget-creation routines to make a new
window and return the TLB widget ID (maybe as keyword). I do
something similar to this in all of my programs.

Hope this helps.
